BackgroundSocial media presents an important means for social interaction, especially among adolescents, with Instagram being the most popular platform in this age-group. Pictures and communication about non-suicidal self-injury (NSSI) can frequently be found on the internet.MethodsDuring 4 weeks in April 2016, n = 2826 (from n = 1154 accounts) pictures which directly depicted wounds on Instagram were investigated. Those pictures, associated comments, and user accounts were independently rated for content. Associations between characteristics of pictures and comments as well as weekly and daily trends of posting behavior were analyzed.ResultsMost commonly, pictures depicted wounds caused by cutting on arms or legs and were rated as mild or moderate injuries. Pictures with increasing wound grades and those depicting multiple methods of NSSI generated elevated amounts of comments. While most comments were neutral or empathic with some offering help, few comments were hostile. Pictures were mainly posted in the evening hours, with a small peak in the early morning. While there was a slight peak of pictures being posted on Sundays, postings were rather evenly spread across the week.ConclusionsPictures of NSSI are frequently posted on Instagram. Social reinforcement might play a role in the posting of more severe NSSI pictures. Social media platforms need to take appropriate measures for preventing online social contagion.

Objective: Children are at high risk of injuries and wounds. The application of medical grade honey is a promising approach to improving the healing of wounds of various origin and severity. However, the use of medical grade honey in young paediatric patients remains limited. The aim of this study is to show the safety, efficacy and usefulness of medical grade honey in abdominal wounds, of different causes, in paediatric patients. Method: This was a prospective, observational case series evaluating five young infants with abdominal wounds at the General Hospital in Thessaloniki. All wounds were treated in the same manner with daily medical grade honey applied to the wound area and closely monitored. Results: All treated wounds rapidly presented granulation tissue formation and underwent re-epithelialisation. Peripheral oedema and inflammation decreased upon initial application. Necrotic tissue was effectively debrided when present. Slough was removed and no signs of infection were detected, irrespective of initial wound presentations. Scar formation was minimal and the full range of motion was preserved in all cases. Conclusion: Based on this case study, medical grade honey is safe and effective in treating different abdominal wounds, including infected or dehisced wounds as well as burns. The easy application and broad applicability make medical grade honey recommendable as a first-line treatment in paediatric patients.

Background. Hot-crush injuries to the hands can be devastating, and early debridement and coverage with skin autograft remains the golden standard of wound treatment. However, this type of treatment is not feasible or unlikely to succeed due to limited donor sites and wound characteristics of hot-crush injuries on hands. Thus, the composite grafting of acellular dermal matrix (ADM) and split-thickness skin graft (STSG) as a novel alternative method has been attempted. In this series, the results are presented to demonstrate the feasibility and effectiveness of the use of one-stage procedure for early reconstruction in hand hot-crush injuries. Methods. All consecutive patients with hand hot-crush injuries, who underwent one-stage procedure of ADM and ultrathin STSG for soft tissue coverage at our institution from December 2018 to November 2019, were retrospectively analyzed. Wound dressings were opened on 7 days after operation to examine graft survival and complications. Patients were followed up for at least 9 months to evaluate their hand profiles. Results. Samples of 14 patients with a total of 23 wounds were involved in the study. Thirteen of the 23 third–fourth-degree wounds had varying degrees of tendon exposure. On 7 days postoperation, the composite grafts survived in 12 patients with minimal focal graft losses and liquefaction and necrosis in 2 patients, which achieved successful healing following new coverage of ultrathin STSG. All the wounds healed with hospital stays ranging from 9 days to 32 days (median: 24.5 days). At the final follow-up (from 9 months to 20 months), all patients achieved excellent or good total active motion grade and good scar quality (Vancouver scar scale scored 1–3) with no revision surgery. Conclusions. One-stage composite grafting of ADM and ultrathin STSG is a reliable alternative for early reconstruction in hand hot-crush injuries, which delivers good functional outcomes and a good cosmetic appearance.

