[Truncated abstract] Autologous Chondrocyte Implantation (ACI) has shown early clinical success as a repair procedure to address focal articular cartilage defects in the knee, and involves isolating and culturing a patient's own chondrocytes in vitro and re-implantation of those cells into the cartilage defect. Over time, repair tissue can develop and remodel into hyaline-like cartilage. A progressive partial weight bearing (PWB) program becomes the critical factor in applying protection and progressive stimulation of the implanted cells, to promote best chondrocyte differentiation and development, without overloading the graft. The aim of this thesis was to investigate whether patients could replicate this theoretical load bearing model to possibly render the best quality tissue development. In addition, this proposed external load progression is only a means to loading the articular surface. Several factors, including those that may result from pathology, have the potential to influence gait patterns, and therefore, articular loading. The association between increasing external loads (ground reaction forces - GRF) and knee joint kinetics during partial and full weight bearing gait was, therefore, investigated in the ACI patient group, as was the contribution of other gait variables to these knee joint kinetics which may be modified by the clinician. Finally, current weight bearing (WB) protocols have been based on early ACI surgical techniques. With advancement in the surgical procedure and ongoing clinical experience, we employed a randomised controlled clinical trial to assess the effectiveness of an 'accelerated' load bearing program, compared with the traditionally 'conservative' post-operative protocol. ... Although similar spatio-temporal, knee kinematic and external loading parameters were observed between the traditional and accelerated rehabilitation groups, the accelerated group was 'more comparable' to the controls in their external knee adduction and flexion moments, where the traditional group had lower knee moments. Knee moments greatly affect knee articular loading, and large adduction moments have been related to poor clinical outcomes after surgery. Therefore, the return of normal levels may be ideal for graft stimulation, however, may overload the immature chondrocytes. Acceleration of the intensive rehabilitation program will enable the patient to return to normal activities earlier, whilst reducing time and expenses associated with the rehabilitative process, and may enhance long-term tissue development. However, continued follow-up is required to determine if there are any detrimental effects that may emerge as a result of the accelerated load bearing program, and assess the recovery of normal gait patterns and whether longer term graft outcomes are affected by the recovery time course of normal gait function, and/or abnormal loading mechanics in gait. Furthermore, analysis at all levels of PWB is needed to identify a more complete set of variables attributing to the magnitude of external knee joint kinetics and, therefore, knee articular loading, while the influence muscle activation patterns may have on articular loading needs to be investigated. This becomes critical when you consider loads experienced by the articular surface throughout the early post-operative period following ACI may be important to short- and long-term graft development.

The present study is part of a larger and ongoing research initiative investigating the cumulative cognitive effects of mild head injury in rugby union and focused specifically on high school rugby players. A comprehensive battery of neuropsychological tests was administered to top team high school rugby players (n = 47), and a non-contact sport control group of top team high school hockey players (n = 34). Direct comparisons of group mean scores and standard deviations across each neuropsychological test were carried out for the Total Rugby group versus the Total Hockey group as well as for the subgroups Rugby Forwards versus Rugby Backs. A correlational analysis was conducted to ascertain whether a relationship exists between the number of mild head injuries reported by the players and their cognitive test performance. Results of the group comparisons of means and variability on WMS Paired Associate Learning Hard Pairs - Delayed Recall provides tentative indications of the initial stages of diffuse damage associated with mild head injury in the rugby group and provides some evidence for impairment of verbal learning and memory in the Rugby Forwards group. The correlational analysis revealed no significant relationship between number of reported mild head injuries and cognitive performance. The findings and possible latent effects of the multiple mild head injuries reported by the rugby players are discussed in terms of brain reserve capacity theory and suggestions for future research are provided.

This study aims to explore, and to a certain extent to clarify, what it means psychologically to experience Traumatic spinal cord injury (TSCI) in a South African spinal unit. The target time chosen for analysis is the acute medical period. The study presents a review of the literature on psychological adjustment to TSCI and then proceeds to introduce and extensively articulate the hermeneutic approach and methodology. Subsequently, an interpretive research strategy is presented for the purpose of studying the acute phase of TSCI. The data for the study was obtained by means of three dialogical interviews which were tape recorded, transcribed and analyzed with~n a cyclical framework consisting of three interdependent levels. The interpretive procedure is modeled upon the 'reading guide' developed by Brown, Tappan, Gilligan, Miller and Argyris (1989). The analysis follows a course from the individual psychological descriptions of the experience to the generation of a general, nomothetic narrative account of the acute phase. The findings are then discussed in relation to the existing literature and evaluated on the basis of the goals of the study. The study highlights the value of some of the 'stage' ways of thinking about SCI adjustment, while simultaneously stressing the need for placing adjustment within a more personalized, and individually meaningful context. Significant differences between the psycho-physical experiences of patients in the categories of complete and -incomplete SCI were found, which suggests that a sharper distinction be made in the literature between these two groups, in order to account for the marked variations in their experiences.-- The study also contains a number of shortcomings, such as a lack of understanding about certain historical and contextual factors which may have mediated the experiences of the trauma for the individuals concerned. These shortcomings and some suggestions fro their resolution are then discussed. The study concludes with an evaluation of the research strategy and methodology and also offers some suggestions for future research.

