Academic literature on the topic 'Spinal cord Wounds and injuries Patients Rehabilitation Victoria'

OBJECTIVE Penetrating gunshot wounds (GSWs) to the spinal column are stable injuries and do not require spinal orthoses or bracing postinjury. Nonetheless, a high number of GSW-related spinal cord injury (SCI) patients are referred with a brace to national rehabilitation centers. Unnecessary bracing may encumber rehabilitation, create skin breakdown or pressure ulcers, and add excessive costs. The aim of this study was to confirm the stability of spinal column injuries from GSWs and quantify the overutilization rate of bracing based on long-term follow-up. METHODS This retrospective cohort study was performed at a nationally renowned rehabilitation center. In total, 487 GSW-related SCI patients were transferred for rehabilitation and identified over the last 14 years. Retrospective chart review and telephone interviews were conducted to identify patients who were braced at the initial treating institution and determine if late instability, deformity, or neurological deterioration resulted in secondary surgery or intervention. In addition, 396 unoperated patients were available for analysis after 91 patients were excluded for undergoing an initial destabilizing surgical dissection or laminectomy, thereby altering the natural history of the injury. All of these 396 patients who presented with a brace had bracing discontinued upon reaching the facility. RESULTS In total, 203 of 396 patients were transferred with a spinal brace, demonstrating an overutilization rate of 51%. No patients deteriorated neurologically or needed later surgery for spinal column deformity or instability attributable to the injury. All patients had stable injuries. The patterns of injury and severity of neurological injury did not vary between patients who were initially braced or unbraced. The average follow-up was 7.8 years (range 1–14 years) and the average age was 25 years (range 10–62 years). CONCLUSIONS The incidence of brace overutilization for penetrating GSW-related SCI was 51%. Long-term follow-up in this study confirmed that these injuries were stable and thus did not require bracing. No patients deteriorated neurologically, whether or not they were initially braced. The unnecessary use of spinal orthoses increases costs and patient morbidity. Reeducation and dissemination of this information is warranted.

Many soldiers who were wounded during the war in Ukraine with Russia increased the number of cases of spinal injury. As a result of the Russia-Ukraine war, the number of patients with spine and spinal cord injuries increased significantly. According to the literature, gunshot wounds to the spine and spinal cord accounted for 0.26% of all soldier injuries during the American Civil War, with a mortality rate of 55%. According to the U.S. military data, spinal and spinal cord injuries accounted for 1.2% of war-related deaths during the Korean War, 1.0% - during the Vietnam War and the Gulf War, 6.0% - during the US invasion of Panama, 11.1% - during the war in Afghanistan and Iraq. Disability related to spinal cord injuries (14.0%) is currently the leading cause of discharge from military service for U.S. soldiers who have been injured. Patient M., 32 years old, male sustained mine blast injury. Immediately after the injury there was tetraplegia. Surgery was performed to correct vertebrae С7–Тh1, decompression of the spinal cord at the level of vertebrae С7–Тh1. Sixteen days after surgery, the neurological deficit regressed to the Frankel C clinical group. The patient was transferred to rehabilitation treatment. A clear, consistent, rapid algorithm of action in spinal cord injuries allowed to provide highly qualified care, which allowed to achieve significant results in the regression of neurological deficits in the postoperative period.

IntroductionPhysical Medicine and Rehabilitation is a goal oriented and patient centered specialty which focuses on functional restoration and quality of life of persons with disability. The patterns of injuries among survivors of recent disasters have, range from mild (single limb fracture) to catastrophic (spinal cord injury, amputation, traumatic brain injury). Historically physiatrists have not participated the acute disaster management phase or in the emergent post disaster rehabilitation planning. This task is usually relegated to the trauma, orthopedic and general surgeons.MethodologyAuthors had firsthand experience in the acute and emergent care and rehabilitation of trauma patients after Pakistan, China and Haiti earthquakes. An electronic literature search (English, 1965–2010, Key words: trauma, rehabilitation, disability, spinal cord injury, amputation, disaster, nerve injury) was carried out. Experience sharing through committees, online forum, and communications were conducted with physiatry colleagues internationally.ResultsIn these three recent earthquakes, Physiatrists provided direct patient care, including guidance in the evacuation of survivors with pre-existing disabilities, transport of persons with spinal trauma, treatment of wounds, fractures, pain, spinal trauma patients and persons with amputations. Physiatrists devised appropriate plans for conservative management of fractures. Education of local staff and coordination of rehabilitation was initiated. Monitoring, prevention and treatment of secondary complications including prolonged immobility, pressure ulcers, chronic pain, urinary, bowel and respiratory dysfunction was performed. Physiatrists helped in patient counseling and family education.ConclusionPhysiatrists by virtue of their training and skills are in a better position to manage the disabilities, including direction of rehabilitation and community integration, prevention of complications, and education and training of health workers and teams. Timely rehabilitation interventions for Spinal cord injuries and lower limb amputations following the Pakistan, China and Haiti earthquakes resulted in reduction in morbidity and mortality among those with catastrophic injuries.