Introduction: The hand is a very important body part with complex anatomy. Important neurovascular structures are located in the hand. Many superficial injuries of the hand, which may at first glance appear harmless, are often associated with injuries to tendons, nerves, and blood vessels. This paper describes soft tissue injuries, while injuries to the bone have been excluded from the study. Aim: The aim of this study is to present the functional outcome of the treatment of patients with soft tissue wounds to the volar aspect of the wrist. Methods: A retrospective analysis of 20 patients treated at the Microsurgery Department of the Emergency Center in Belgrade was performed. We observed the following: gross grip strength (GGS) of the hand, range of motion, the two-point discrimination test (2PD), while the patients filled out the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. Results: In our study, the GGS of the injured hand was 80.9% of the strength of the uninjured hand. The mean range of motion of the wrist, as well as of the DIP, PIP, and MCP joints, ranged from 77.45% to 91.6%, as compared to the uninjured hand. An S3+ level of sensory recovery was achieved by 10% of patients. The average DASH score was 19.78. Conclusion: Our study shows that proper and timely treatment is necessary for a good functional result in the treatment of these injuries.

Abstract Background Full-thickness injuries to the hand require durable soft tissue coverage to preserve tendon gliding and hand motion. We aim to investigate the cost effectiveness of hand resurfacing comparing free fascial flap reconstruction versus bilaminate synthetic dermal matrices. Methods Cost effectiveness was modeled using decision tree analysis with the rollback method. Total active range of motion was modeled as the common outcome variable based on systematic literature review. Costing was performed from a payer perspective using national Medicare reimbursements. The willingness to pay threshold was determined by average worker's compensation for hand disability. Probabilistic sensitivity analysis was conducted for range of motion outcomes and the costs using 10,000 Monte Carlo simulations. Results The average cost of free fascial flap reconstruction was $14,201.24 compared with $13,674.20 for Integra, yielding an incremental cost difference of $527.04. Incremental range of motion improvement was 18.0 degrees with free fascial flaps, yielding an incremental cost effectiveness ratio of $29.30/degree of motion. Assuming willingness to pay thresholds of $557.00/degree of motion, free-fascial flaps were highly cost effective. On probabilistic sensitivity analysis, free fascial flaps were dominant in 25.5% of simulations and cost effective in 32.1% of simulations. Thus, microsurgical reconstruction was the economically sound technique in 57.5% of scenarios. Conclusion Free fascial flap reconstruction of complex hand wounds was marginally more expensive than synthetic dermal matrix and yielded incrementally better outcomes. Both dermal matrix and microsurgical techniques were cost effective in the base case and in sensitivity analysis. In choosing between dermal matrix and microsurgical reconstruction of complex hand wounds, neither technique has a clear economic advantage.

Seventeen patients with open fractures of the upper third of the femur were treated using a pelvifemoral external fixation device. All of them had grade III open fractures resulting from high-velocity missile and explosive injuries with massive foreign body contamination. Sciatic nerve injury was present in five (29.4%); abdominal viscera and thoracic wall injuries were present in two patients (11.8%). There were no major arterial injuries. Full weight bearing was allowed after clinical and radiological bone healing (average 11.5 months). Chronic osteitis with fistula and sequestra developed in two (11.8%) patients. There were no nonunions and no refractures. Minor painless limitation of hip motion persisted in all patients. Upper-third femoral open fractures due to firearms are a unique type of open fractures. They are usually highly comminuted ; therefore, stable fixation is difficult or impossible to achieve using external fixation with transfixation of the fracture site. On the other hand, the risk of infection is high following intramedullary nailing. Pelvifemoral external fixation allows adequate management of the soft tissue wounds, provides stable bone fixation and allows early patient mobilization.

Introduction: High energy proximal tibia fractures with soft tissue involvement presenting with dicolored patches over the leg and severe swelling, compound wounds, blisters with tight compartments and absent or feeble dorsalis pedis or posterior tibial arteries warrant to go in for a staged procedure. In patients with multiple injuries, an external fixator can be applied quickly with minimal blood loss for unstable periarticular fractures around the knee. Two-stage procedures involve (1) early joint spanning external fixators with fasciotomy for the medial and posterior compartments, (2) and late definitive fixation with plates or nails and with skin grafting. Materials and Methods: In our study, we present a short series of 15 proximal tibial fractures with impending compartment syndrome. Patients selected for this study were (1) closed proximal tibia fracture intra- and peri-articular and metaphysis diaphysis junction communited and noncommunited fractures (2) impending compartment syndrome evaluated based on excessive swelling, tight compartments, blisters over skin, feeble or absent dorsalis pedis or posterior tibial pulsations, color Doppler suggestive of severe subcutaneous edema associated with monophasic or absent flow over distal arteries. Exclusion criteria: (1) Low energy proximal tibia fracture without soft tissue insult and compound wounds over the proximal tibia fractures, (2) associated popliteal artery injuries. Conclusion: With the initial application of a bridging external fixator followed by delayed internal fixation protocol for pilon fractures has been successful in reducing the historically high rates of wound complications associated with these high-energy injuries. As well this protocol allows the use of minimally invasive plate osteosynthesis technique which is based on a combination of the principles of stability, restoration of anatomy and early motion while eliminating the need for excessive soft tissue dissection.