Memory impairment is an outcome of Traumatic Brain Injury (TBI), and associated with lower levels of post-morbid adjustment. This research isolated the memory impairment of retrieval deficit, and examined the efficacy of cues and mnemonics in remediating the impairment. Thirty-three male and female TBI survivors, 18 to 71 years old, were pre-tested for attention (COPY), short-term memory (SD), long-term memory (LD) and recognition memory (RS) employing the Rey Osterrieth Complex Figure Test (CFT), and Subtest. Sixteen subjects demonstrating a retrieval deficit were administered the post-test, with even random assignment into four treatment conditions: a control group (CONTROL), a group administered cues (CUES), a group administered mnemonics {MNEM), and a group administered mnemonics and cues (BOTH) (n = 4). A MANOVA revealed a significant effect of TRIAL (p5.05), no significant effect of TREATMENT, and no interaction. A power analysis indicated the lack of TREATMENT effect could be the result of sample size. Post-hoc t tests revealed a difference across TRIAL for SD and LO in the two experimental conditions which utilized mnemonics. The sample was divided into two groups according to subjects' level of functioning (HIGH and LOW). A MANOVA showed main effects for LEVEL for SD and RS, for TRIAL for SD, LO, and RS, and a LEVEL by TRIAL interaction for COPY (R

The study purposes were to identify changes in resilience, satisfaction with life (SWL), depression, spirituality, and functional independence (FI) and to examine the relationship between these variables, during the inpatient rehabilitation for a spinal cord injury (SCI). The sample included 42 individuals with a SCI, 33 males and 9 females, who were inpatients with a mean stay of 52 days (SD = 15.78). A repeated measures design was employed with questionnaires completed at three times during rehabilitation. Results indicated that there were significant changes in depression, satisfaction with life, spirituality, and FI during inpatient rehabilitation. Findings also indicated significant correlations between resilience, SWL, spirituality, and depression. Future studies developing interventions, and examining factors that predict resilience could help build resilience and may improve rehabilitation outcomes.

As a result of medical advancement and cultural patterns of Western society, traumatic head injury is increasingly a problem for the injured, their families, medical and social services professionals, and the community at large. Head trauma is remarkable because of the complex nature of the residual disabilities which include long lasting cognitive and emotional problems, social isolation, and family disruption. The purpose of this study was to re-examine the phenomenon of recovery after mild to moderate head injury using an ethnographic research approach. The data were based on the experiences of 21 disabled and their families in the community setting. The disabled represented a range of stages of recovery and severity of disability. The data was collected using three field work strategies: extensive semi-structured interviews, participant observation, and non-academic document review. After collection the data was subjected to thematic and content analysis, that resulted in the selection of themes that characterized the experiences for the head injured and their families. The themes for the head injured informants were: dead days, loneliness, and forgetting. The family members' experiences were represented in the themes: responsibility, vulnerability, tough love, gender differences, and reactions to the experience. Next the data were interpreted using five theoretical concepts from cultural anthropology: liminality, personhood, social labelling, sick role and double bind. In addition, the reflexive influence of the investigator on the research process was addressed. The trustworthiness of the ethnography was assessed in terms of credibility, transferability, dependability and confirmability. Several variables were found to be important to the long term outcome of head injury. These variables were: family directed therapy, double bind communication patterns, and lifelong recovery. Two other factors were found to be critical for the recovery of the head injured. These were economic disincentives to the return to employment and the importance of the social and family environment. In the final section the research and policy implications of the study were discussed in relation to management and service provisions.

This longitudinal, descriptive study based on Bandura's self-efficacy theory (1977), examined the effects of educational activities on self-efficacy and of self-efficacy on functional ability in everyday activities in clients undergoing elective, primary, unilateral, total knee arthroplasty (TKA). Educational activities included: attending a joint replacement class and a physical therapy session, performing exercises, and reading educational materials. Other sources of client information were also discussed. Self efficacy was assessed regarding confidence in ability to perform activities required for discharge home. Cronbach's alpha for the self-efficacy scale was .94 (pre-education) and .81 (post-education). Functional ability in everyday activities was operationalized as length of hospital stay, discharge placement, and perceived health status. Perceived health status was assessed using the three-scale Western Ontario McMasters University Osteoarthritis Index (WOMAC). Cronbach's alpha was: pain .85, joint stiffness .76, and physical function .94 (preoperatively); and pain .86, joint stiffness .80, and physical function .94 (postoperatively).Evidence was collected from a convenience sample of 31 participants: (a) when the process of scheduling surgery began; (b) before surgery, after the client had opportunities to participate in educational activities, and (c) approximately six weeks after surgery. The orthopedic surgeon and professional staff reviewed instruments for validity. Five clients reviewed the questionnaires for understandability and readability. Data were analyzed using Pearson r correlation coefficients, independent samples t-tests, analyses of variance and chi-square tests. An alpha level of .05 was designated as significant.Higher self-efficacy scores were associated with more expected benefits, previous TKA, and greater pain relief. Lower self-efficacy scores correlated with greater improvement in self-efficacy. Shorter lengths of hospital stay were associated with greater joint stiffness reduction, younger age and previous TKA. Discharge home was associated with younger age and living with someone else. Participants that were "very sure" of the need for TKA exhibited higher self-efficacy scores than participants that were "unsure". Improved outcomes were not associated with any one type of educational activity.This study highlighted the need for further refinement of context sensitive self-efficacy instruments, more sophisticated means of assessing the impact of an increasing array of information sources and more longitudinal studies with larger sample sizes.