Background: Epidemiological features of spinal cord injury (SCI) have been changing over the last decades. We evaluated the contemporary trends in the epidemiology of traumatic SCI patients from a rehabilitation center. Methods: In a cross-sectional study, a consecutive series of 348 patients with traumatic SCI were evaluated. Variables were collected through an epidemiological form, which included gender, age at injury, duration and cause of SCI. We investigated SCI epidemiological trends over time including the association between gender and age at injury with SCI features such as etiology, injury severity and level. Results: The mean age at SCI has increased from 26.0 ± 11.8 in patients with SCI before 2003 to 37.9 ± 15.7 in those with SCI after 2009 (p < 0.001). Gunshot wounds were the main cause of injury in patients with SCI before 2003, dropping from 40.6 to 16.9% after 2009 and being surpassed by road traffic injuries (38.6%) and falls (31.4%) after 2009 (p < 0.001). Gender, SCI severity and level have not changed significantly over the time. Conclusions: There was a major increase in the average age of patients as well as changes in the etiology of SCI over the past fifteen years, including a significant decrease in gunshot wounds and an increase in the frequency of road traffic injuries and falls. These changes and accompanying risk factors must be taken into consideration when planning measures to prevent SCI.

Spinal cord injury (SCI) patients have a higher risk of developing pressure injury secondary to limited mobility and lack of sensation. The James J Peters Medical Center is one of several regional spinal cord injury centres in the Veterans Affairs System. Veterans with SCI receive comprehensive care. Hospital- and community-acquired pressure injuries (HAPIs and CAPIs) can progressively advance to chronic stage IV pressure injury complicated with osteomyelitis. Chronic wounds that become infected can lead to sepsis if the wounds are not managed properly. The management of chronic wounds represents a significant financial burden for any health care system and a challenge for providers whose goals are to avoid prolongation of hospital stay, avoid complications, and minimise disruption in the patient’s life. A focus of the primary physician is to establish a rehabilitation plan that facilitates the patient to resume activities of daily living post injury and have a productive life in their community. However, despite the collaborative effort of the SCI team, the sudden change in the patient’s mobility can also have a detrimental impact on the patient’s mental status as well.

Introduction Cervical spinal cord injury (CSCI) is a significant medical and socioeconomic problem. In Victoria, Australia, there has been limited research into the incidence of CSCI. The Austin Hospital's Victorian Spinal Cord Injury Service (VSCIS) is a tertiary referral hospital that accepts referrals for surgical management and ongoing neurological rehabilitation for south eastern Australia. The aim of this study was to characterise the epidemiology of CSCI managed operatively at the VSCIS over the last decade, in order to help fashion public health campaigns. Methods This was a retrospective review of medical records from January 2000 to December 2009 of all patients who underwent surgical management of acute CSCI in the VSCIS catchment region. Patients treated non-operatively were excluded. Outcome measures included: demographics, mechanism of injury and associated factors (like alcohol) and patient neurological status. Results Men were much more likely to have CSCI than women, with a 4:1 ratio, and the highest incidence of CSCI for men was in their 20s (39%). The most common cause of CSCI was transport related (52%), followed by falls (23%) and water-related incidents (16%). Falls were more prevalent among those >50 years. Alcohol was associated in 22% of all CSCIs, including 42% of water-related injuries. Discussion Our retrospective epidemiological study identified at-risk groups presenting to our spinal injury service. Young males in their 20s were associated with an increased risk of transport-related accidents, water-related incidents in the summer months and accidents associated with alcohol. Another high risk group were men >50 years who suffer falls, both from standing and from greater heights. Public awareness campaigns should target these groups to lower incidence of CSCI.