Edward Muybridge was an Anglo-American photographer, well known for his pioneering contributions in photography and his invention of the “zoopraxiscope,” a forerunner of motion pictures. However, this 19th-century genius, with two original patents in photographic technology, made outstanding contributions in art and neurology alike, the latter being seldom acknowledged. A head injury that he sustained changed his behavior and artistic expression. The shift of his interests from animal motion photography to human locomotion and gait remains a pivotal milestone in our understanding of patterns in biomechanics and clinical neurology, while his own behavioral patterns, owing to an injury to the orbitofrontal cortex, remain a mystery even for cognitive neurologists. The behavioral changes he exhibited and the legal conundrum that followed, including a murder of which he was acquitted, all depict the complexities of his personality and impact of frontal lobe injuries. This article highlights the life journey of Muybridge, drawing parallels with Phineas Gage, whose penetrating head injury has been studied widely. The wide sojourn of Muybridge also illustrates the strong connections that he maintained with Stanford and Pennsylvania universities, which were later considered pinnacles of higher education on the two coasts of the United States.

Abstract Introduction Burn survivors face long and often painful rehabilitation after injury. Unfortunately, the severe pain from burn injuries can lead to chronic pain and stress-related disorders. Occupational therapists work with burn survivors to improve movement and reduce negative impacts of scars to increase independence with self-care tasks, return to work and hobbies, and facilitate social participation. Paraffin wax is used as a modality by occupational therapists to decrease pain and assist with soft issue mobilization. It is imperative to determine if paraffin is beneficial specifically for burn injuries to facilitate physiological and psychological recovery. Methods Low melting point paraffin wax at a temperature between 120-130 degrees without scent was chosen to prevent any burns or allergic reactions. Inclusion criteria was for subjects over the age of 18 years and all wounds on extremity being assessed must have been closed. Active range of motion (AROM) and passive range of motion (PROM) were assessed as well as pain score. The patient then washed the extremity with soap and water, dried, placed into the paraffin bath, dipped four times, then placed into a plastic liner and wrapped in a towel for 10 minutes. After the treatment was complete, ROM and pain were assessed and the patient was offered an opportunity to provide any feedback or comments. Results A total of 7 burn survivors were identified and chosen for participation in the study. All patients showed improvement of AROM and PROM measurements of the tested extremity. Pain was reduced with every patient by an average of 30%. Every patient reported less pain and better movement, subjectively. Most patients reported less fear or anxiety. 42% of patients felt like their scar was softer after the paraffin treatment. Unfortunately, the study has a limited trial size due to requirement of completely closed wounds with continued follow up by the patient in clinic. Many patients with closed wounds do not follow up in the clinic on a regular basis. Interestingly, women reported more psychological benefits and also more likely to report a plan to continue using paraffin at home, compared to the men. AROM and PROM improved consistently within each session after paraffin was used, however week to week improvement was more variable between patients. This could be due to varying compliance of each individual’s home exercise program. Conclusions Paraffin wax can be beneficial during occupational therapy for soft tissue mobilization of burn scars to increase range of motion and reduce pain and anxiety. Utilizing paraffin wax as a modality helps to reduce physiological and psychological barriers of traditional occupational therapy interventions and should be considered as an adjunct treatment. Applicability of Research to Practice While the use of paraffin has been studied for treating conditions such as arthritis, scleroderma, and stroke, there is limited research on the use of paraffin for treating burn scars.