Social Skills Training for Head Injured Adults Research has demonstrated numerous personality and behavioral disturbances resulting from head injury (Lezak,1978). It is these changes rather than the physical disabilities that create the stress, in the long term for the relatives of the head injured (MeKinley,1981). Therefore, social skills training is a important part of intervention with this population. This study evaluates a social skills training program "Stacking the Deck" (Braunling-McMorrow et al 1986) which has been modified to include structured learning assignments. This is a single case evaluation (A - Baseline, B - Treatment) with replication. The subjects are four males with severe head injuries, ages 19,22,34,and 36. Social skills were described as requiring an action or reaction within six skill areas: compliments, social interaction, politeness, criticism, social confrontation, and questions/answers. Measures include the baseline developed in the "Stacking the Deck" program, Staff Questionnaire on Social Behavior (Spence,1979) and the Social Skills Assessment Chart (Spence,1980). Results indicate that this is an effective program for social skills training with the adult head injured population.

It is generally supposed that a supportive family can have an influence on outcomes for an adult with severe brain injury, but there is very little known about what effective families actually do. In this research the families of five such individuals were involved in an ethnographic project that lasted for one year. The literature review brought together insights from brain injury, care ethics, disability studies and anthropology. These insights were combined with a process of reflective equilibrium that was applied to the ethnographic material in order to determine the ethics of the carers. Ethics of care in this setting was conceived of as a positive practice ethic, rather than as a series of negative conundrums posed by the brain injury. The practice ethic shared by carers meant that they all conceived of the need created by brain injury in humanistic terms, rather than in terms of pathology. Carers demonstrated virtues appropriate to their practice as they helped the adult with brain injury to connect with aspects of ordinary life. The best outcomes for the adult with brain injury included being able to engage in productive activity and to make a place in the world. These outcomes could only be achieved with due regard for their safety and subsistence. The practice ethic of carers was demonstrated in the skills and concern that ensured a satisfactory outcome for the adult with brain injury. This research is a departure from recent research about families affected by brain injury, which has focused on the burden involved in care. An examination of what carers achieve suggests that burden may be associated with the development of caring practice. The transformative capacity of care, for both the carer and the adult with brain injury, is emphasized. However contextual factors, such as adequate compensation, are connected to the capacity of the carer to engage in good practice and these are explored also in this thesis. In particular, relevant aspects of the relationship between families and the Accident Compensation Corporation are explored.

This study investigated the use of biofeedback as part of stress-management training program with head injured adults. The single cases examined were four males with head injuries of moderate severity who were in the post-acute stages of recovery. Treatment involved bi-weekly relaxation training, using EMG biofeedback in combination with deep breathing, autogenic training and/or imagery. Individual subject response to relaxation training was examined during treatment sessions, as was the frequency of stress-related symptomatology outside of sessions, and overall functional adaptation. While all subjects showed evidence of relaxation during treatment sessions, such factors as the nature of the functional disturbance and personal motivation appear to be related to the degree of carryover to the external environment.

ENGLISH ABSTRACT: The traumatic nature of spinal cord injury (SCI) imposes major and permanent life changes that necessitate physical, social and vocational adjustments for the individual, as well as placing strain on the family. The importance of psychological aspects of adjustment and rehabilitation has progressively become recognised as an integral part of facilitating a higher quality of life for individuals and their families living with SCI. While it has been established that psychological disturbance is not an inevitable long-term consequence of SCI, researchers have found that a proportion of this population has marked difficulty adapting psychologically to their new lifestyle and the challenges it poses. It has been found that the SCI population has an increased risk for divorce, substance abuse, self-neglect and suicide. In the mid-1990's, researchers involved in SCI rehabilitation started developing cognitivebehaviour therapy (CBT) interventions to assist individuals with their psychological adjustment to the traumatic injury. Lazarus and Folkman's (1984) cognitive theory of stress and coping has been the theoretical grounding for some of these interventions. The primary objective of this literature review is to ascertain the effectiveness of CBT in assisting individuals with their psychological adjustment to SCI and to make recommendations for future research in this area.
AFRIKAANSE OPSOMMING: Die traumatiese aard van 'n spinale koord besering (SKB) veroorsaak 'n beduidende en permanente lewensverandering, wat fisieke-, sosiale- en werksaanpassing vir die individu verg, asook spanning op die familie plaas. Die belangrikheid van sielkundige aspekte rakende aanpassing en rehabilitasie word toenemend herken as 'n integrale deel in die fasilitering van 'n hoër kwaliteit van lewe vir die individue en hulle families wat lewe met 'n SKB. Alhoewel daar gevind is dat sielkundige versteuring nie 'n noodwendige langtermyn gevolg van 'n SKB is nie, het navorsers wel gevind dat 'n gedeelte van die populasie beduidende sielkundige aanpassingsprobleme ervaar ten opsigte van hul nuwe lewenstyl en uitdagings. Daar is gevind dat die SKB populasie 'n verhoogde risiko loop vir egskeidings, substansmisbruik, self-verwaarlosing en selfmoord. In die middel van die 1990's, het SKB- en rehabilitasie-navorsers kognitiewe-gedragsterapie (KGT) intervensies ontwikkelom individue te help met sielkundige aanpassing na 'n SKB. Lazarus en Folkman's (1984) se kognitiewe teorie oor stres en streshantering, het die teoretiese grondslag gevorm vir sommige van hierdie intervensies. Die primêre doel van hierdie literatuuroorsig is om die effektiwiteit van KGT te bepaal in die ondersteuning van individue met sielkundige aanpassing na SKB, en om voorstelle te maak oor toekomstige navorsing wat met hierdie onderwerp verband hou.