This was a descriptive cross-sectional study on patients with spinal cord injuries living in Curitiba, Paraná, Brazil. The aim was to evaluate the pain characteristics among such patients seen at referral care centers for spinal cord injury patients in Curitiba. A total of 109 adults with spinal cord injury in this city were evaluated regarding the presence of pain, especially neuropathic pain. Neuropathic pain was evaluated using the DN4 questionnaire, a universal instrument that has been translated and validated for Portuguese. A visual analog scale (VAS) was used to evaluate the intensity of pain. The prevalence of pain among these 109 patients was 31.2% (34 patients). The nociceptive pain presented was classified as musculoskeletal pain (nine patients), visceral pain (four patients) and mixed pain (one patient), thus totaling 14 patients (12.8%). Another 20 patients (18.3%) showed symptoms of neuropathic pain and fulfilled the criteria for neuropathic pain with scores greater than 4 out 10 in the DN4 questionnaire. Regarding the characteristics of the patients with neuropathic pain, most of them were male, younger than 40 years of age and paraplegic with incomplete lesions. They had become injured from 1 to more than 5 years earlier. The predominant etiology was gunshot wounds, and the intensity of their pain was high, with VAS scores greater than 5. This study partially corroborates other studies conducted on this subject. Studies of this type are important for understanding the profile of these patients, for the purpose of designing strategies for their rehabilitation, with a focus on the appropriate treatment and management of pain.

BackgroundSince 2011, hundreds of thousands of Syrians have been displaced and injured due to the ongoing Syrian civil war. In this study, we report the prevalence of neurologic injuries in a major rehabilitation center on the Turkish–Syrian border where death and injury tolls continue to rise.MethodBased on several on-site visits from 2013 to 2016, medical practitioners collected data from patients in the major rehabilitation center on the border of Turkey and Syria. The clinical data, which included the type and cause of injury, laterality, paralysis, areas injured, and treatment offered, were analyzed.ResultsA total of 230 patients were identified as having sustained a neurologic injury, 221/230 (96.1%) male and 9/230 (3.91%) female, ranging from ages 2–52 years. A total of 305 total injuries were documented over the course of a 4-year analysis due to several patients having multiple injuries. Gunshot wounds were the dominant mechanism of injury in 125/230 (54.3%) patients. Patients more frequently sustained single injuries 152/230 (66.1%) than multiple injuries 78/230 (33.9%). Peripheral nerve injuries were the most prevalent injuries, at 92.5% of all neurologic injuries (282/305), specifically injury to the radial nerve, at 19.1% (54/282) of peripheral injuries. Patients with spinal cord injuries made up 20/230 (8.7%) of all patients, with thoracic spine injuries composing 50% (10/20). Traumatic brain injuries were the least prevalent, 3/230 (1.3%), with an equal distribution of subtypes.ConclusionThis study and critical analysis of the devastation in Syria suggests the desperate need for emergency aid.

During the first half of the 19th century, warfare did not provide a background for a systematic analysis of spinal cord injury (SCI). Medical officers participating in the Peninsular and Crimean Wars emphasized the dismal prognosis of this injury, although authors of sketchy civil reports persuaded a few surgeons to operate on closed fractures. The American Medical and Surgical History of the War of the Rebellion was the first text to provide summary of results in 642 cases of gunshot wounds of the spine. The low incidence of this injury (0.26%) and the high mortality rate (55%) discouraged the use of surgery in these cases. Improvements in diagnoses and the introduction of x-ray studies in the latter half of the century enabled Sir G. H. Makins, during the Boer War, to recommend delayed intervention to remove bone or bullet fragments in incomplete injuries. The civil experiences of Elsberg and Frazier in the early 20th century promoted a meticulous approach to treatments, whereas efficient transport of injured soldiers during World War I increased the numbers of survivors. Open large wounds or cerebrospinal fluid leakage, signs of cord compression in recovering patients, delayed clinical deterioration, or intractable pain required surgical exploration. Wartime recommendations for urological and skin care prevented sepsis, and burgeoning pension systems provided specialized long-term rehabilitation. By the Armistice, the effective surgical treatment and postoperative care that had developed through decades of interaction between civil and military medicine helped reduce incidences of morbidity and dispel the hopelessness surrounding the combatant with an SCI.

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.

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.

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.

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.

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.

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.

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.