Research shows that up to 80% of recreational skiers have lower limb alignments which can impede their ability to turn their skis properly (Subotnick,1982). The most difficult of these alignment problems to control within a ski-boot is the varus alignment of the subtalar joint (Macintyre and Matheson, 1988). The use of custom molded footbeds made specifically for use inside of ski boots has been suggested as one method of compensating for a varus aligned foot. This study compared the effectiveness of one brand of custom molded ski boot footbed with that of a noncustom
insole in controlling the motions of the lower limb associated with subtalar varus. Specifically these motions were those of the rearfoot and the navicular tubercle, along with the alignment of the tibial tuberosity with respect to the mid-line of the ski boot. In addition, subjects were given the opportunity to assess their subjective feelings of edge control, pain, and fatigue while skiing with both the custom molded footbeds and non-custom insoles.
The subject group for this study consisted of 13 advanced level adult skiers who demonstrated more than three degrees of subtalar varus when non-weight bearing. Each subject received a pair of custom molded ski boot footbeds at the beginning of the study.
Ski boots that had been cut away at the rear and the medial side were used in the laboratory in order to observe the motions of the navicular tubercle and the rearfoot as the subject transferred their weight in a simulated skiing motion.
The right and left navicular tubercle, tibial tubercle, and the insertion of the Achilles at the calcaneus of each subject were located by palpation and marked. After sufficient practice of the weight transfer motion, two trials of each landmark were photographed using 35mm slide film. The subjects were first photographed while using the non-custom insoles and again using the custom molded footbeds. The slides were digitized and comparisons were made between the two types of insoles for both the start and end locations of the landmarks as well as for the ranges of motion through which the landmarks traveled.
Statistical analyses of the group results indicated that there was significantly less (p=0.000) navicular motion during the shift from the start to the end positions with the use of the custom molded footbeds as compared to the non-custom insoles. The rearfoot angle was significantly less at both the start (p=0.000) and end (p=0.000) positions with the use of the custom footbeds as compared to the noncustom
insoles. There was no statistical difference between the amount of rearfoot motion allowed by either type of insole. The tibial tubercle was positioned significantly (p=0.000) closer to the mid-line of the ski boot when using the custom footbeds than with the use of the non-custom insoles. These results indicate that the custom footbeds domaintain the subtalar joint in a more neutral position than do non-custom insoles.
During the skiing section of the study the subjects rated the custom footbeds as providing better edge control (p=0.000) and resulting in less fatigue (p=0.000) than noncustom
insoles. There was no statistical significance when comparing the ratings given by the group for the level of pain experienced with the use of either type of insole. There was a statistically significant improvement (p=0.000) in race times for the group when using the custom footbeds as compared to the non-custom insoles.
The results of this study indicate that custom molded ski boot footbeds are able to control subtalar motion more effectively than a non-custom insole. It appears that this control of subtalar motion enhances the skiing experience by increasing edge control and reducing the amount of fatigue experienced.Education, Faculty of

The purpose of this study was to compare the protective characteristics of four different ankle braces and one form of ankle taping. An inversion and plantar flexion platform was used to induce ankle movements. The subjects used in this study consisted of 10 volunteer male students. The subjects had no sprains five months prior to testing. All subjects were tested in the same size 10 shoes, high tops and low tops. A Certified Athletic Trainer applied all ankle braces and ankle tapings. A closed basketweave with heel locks, adherent spray, and pre-wrap was used for all taping conditions.After the application of the ankle braces or taping, each subject performed two tests on the inversion and plantar flexion platform. A random order was used among the subjects. An ankle inversion platform was modified to induce 30 degrees of inversion and 35 degrees of plantar flexion simultaneously. The subjects will be filmed using a Locam 16mm at 200 frame/second. All subjects were filmed from the posterior plane with markings on the posterior aspect of the lower leg to help analyze the movement at the subtalar joint. A Calcomp 9100 series digitizer that was interfaced with a VAX computer was used to analyze the data and calculate the amount of angular displacement at the subtalar joint. An ANOVA with repeated measures was used to determine significant differences between support techniques. University procedures for the protection of human subjects was followed. ANOVA procedures indicated no significant difference in angular displacement between braces. A statistical analysis indicated that low top shoes provided significantly more support than high top shoes in braced ankles.School of Physical Education