The development of emergency department medical interventions and the implementation of fast-transport trauma systems has decreased the rate of death resulting from traumatic brain injury (TBI). Without corresponding methods for long-term treatment and recovery, the prevalence of people disabled by TBI has increased, creating a growing public health problem. Investigations generated by physicians, rehabilitation programs, and social scientists, which attempt to associate standard measures of injury severity with outcome, leave unexplained variance in long-term functional status for persons with TBI. The purpose of this investigation was to use persons with brain injury and their family members, to guide an analysis of the factors that foster successful recovery from brain injury. Three studies were conducted. In Study #1, the method for observation generated by Kurt Goldstein (1934) was adopted to conduct 20 case studies of persons who sustained brain injury. The Schema of the EsEx Couple (Maynard. 1992) was used to orient the investigation. The EsEx Couple Schema proposes that events in human life must be understood by considering the whole system of Person (Essence) in the Environment (Exchange), and the transactions that flow in a recursive loop from Person to Environment and back. Kurt Goldstein's Laws of Organismic Life (1934), a model consistent with that of the EsEx Couple, was used to evaluate the data. Strong patterns associated family and social networks, autonomy, and perceived self-determination with higher levels of recovery, and were used to generate a Model for Recovery. In Study #2. the Motivational Analysis of Self-Systems Processes (Connell & Wellborn, 1991) was combined with results from Study #1 to generate a Development Model, and to build a survey which was administered to 248 persons with brain injury. Results (1) confirmed the model, indicating factors that contribute to recovery were hypothesized measures of Social Context, Perception, and Engagement; and (2) established a valid instrument, generated by persons with brain injury and their families, for measuring functional status. In Study #3. results of the survey research were used to return to the case studies to consider where individual lives differ from expected patterns, and why. Deviations from expected patterns were explored to identify how individual differences operate to affect outcome. Recommendations for clinical practice include (1) directing interventions toward family as well as patient, as a method of enhancing the Social Context for the patient, and (2) using careful evaluation of each patient's idiosyncrasies to consider individual interventions.