Lower Back Disorders account for 16-19% of work related claims and 33-41% of dollars paid in workers? compensation (as cited in Marras, 1999), with impacts to society approaching $100 billion dollars annually (as cited in Marras et al., 1999). Dr. William Marras engineered a device to track trunk kinematics in order to develop a Job Risk Classification Model for predicting high-risk group probability of lower back injury. The device has been validated, but other technologies such as 3-D motion capture can potentially gather the same data. This study examined the use of motion capture to apply two- and three-plane lifting tasks to the Marras model and compare results with commonly used assessment techniques. Regardless of the fact that the Marras model results were drastically different from NIOSH and RULA, motion capture was able to gather all necessary data for running the models and has a promising future in ergonomic assessments.

Glial cells maintain homeostasis that is essential to neuronal function. Injury to the nervous system leads to the activation and proliferation of glial cells and pericytes, which helps to wall off the damaged region and restore homeostatic conditions. Sonic hedgehog is a mitogen which is implicated in injury-induced proliferation of glial cells and pericytes. The mitogenic effects of sonic hedgehog require primary cilia, but the few reports on glial or pericyte primary cilia do not agree about their abundance and did not address effects of injury on these cilia. Primary cilia are microtubule-based organelles that arise from the centrosome and are retracted before cells divide. Depending on cell type, proteins concentrated in cilia can transduce several mitotic, chemosensory, or mechanosensory stimuli. The present study investigated effects of stab wound injury on the incidence and length of glial and pericyte primary cilia in the area adjacent to the injury core.
Astrocytes, polydendrocytes and pericytes were classified by immunohistochemistry based on cell-type markers. In normal adult mice, Arl13b immunoreactive primary cilia were present in a majority of each cell type examined: astrocytes, 98±2%; polydendrocytes, 87±6%; and pericytes, 79±13% (mean ± SEM). Three days post-injury, cilium incidence decreased by 24% in astrocytes (p< 0.008) and 41% in polydendrocytes (p< 0.002), but there was no significant effect in pericytes. Polydendrocytes labeled with the cell cycle marker Ki67 were less likely to have cilia compared to resting, Ki67- polydendrocytes. Considering post-injury rates of proliferation for astrocytes and polydendrocytes, it appears that resorption of cilia due to cell cycle entry may account for much of the loss of cilia in polydendrocytes but was not sufficient to account for the loss of cilia in astrocytes. Under normal conditions, astrocytes rarely divide, and they maintain non-overlapping territories. However, three days after injury, there was a 7-fold increase in the number of paired mirror-image astrocytes (p< 0.018), which are most likely daughter cells from astrocytes that recently divided. Cilia incidence tended to decrease in these pairs compared to single astrocytes (p< 0.057) in injured mice. This is the first systematic investigation of cilia of astrocytes, polydendrocytes, and pericytes in the brain. Moreover, the examination of effects of brain injury on cilia adds to the understanding of injury-induced proliferation in these cells.

Dissertation submitted in partial compliance with the requirements for a Master's Degree in Technology: Chiropractic, Durban University of Technology, 2010.Motion palpation is used to assess the functional status of a joint and is defined as “The manual palpation of bony structures and soft tissues, through pressure applied in various directions of joint motion to ascertain areas of joint hypomobility and hypermobility.” Motion palpation is a collection of manual examination procedures, used to identify the site and characteristics of altered joint motion and which has been an important part of chiropractic since its inception. One of the most important goals for any clinical instrument is for it to have good reliability and reproducibility, this is because the clinical value of a test must be demonstrated before the results are considered valid. The extent to which a repeated test will produce the same result when evaluating an unchanged characteristic is its reliability. Reliability is evaluated by multiple blinded measurements performed on a sample of subjects. Inter-examiner reliability evaluates the consistency of different examiners and is determined through repeated assessment by two or more raters. Objective The aim of this study was to determine the inter-examiner reliability of motion palpation of knee joints with patellofemoral pain syndrome and asymptomatic knee joints, and to compare the inter-examiner reliability of motion palpation between the two groups. Method This quantitative, inter-examiner, clinical reliability study, included 30 patients each with one knee with patellofemoral pain syndrome and one asymptomatic knee. Each patient had both of their knees motion palpated by three independent examiners blinded to which was the symptomatic knee. The examiners were senior student interns at the DUT Chiropractic Clinic. The motion palpation findings were recorded and statistically analyzed through the SPSS statistical package. Fleiss Kappa statistic was used to give a Kappa score for each direction of motion palpation and these scores evaluated the inter-examiner reliability of motion palpation in the symptomatic and the asymptomatic knee. A comparison of the inter-examiner reliability of motion palpation between the two groups was performed using a paired Wilcoxin signed ranks test. Results The Kappa scores for motion palpation ranged from -0.2081 to 0.1802 for the symptomatic knee joint and -0.2836 to 0.0339 for the asymptomatic knee. This shows poor agreement in both cases. There was no significant difference in Kappa values (p= 0.609) for the two groups for the Wilcoxin signed ranks test and the number of positive and negative ranks were similar. This indicates that the reliability of motion palpation in both groups was similar. Conclusion It was concluded that inter-examiner reliability of motion palpation of the knee joint was poor in knees with patellofemoral pain syndrome and in knees that were asymptomatic. Motion palpation was found to be equally reliable in both groups, indicating that motion palpation of a symptomatic joint does not improve its reliability. This research suggests that motion palpation should be used together with other diagnostic tests to identify patellofemoral pain syndrome as it is not a reliable tool when used in isolation.

Master’s Degree in Technology: Chiropractic, Durban University of Technology, 2010.Motion palpation is an examination technique commonly used by chiropractors to identify a manipulable subluxation prior to manipulation. In order for its continued use, it must be validated. Many studies conducted on motion palpation’s inter-examiner reliability in the spine have shown it to be below average, however only a few studies have addressed its use in the extremity joints. No inter-examiner reliability studies on motion palpation were found for the elbow, let alone the symptomatic elbow with regards to chronic lateral epicondylalgia, a common disorder of the elbow effectively treated by the use of manipulation. Objectives The objectives of this study were to determine the inter-examiner reliability of motion palpation of the elbow for the asymptomatic elbow and the symptomatic elbow with regards to chronic lateral epicondylalgia. It also aimed to compare these results to determine any difference in reliability, the number of manipulable subluxations and the presence of manipulable subluxations in particular directions, between the two groups. Method Twenty participants (n=40 elbows) between the ages of 18 to 65, with one asymptomatic and one symptomatic elbow (chronic lateral epicondylalgia) were examined by three final year masters chiropractic students for the presence of manipulable subluxations in end play, using only motion palpation. The examiners were pre-trained, randomised and blinded. Each examiner individually motion palpated both elbows on each participant, in nine directions of motion palpation, incorporating the humeroulnar and proximal radioulnar joints. They were also required to identify which elbow was symptomatic. Fleiss’ kappa and percentage agreement (perfect percentage agreement and mean percentage agreement) were used to measure reliability. Paired non parametric Wilcoxon signed ranks compared the difference between both groups and McNemar’s chi square tests assessed the percentage of correctly identified symptomatic elbows for each examiner. A p value <0.05 was considered statistically significant. iv Results The asymptomatic elbows showed a poor range of kappa results, from 0.0683 to -0.1321, with a mean kappa of -0.0664. Perfect percentage agreement was 50% to 85% and mean percentage agreement was 83.30% to 94.99%. The symptomatic elbows’ kappa values ranged between -0.2691 to 0.4034 with a mean kappa of -0.0028. The humeroulnar medial to lateral direction of motion palpation had a moderate kappa value of 0.4034. Perfect percentage agreement ranged from 10% to 85% and mean percentage agreement from 69.94% to 94.99%. There was an insignificant difference in kappa values between the two groups (p=0.260), although there was a trend towards the asymptomatic kappa values being lower than the symptomatic values. The difference between symptomatic and asymptomatic elbows was significant in proximal radioulnar posterior to anterior glide in pronation (p=0.013), as well as proximal radioulnar rotation of the radial head on the ulna (p=0.008). Overall, more manipulable subluxations were found in the symptomatic elbows than in the asymptomatic elbows. The examiners correctly identified the symptomatic elbow in 65% to 90% of participants (p=1.000). Conclusions and Recommendations In conclusion, the inter-examiner reliability of motion palpation in the asymptomatic elbow was poor, and in the symptomatic elbow (chronic lateral epicondylalgia), poor to moderate. There was an insignificant difference in reliability between the two groups, although more manipulable subluxations were found in the symptomatic elbows overall. These were mainly in proximal radioulnar posterior to anterior glide in pronation, as well as proximal radioulnar rotation of the radial head on the ulna, two directions of motion that form part of Mills’ manipulation. This study also found that examiners were able to identify the symptomatic elbows with the use of motion palpation. It is recommended that future research continue from this study in assessing the identification and presence of manipulable subluxations in all the extremity joints. However the methodological problems with the statistical analysis need to be addressed.