ENGLISH ABSTRACT: Background Traumatic spinal cord injury (SCI) remains one of the most serious and devastating injuries often resulting in permanent disability and with life changing implications for the individual and his/her family. Successful reintegration into community life and employment after SCI is considered important goals of rehabilitation as this has been positively associated with quality of life, self esteem and life satisfaction. The International Classification of Functioning, Disability and Health (ICF) allows researchers to identify the impact of environmental factors on functioning and disability. Minimal research, particularly in South Africa, has been done on the impact of the environment on persons living with various health conditions and specifically spinal cord injury. Objectives The main purpose of this study was to describe and compare the level of participation of persons with traumatic SCI at two time points (discharge and six months after discharge) from the inpatient rehabilitation setting and to identify the environmental barriers experienced. Methods A prospective, descriptive study was conducted using consecutive sampling. All patients with traumatic SCI that were discharged from September 1, 2008 from the Western Cape Rehabilitation Centre (WCRC) who were eligible for this study were included. Two questionnaires (one based on the ICF and one purposely-developed) and the International Standards for the Classification of SCI (ISCSCI) were used. Data were analyzed with the statistical software package STATISTICA. Results A person sustaining a traumatic SCI in the Cape Metropolitan area of the Western Cape Province is most likely to be a male, young (20 to 29 years), of the Black or Coloured race and living in the Cape Flats suburbs. More than half of the subjects had a grade eight to ten level of education which together with the lack of employers’ responsibilities towards part-time workers might explain the low percentage (11%) of employment at six months after discharge from the WCRC. Complete paraplegia, occurring mainly in the thoracic cord, was the most common neurological disability found in this study. The most common secondary condition was pain followed by spasticity limiting function. The low incidence of pressure sores and urinary tract infections found in this study contradicts findings of previous studies.The majority of the subjects were discharged to the same house they were living in at the time of their injury. However, due to various architectural barriers, some of them were not able to function independently in their homes. Inaccessibility of public transport, the lack of recreational and sport facilities, lack of social support structures in the community and inadequate financial resources were the main environmental barriers experienced by these individuals. Conclusion The main finding of this study was the low employment rate and the difficulty experienced with reintegration at community level after SCI. The results of this study confirm the significant contribution of environmental factors in participation, especially those of transport and education in return to work. Fourteen years after the publication of the Integrated National Disability Strategy (INDS) White Paper (1997), legislative strategies to ensure that people with disabilities have equal access to social and economic opportunities remain lacking.
AFRIKAANSE OPSOMMING: Agtergrond Traumatiese spinaalkoordbesering (SKB) lei dikwels tot permanente verlamming en dit het lewensveranderende implikasies vir die individu en sy/haar familie. Suksesvolle herintegrasie in die gemeenskap en werkverrigting na SKB is belangrike doelstellings vir rehabilitasie omdat dit positief met lewenskwaliteit, selfrespek en lewens-bevrediging geassosieer word. Die Internasionale Klassifisering van Funksionering, Gestremdheid en Gesondheid (IKF) bied aan navorsers die geleentheid om die impak van omgewingsfaktore op funksionering en gestremdheid te identifiseer. Daar is veral in Suid-Afrika beperkte navorsing oor die impak van die omgewing op mense met verskillende gesondheidstoestande, spesifiek SKB. Doel Die hoofdoel van hierdie studie was om die vlak van deelname van mense met traumatiese SKB op twee verskillende tye te beskryf en te vergelyk, onmiddellik na hulle uit die rehabilitasiesentrum ontslaan is, en ses maande later. Die studie het ook ten doel gehad om die omgewingsfaktore te identifiseer wat deelname negatief beïnvloed. Metode Daar is van ’n beskrywende studie gebruik gemaak. Alle pasiënte met traumatiese SKB wat vanaf 1 September 2008 vanaf die Wes-Kaapse Rehabilitasiesentrum (WKRS) ontslaan is en wat voldoen het aan die insluitingskriteria is ingesluit. Twee vraelyste is gebruik om data in te samel – een is op die IKF gebaseer en een is spesifiek vir die studie ontwikkel. Daar is ook van die Internasionale Standaarde vir die Klassifisering van SKB (ISKSKB) gebruik gemaak om data in te samel. Data is met behulp van STATISTICA, ’n statistiese sagteware pakket, geanaliseer. Resultate Iemand wat ’n traumatiese SKB in die Kaapse metropolitaanse gebied van die Wes-Kaap provinsie opdoen, is mees waarskynlik ’n jong man (20 tot 29 jaar) van die Swart of Kleurling ras wat woonagtig in die voorstede op die Kaapse Vlakte is. Meer as die helfte van die deelnemers in die studie het slegs ’n opvoedingsvlak van graad agt tot tien. Hierdie aspek, tesame met die gebrek aan werkgewers se verantwoordelikheid teenoor deeltydse werknemers is dalk die rede waarom slegs 11% van die deelnemers ses maande na hulle uit die WKRS ontslaan is, werksaam was. Volledige paraplegie, hoofsaaklik as gevolg van ’n besering van die torakale spinaalkoord, was die algemeenste neurologiese besering wat in hierdie studie gevind is. Die algemeenste sekondêre komplikasie wat voorgekom het, was pyn gevolg deur spastisiteit. Die lae voorkoms van druksere en urienweginfeksies in dié studie is in teenstelling met bevindings van vorige studies. Die meeste deelnemers is ontslaan na dieselfde huis waar hulle voor die besering gewoon het, maar as gevolg van verskeie argitektoniese hindernisse, kon sommige van hulle nie onafhanklik binne hulle wonings funksioneer nie. Die ontoeganklikheid van openbare vervoer, die gebrek aan ontspannings- en sportfasiliteite, die gebrek aan sosiale ondersteuningsnetwerke in die gemeenskap en onvoldoende finansiële hulpbronne was die algemeenste omgewingshindernisse wat deur die deelnemers ondervind is. Samevatting Die belangrikste bevinding van dié studie was dat slegs ’n klein persentasie van die deelnemers ses maande na hul ontslaan is, werksaam was en dat herintegrasie in die gemeenskap na ’n SKB baie moeilik is. Die resultate van die studie bevestig die belangrike rol wat omgewingsfaktore by deelname speel, veral die faktore wat te make het met vervoer en die opvoedingsvlak wanneer daar na ’n werk teruggekeer word. Veertien jaar na die publikasie van die Geïntegreerde Nasionale Gestremdheidstrategie in 1997, is wetgewende strategieë om gelyke toegang tot sosiale en ekonomiese geleenthede vir persone met gestremdhede te verseker, steeds gebrekkig.