Ankle injuries comprise more than 15% of all sports injuries worldwide. The efficacy of the ankle taping for injury prevention has long been under scrutiny as numerous studies have shown that tape rapidly loses its ability to constrain ankle motion with exercise. Consequently, ankle braces (orthoses) are being used with increasing frequency for the prevention and functional management of ankle injuries. However, the motion restraining qualities of ankle orthoses have not been widely evaluated in closed kinetic chain environments under physiologic loads. The primary purpose of this study was to compare the abilities of four ankle orthoses (ankle taping, lace-up brace, semirigid orthosis and hybrid brace) against a control condition (no brace or tape) to control subtalar and talocrural motion during running on a laterally-tilted treadmill at 16.2 km/h before and after exercise. It has been hypothesized that ankle orthoses make a secondary contribution to injury prevention through enhanced proprioception. The secondary purpose of this study was to quantify the effects of the aforementioned ankle orthoses on
postural stability during single-limb stance following a bout of exercise. Fifteen healthy university students (8 men and 7 women) with no history of significant ankle injuries (age, mean �� SD: 22.9 �� 3.9 years) volunteered to participate in this study. Three-dimensional kinematic data were captured with an active infrared digital camera system sampling at 120 Hz. To address the first question, data analyses were performed using 2way univariate (Ankle Orthoses x Pre/Post-Exercise x Subjects) (5 x 2 x 15) repeated measures analysis of variance (ANOVA) to determine the existence of differences among three closed and four open kinematic chain dependent measures before and after exercise. Maximum inversion angles (MAXINV) were similar for all ankle orthoses, with no orthosis limiting inversion during tilted treadmill running significantly more than another, or compared to the control condition, either before or after exercise (p>.05). Pre-exercise MAXINV group means and standard deviations during treadmill running ranged from 6.8 �� 3.4 deg with the Royce Medical Speed Brace to 9.5 �� 4.1 deg in the tape condition; post-exercise MAXINV mean values ranged from 7.6 �� 3.2 deg for the Aircast Sport Stirrup to 9.1 �� 4.6 deg with closed basketweave tape. While not statistically significant (p=0.10), ankle taping provided the least amount of inversion restraint, both before and after the exercise bout. The MAXINV angles measured during treadmill running (8.2 �� 4.0 deg) and open chain inversion AROM measured with a goniometer
(34.5 �� 6.2 deg) were not related (r=-0.0003). The compressive forces present during closed kinetic chain activity are known to increase joint stability and thus may explain why MAXINV under dynamic varus loads was so much less in magnitude than inversion AROM measured under open kinetic chain conditions. The nonlinear relationship of these two variables supports our contention that reports of the motion controlling properties of ankle orthoses measured in open kinetic chain environments should not be used to infer the response characteristics of these same orthoses under dynamic, physiologic loads. To address the second question, data were analyzed using 3-way univariate (Ankle Orthoses x Pre/Post-Exercise x Eyes Open/Closed x Subjects) (5 x 2 x 2 x 15) repeated measures ANOVAs. Subjects' postural stability was assessed using a Biodex Balance System with eyes open and eyes closed conditions, before and after an exercise bout. The ankle orthoses evaluated did not influence postural stability as measured by mediolateral sway index, anteroposterior sway index, and overall sway index. Removal of visual perception via blindfolding resulted in significant decreases in all three measures of postural stability (p=.001). There was poor association among the closed chain postural stability parameters and the open chain AROM measures. These correlations ranged from r=.04 to .17, indicating minimal relationship between the amount of AROM permitted by the orthoses and postural stability as quantified by this method.Graduation date: 2000