Background: Traumatic injury remains a major cause of mortality in the US. Older Americans experience lower rates of injury and higher rates of death at lower injury severity than their younger counterparts. The objectives of this study were to explore pre-injury factors and injury patterns that are associated with post-discharge mortality among injured elderly surviving index hospitalization. Methods: We queried a 5% random sample of Medicare beneficiaries (n=2,002,420) for any hospitalization with a primary ICD-9 diagnosis code for injury. Patients admitted without urgent/emergent admission were excluded, as well as patients presenting from inpatient hospitalization or rehabilitation. The primary endpoint was all-cause mortality. Patients were categorized into three mortality groups: death within 0-30 days, 31-90 days, or 91- 365 days post-discharge from the index hospitalization. These groups were compared with those who survived greater than one year post-discharge. Univariate tests of association and multivariable logistic regression models were utilized to identify factors associated with mortality during the 3 examined periods. Results: 83,439 elderly patients (4.2%) were admitted with new injuries. 63,628 met inclusion criteria. 1,936 patients (3.0%) died during their index hospitalization, 2,410 (3.8%) died within 0-30 days, 3,084 (4.8%) died within 31-90 days, and 5,718 (9.0%) died within 91- 365 days after discharge. In multivariable adjusted models, advanced age, male sex, and higher Elixhauser score were associated with post-discharge mortality. The presence of critical injury had the greatest effect on mortality early after injury (0-30 days, OR 1.81, CI 1.64-2.00). Discharge to anywhere other than home without services was associated with an increased odds of dying. Conclusions: Socio-demographic characteristics, disposition, and co-morbid factors were the strongest predictors of post-discharge mortality. Efforts to reduce injury-related mortality should focus on injury prevention and modification of co-morbidities.

This study aimed to determine health promotion needs of physically disabled youth with spinal cord injury. The study specifically explored health-related behaviours with reference to participation in physical activity and substance usage, factors that influenced these behaviours and major issues that needed to be targeted in health promotion.

The purpose of this study was to document the effects that a regular yoga therapy practice has on the quality of life for a paraplegic individual. Due to the unique nature of spinal cord injury (SCI), this was a case study with one participant. For 5 weeks the subject practiced a standardized yoga routine three times a week with a yoga teacher, receiving private instruction. Interview questions were asked before and after the intervention to document the participant's quality of life. Each week, the subject completed a modified SF-36 questionnaire as well as Cohen's Perceived Stress Survey. Perceived pain and perceived stress were the two primary variables monitored in the study. The results of this study demonstrated a slight reduction in perceived stress, a reduction in perceived pain, and an improvement in overall quality of life. Additionally, the subject increased her strength significantly from the beginning to the end of the study. Based on the findings in this study, it appears that a regular adapted yoga routine is beneficial for paraplegic individuals.

The current project applied a new theoretically-driven training paradigm shown to be effective at improving memory performance in a group of aging adults (Jennings & Jacoby, 2003) to a group of 10 individuals with Acquired Brain Injury (ABI). Training effects were assessed on the paradigm itself and other measures of memory and attention. Performance on cognitive measures was compared to a group of 9 healthy, young adults to control for practice effects. Results showed a replication of previous findings in terms of both frequency and magnitude of improvement in this new population. Some proximal effects of training were found on a similarly-structured task (false fame) but no distal effects of training were seen on other cognitive measures. Limitations of the current project included small sample sizes. Recommendations are provided for future research. Implications for a dual-process model of memory and clinical practice are discussed.

Introduction: Garment work is repetitive and detailed and requires constant use of the hands. It is no surprise that garment workers are at high risk for developing repetitive strain injuries (RSI’s) (MFL Occupational Health Centre, 1999). Work-related upper limb disorders, popularly known as RSI’s, affect over 370,000 people in Great Britain with 86,000 new cases recorded in 2010. This costs employers almost £300 million in lost working time, sick pay and administration (The Chartered Society of Physiotherapy, 2007). There is however no statistics documented on RSI’s among garment workers found for South Africa. Aim: To determine the prevalence of signs and symptoms of carpal tunnel syndrome and de Quervains tenosynovitis. Method: A study using quantitative data was used. A validated questionnaire consisting of open-ended and closed questions was utilized. Data was collected from two hundred subjects of varying age, gender and ethnic group. Information on signs and symptoms and possible risk factors of RSI’s were obtained. The visual analogue scale was used to assess pain, a goniometer to measure active range of movement, the Phalens test, Reverse Phalens test and Finkelsteins test was used to assess the signs and symptoms of the two occupational repetitive strain disorders. Data analysis: All data was captured and analysed using the Statistical Package for Social Sciences (SPSS version 15). Descriptive statistics such as mean, standard deviation, proportions, median, mode and interquartile range was used to summarize the data. Pearson’s Chi Square tests and Fishers Exact tests were used to test for association between two categorical variables. Independent Samples t-tests were used for the difference in age distribution between participants that presented with carpal tunnel syndrome and de Quervains tenosynovitis and of those who did not present with them. The level of significance was set at 0.05. Bar graphs, tables and pie charts were used to depict the results. Results/Discussion: The results of this study indicated that 59% of participants presented with signs and symptoms of de Quervains tenosynovitis and 63% of participants presented with signs and symptoms of carpal tunnel syndrome. The prevalence of carpal tunnel syndrome and de Quervains tenosynovitis was 42% and 43% respectively among garment workers in the eThekwini district. In addition, 100% of participants stated that they work under the following conditions, applying weight through the arms, repeated movement, work with their arms in unsupported positions, fast hand movements and holding or grasping for more than 2 hours continuously per day. Seventy two and a half percent of participants stated that their work entailed using vibratory tools for prolonged hours. Pearson’s Chi Square tests showed no association of use of vibratory tools to de Quervains tenosynovitis (P=0.666) or to carpal tunnel syndrome. This is inconsistent with the findings of the study completed by Leclerc et al. (1998) who stated that different dimensions of exposure to physical workload are widely recognised as risk factors. These risk factors include rapid hand motions, repetitive bending and twisting of the hands and the wrist, fast work pace, repetitive grasping with the fingers, mechanical stress at the base of the palm and the palm and the use of vibratory tools (Leclerc et al. 1998). Conclusion: This study has identified the prevalence of signs and symptoms of carpal tunnel syndrome and de Quervains tenosynovitis among garment workers. It has also shown that a significant percentage of garment workers presented with symptoms of burning, tingling, itching and numbness in their hands as well as feelings of swollen and ‘useless’ hands. A significant number presented with functional limitations to certain activities of daily living suggestive of the presence of carpal tunnel syndrome. De Quervains tenosynovitis was indicated when a significant number of participants presented with pain, tenderness or swelling over the radial aspect of the wrist as well as functional limitations to certain activities of daily living.

Upper body control is required to complete many daily tasks. One needs to stabilize the head and trunk over the pelvis, as one shifts the center of mass to interact with the world. While healthy individuals can perform activities that require leaning, reaching, and grasping readily, those with neurological and musculoskeletal disorders present with control deficits. These deficits can lead to difficulty in shifting the body center of mass away from the stable midline, leading to functional limitations and a decline in the quality of activity. Often these patient groups use canes, walkers, and wheelchairs for support, leading to occasional strapping or joint locking of the body for trunk stabilization. Current rehabilitation strategies focus on isolated components of stability. This includes strengthening, isometric exercises, hand-eye coordination tasks, isolated movement, and proprioceptive training. Although all these components are evidence based and directly correlate to better stability, motor learning theories such as those by Nikolai Bernstein, suggest that task and context specific training can lead to better outcomes. In specific, based on our experimentation, we believe functional postural exploration, while encompassing aspects of strengthening, hand-eye coordination, and proprioceptive feedback can provide better results. In this work, we present two novel cable robotic platforms for seated and standing posture training. The Trunk Support Trainer (TruST) is a platform for seated posture rehabilitation that provides controlled external wrench on the human trunk in any direction in real-time. The Stand Trainer is a platform for standing posture rehabilitation that can control the trunk, pelvis, and knees, simultaneously. The system works through the use of novel force-field algorithms that are modular and user-specific. The control uses an assist-as-needed strategy to apply forces on the user during regions of postural instability. The device also allows perturbations for postural reactive training. We have conducted several studies using healthy adult populations and pilot studies on patient groups including cerebral palsy, cerebellar ataxia, and spinal cord injury. We propose new training methods that incorporate motor learning theory and objective interventions for improving posture control. We identify novel methods to characterize posture in form of the “8-point star test”. This is to assess the postural workspace. We also demonstrate novel methods for functional training of posture and balance. Our results show that training with our robotic platforms can change the trunk kinematics. Specifically, healthy adults are able to translate the trunk further and rotate the trunk more anteriorly in the seated position. In the standing position, they can alter their reach strategy to maintain the upper trunk more vertically while reaching. Similarly, Cerebral Palsy patients improve their trunk translations, reaching workspace, and maintain a more vertical posture after training, in the seated position. Our results also showed that an Ataxia patient was able to improve their reaching workspace and trunk translations in the standing position. Finally, our results show that the robotic platforms can successfully reduce trunk and pelvis sway in spinal cord injury patients. The results of the pilot studies suggest that training with our robotic platforms and methods is beneficial in improving trunk control.