Submitted as the dissertation component in partial fulfilment of the requirements for the degree of a Masters in Technology in Chiropractic in the department of Chiropractic and Somatology, Durban University of Technology, Durban, South Africa, 2017.Background: Hip pain is a common problem. Motion palpation is a manual technique applied by the hands in various degrees of joint motion that specifically evaluates range of motion in relation to specific anatomical landmarks, joint play and end feel. Motion palpation remains one of the most used diagnostic techniques and yet it remains unclear whether or not it is a reliable, sensitive and specific tool; especially in the hip joint. Objectives: This study assessed intra- and inter-examiner reliability and clinical responsiveness of motion palpation when it is used as a diagnostic tool in patients with non-specific unilateral anterior hip pain and unilateral asymptomatic hip joints. Methods: Ten participants, between the ages of 18 and 60, were included in this study (three ballet dancers, three golfers and four participants from the general population). The participants were assessed randomly by three blinded examiners. All of the participants then received one adjustment delivered by the researcher (half on the symptomatic side and half on the asymptomatic). The participants were then re-assessed. Data was recorded on a data collection sheet and analysed using SPSS version 23. Intra-examiner reliability and clinical responsiveness were analysed using McNemar’s test and the Chi-Square Test of Independence. Inter-examiner reliability was analysed using Fleiss’ Kappa. Results: Intra-examiner reliability showed to be markedly better on the left-hand side for all three examiners. Kappa scores for inter-examiner reliability varied from none to perfect. The average pairwise agreement scores ranged from 33.3% to 100% at the first assessment, and from 46.6% to 100% in the second assessment. A mean and standard deviation were calculated for the pairwise agreements which represented the sensitivity and specificity respectively. Both showed improvement between the first and second assessments which is positive for inter-examiner reliability. Clinical responsiveness was shown to be absent for examiners A and B but was present for examiner C on the left. Conclusion: This study found that, contrary to the expectations of many clinicians, motion palpation has limited to poor levels of intra-examiner reliability, inter-examiner reliability and clinical responsiveness. This is however limited by the small sample size and methodological limitations in this study. Therefore, the role of palpation as a diagnostic tool used in the diagnosis hip dysfunction may be limited.

AbstractMedia influence how we define and engage with our world, shaping our interpretations, attitudes, behaviours. Feature films in which work-related injuries, deaths, and disasters are the storylines can convey occupational safety messages to large, diverse audiences. Films can entertain, act as “powerful” and “poignant” memorials to workers, heighten peoples’ awareness of events, and even deepen their understanding of the causes of workplace disasters. However, it is unclear how films actually represent the complexities of workplace injury and industrial disaster. We examined the film Only the Brave (di Bonaventura, Luckinbill (Producers), Kosinski (Director) in Only the Brave [Motion Picture] (Columbia Pictures, United States, 2017)), which recounts the story of the deaths of 19 wildland firefighters in America. In particular, we examine how the film portrays workplace disaster and the factors which led up to the event. We discuss some strengths and limitations of feature films as a form of visualizing workplace disaster.

Abstract In the summer of 1968, amid the white walls of an otherwise unremarkable sixth-floor office space in Manhattan, Valerie Solanas aims a gun at Andy Warhol and shoots him. This was at once an event of relation and of montage, one that inextricably intertwined the fates of two lives through the violent “editing” of the body of the most famous artist in the world, setting into motion an entirely new sequence of images and works. In subsequent years, Warhol’s cut-and-sutured body entered into a complex constellation of images and practices, first in portraits by Richard Avedon and Alice Neel, and later in Warhol’s rarely discussed “bonus photographs,” knitting drawings, and sewn photographs. This chapter traces the circulation of Warhol’s stricken body (and its attendant wounds) across this unlikely constellation of works, before turning to a close engagement with what was arguably the artist’s longest-running project, the “stitched photographs,” made up of multiple identical photographs stitched together with thread. This chapter argues that the true content of these objects lies not in the pictures themselves but in the visible threads holding them together. Against a conception of the cut as a threatening or even traumatic space, Chapter 1 places Warhol’s unorthodox objects (and his photographic practice in general) in conversation with the film-theoretical discourse of suture.