研究目的：脊髓損傷是中樞神經系統的嚴重創傷，致殘率高。脊髓損傷後的再生修復一直是當前醫學的難題。迄今為止，脊髓損傷依然缺乏一種有效地治療方法。既往研究證明，胰島素樣生長因子-1對鼠和兔脊髓損傷有保護作用，為了進一步把這些發現應用到臨床方面，我們採用與人類生理更相近的豬只作為實驗動物，構建與臨床相似的脊髓損傷動物模型，并以此為基礎，系統性研究胰島素樣生長因子-1的脊髓保護作用，評估該治療的功效。
研究方法：以運動誘發電位為指導，通過直接壓迫和牽拉造成脊髓損傷。18頭猪只隨機分為3組：胰島素樣生長因子-1治療組、生長激素治療組及生理鹽水對照組。脊髓損傷后1小時、24小時及48小時經鞘內注射給藥。于術後第1天、第3天及第21天收集腦脊液檢測胰島素樣生長因子-1和生長激素濃度。連續21天使用修正的 Tarlov 評分標準對動物的運動功能進行評估。第21天處死動物並取材，檢測脊髓中NeuN, GFAP, caspase-3 的活性，并通過TUNEL染色觀察細胞凋亡情況，比較各組之間有無差別。
研究結果：通過這種方法建立的脊髓損傷動物模型穩定可靠，各組之間無明顯差異。鞘內給藥24小時及48小時后，腦脊液中胰島素樣生長因子-1和生長激素濃度明顯升高，術後21天檢測，其濃度恢復至基礎值。胰島素樣生長因子-1治療組的運動功能的恢復優於其它各組。與生理鹽水對照組比較，胰島素樣生長因子-1治療組可以明顯提高脊髓損傷后神經元的存活數量，抑制星形膠質細胞增生，減少細胞凋亡。而生長激素治療組僅抑制星形膠質細胞增生，其它方面與生理鹽水對照組無明顯差別。
結論：胰島素樣生長因子-1通過提高神經元存活數量，抑制星形膠質細胞增生，以及減少細胞凋亡促進脊髓損傷的恢復。
Objective: Spinal cord injury is a devastating condition that leads to long-term disabilities. Currently, there is no effective treatment that minimizes spinal cord damage or enhances neurological recovery. Recent studies in rats or rabbits suggested that neurologic recovery after spinal cord injury could be improved with the administration of neurotropic hormones, such as insulin-like growth factor-1 (IGF-1). In order to apply such bench-side discovery to clinical practice, we conducted a study in a higher animal model, akin to human physiology, to evaluate the effectiveness of intrathecal injections of IGF-1to improve neurological recovery in a porcine model of acute traumatic spinal cord injury.
Methods: Traumatic spinal cord injury model was produced by controlled compression and distraction of the exposed T12 segment of the spinal cord. Eighteen pigs were randomly assigned to receive intrathecal injections of either IGF-1, growth hormone or saline at 1, 24 and 48 hours after spinal cord injury. Locomotor function was assessed daily using the validated modified Tarlov’s scale for 21 days. Spinal cord segments were then harvested and the survival of neurons, reactive astrogliosis and apoptosis were determined using neuronal-specific nuclear protein (NeuN), glial fibrillary acidic protein (GFAP), cleaved caspase-3 and terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) assays.
Results: Intrathecal injections of IGF-1 and growth hormone significantly increase the concentrations of the neurotropic hormones in the cerebrospinal fluid after injury (p < 0.01). These concentrations returned to baseline by 21 days after drug delivery. Motor deficits on the first day after injury were comparable between animals in the treatment and control groups. By the end of the third week, neurologic recovery was better in animals receiving IGF-1 treatment (p < 0.05). Immunohistological and western blot studies of the injured segments of spinal cord showed that treatment with both IGF-1 and growth hormone prevented reactive astrogliosis (p < 0.05) while only IGF-1 improved the survival of mature neurons (p < 0.05). IGF-1 also inhibited apoptosis after spinal cord injury (p < 0.05).
Conclusions: In our clinically relevant model of traumatic spinal cord injury in pigs, intrathecal injection of IGF-1 demonstrated beneficial effects on neurological and histological recovery.

This research study consisted of an examination of the role played by the educational psychologist in the emotional and social rehabilitation of the TBI adolescent. A survey of the literature reveals that traumatic brain injury during adolescence negatively impacts on their adaptation, development and functioning after the acute phase of the rehabilitation process. In order to study this phenomenon, a psycho-educational perspective was utilised. An in-depth qualitative study was undertaken by means of a case study design. The two cases being presented offers the reader insight into the cases pre-morbid functioning, the accident and its aftermath, the specific traumatic brain injuries, the emotional and social problems encountered by these adolescents as well as the psychotherapeutic interventions applied by the educational psychologist in the rehabilitation process of the cases under investigation. The conclusions reached from this investigation were that traumatic brain injury during the developmental phase of adolescence, negatively impacts on the emotional and social well being of these adolescents, and that the educational psychologist plays a valuable role in the emotional and social rehabilitation of these adolescents.

In this study an instrument is suggested for implementation by the Educational Psychologist to design a support programme, aimed at handling family members' stress where a child has sustained a brain injury. Attention was paid to the phenomenon "brain injured child" to ascertain demands and needs (physical, cognitive, psychological and emotional). Specific note was taken of the toll on each family member in their observance, experience, assistance and giving· meaning to the child. Reference was made to existing support programmes for such family members from the acute care phase to the final acceptance and readjustment of the family. With this study the need for a continuous support programme and the contents of such a programme was addressed. Using these guidelines the Educational Psychologist will be able to prepare the family for the stress possibilities in dealing with the brain injured child.
Met hierdie studie is 'n instrument daargestel vir die ontwerp van 'n hulpverleningsprogram vir gebruik deur die Opvoedkundige Sielkundige. Hierdie hulpprogram het as doel, die hantering van stres, deur die gesin van 'n kind, wat 'n breinbesering opgedoen het. In die studie is aandag gegee aan die tipiese gedrag wat oor die algemeen van 'n breinbeseerde kind verwag kan word. Daar is ook gepoog om te bepaal hoe elke lid van die gesin die breinbeseerde kind beleef, aan hom betekenis gee, en hom probeer help ten opsigte van die eise (fisiek en emosioneel) wat hy stel. Verder is daar gekyk na bestaande hulpverlening (gerig op die hantering van stres) aan die gesinslede van 'n breinbeseerde kind vanaf die akute versorgingsfase tot en met die aanpassing en herorganisering van die gesin. Met hierdie studie is 'n behoefte aan 'n kontinue hulpverleningsprogram en die inhoud van so 'n program by gesinslede aangespreek. Aan die hand van die riglyne sal die Opvoedkundige Sielkundige 'n gesin kan voorberei op die stres wat hulle ten opsigte van die hantering van 'n breinbeseerde kind te wagte kan wees.
