The aim of this study was to investigate the effect of cumulative mild head injury on the cognitive functioning of professional rugby players. A comprehensive battery of neuropsychological tests was administered to 26 professional rugby players and to a comparison group of 21 professional cricket players. The group test results of the rugby, cricket, rugby forwards and rugby backline players were each compared with established normative data. Generally, the comparison of the rugby and cricket mean scores relative to the normative data did not reveal significant differences on tests known to be sensitive to the effects of mild head injury. However, the comparison of variability for each of the rugby and cricket playing groups relative to variability for the normative data, revealed a pattern of increased variability among the rugby players. This implies a bimodal distribution in which a significant number of rugby players were performing poorly across these tests whereas a significant proportion were not. This variability effect was accounted for by further mean score comparisons which revealed that, as a group, it was the forward players whose performances were disproportionately poor on tests sensitive to the effects of mild head injury. The implications of these results are developed theoretically within the context of brain reserve capacity theory and suggestions for future research are provided.

Magister Scientiae (Physiotherapy) - MSc(Physio) / Being involved in soccer in Rwanda at both national and international level exposes soccer players to the risk of injury. The aim of this study was to identify common soccer injuries among the 1st and 2nd division soccer teams in Rwanda and to establish the need for physiotherapy intervention. This deals with the first two stages of injury prevention, which included identification and description of the extent of the problem and the identification of factors and mechanisms that play a part in the occurrence of injuries. / South Africa

The study sought to determine whether there is evidence for the presence of residual (chronic) deleterious effects on cognition due to repetitive mild traumatic brain injury in top team university level rugby players, using ImPACT 3.0, Trail Making Test (TMT) and Digit Span. The initial sample of 48 participants was divided into groups; Rugby (n = 30) and Controls (n = 18), Rugby Forwards (n = 14) and Rugby Backs (n = 16). A reduced sample (N = 31) comprised of Rugby (n = 20) and Controls (n = 11), Rugby Forwards (n = 9) and Rugby Backs (n = 11). Comparative subgroups were equivalent for estimated IQ but not for age and educational level in the full sample; in the reduced sample there was equivalence for all three variables of age, education and estimated IQ. All cognitive test measures were subjected to independent t-test analyses between groups at the pre- and post-season, and dependent t-test analyses for Rugby and Controls at pre- versus post-season. Overall, the results implicated the presence of deleterious effects of concussive events on Rugby players in the areas of speed of information processing, working memory and impulse control. Significant practice effects were found on the TMT and Digit Span for controls, but not on ImPACT 3.0, supporting the use of this computer-based programme in the sports management context.

The present study comprises the second phase of a larger and ongoing research study investigating the brain damage effects of cumulative mild head injury in rugby. The purpose of this study was to determine whether cumulative mild head injury sustained in the game of rugby would cause brain injury as evidenced by impaired performance on sensitive neuropsychological tests. Participants were Springbok professional rugby players (n = 26), Under 21 rugby players (n = 19), and a non-contact sport control of national hockey players (n = 21). Comparisons of performance were carried out across a spectrum of neuropsychological tests for the three rugby groups (Total Rugby, Springbok Rugby, and Under 21 Rugby) versus the performance of the non-contact sport control group (Hockey Control), as well as comparisons of performance f9r the subgroups of Rugby Forwards versus Rugby Backs. Comparisons revealed a consistent pattern of poorer performance across all rugby groups relative to the performance of the controls on tests highly sensitive to the effects of diffuse brain damage. Within rugby group comparisons (Forwards versus Backs) showed significantly poorer performance for Total Rugby Forwards and Springbok Rugby Forwards relative to the performance of the respective Total Rugby Backs and Springbok Rugby Backs on sensitive, as well as on somewhat less sensitive, neuropsychological tests. The performance of Under 21 Rugby Forwards relative to Under 21 Rugby Backs demonstrated similar trends. Brain reserve capacity theory was used as a conceptual basis for discussing the implications of these findings.

A number of computerised tests have been especially developed to facilitate the medical management of the sports-related concussion. Probably the most widely used of these programmes is the ImPACT test that was developed in the USA and that is registered with the HPCSA for use in the South African context. A recent Afrikaans version of the test served as the basis of the present study with the following objectives: (i) to collect Afrikaans ImPACT normative data on a cohort of Afrikaans first language adolescent rugby players with Model C education for comparison with existing South African English first language adolescent rugby players with Private/Model C schooling, and (ii) to investigate the pre-versus postseason ImPACT neurocognitive test profiles of this cohort of Afrikaans first language adolescent rugby players versus equivalent noncontact sports controls. The results for Part 1 of the study generally demonstrate poorer performance in respect of the Afrikaans cohort, which is understood to be the result of poorer quality of education. The results for Part 2 demonstrated failure of the rugby group to benefit from practice on the ImPACT Visual Motor Speed composite score to the same extent as the control group. It is argued that this apparent cognitive vulnerability in the rugby group is due to lowered cognitive reserve capacity in association with long term exposure to concussive and sub-concussive injury.

This study investigated the cumulative effect of mild head injuries on rugby players. A comprehensive battery of neuropsychological tests was administered and subjects completed a self-report postconcussive symptom questionnaire. Data were collected for the two rugby groups, Springbok rugby players (n = 26) and Under 21 rugby players (n = 19), and for the control group, national hockey players (n = 21). Group comparisons of the percentage of individuals with deficit or self-reported symptomatology were made between: (i) the contact sport groups and the control group; (ii) the forwards and the backs within each rugby group and the rugby forwards and the control group; and (iii) the Springbok and Under 21 rugby players. Broadly speaking, comparative results on the neuropsychological tests and the self-reported postconcussive symptoms clearly distinguished between contact sport players and non-contact sport players and indicated the presence of diffuse brain damage in the contact sport players. There was also clear evidence of positional variation within the rugby groups, with the forwards (more full contact positions) most susceptible to impairment. Neuropsychological test results revealed deficit in information processing speed, attention and concentration, mental flexibility, visual memory and verbal new learning. The most significant neuropsychiatric complaints were reported in the areas of memory, social contact, sensitivity to noise, lowered frustration tolerance, anxiety and worry, and depression. The most sensitive neuropsychological test used in the present study was the Digit Symbol Substitution test. This test clearly distinguished contact sport players from non-contact sport players, and forwards from backs.

The present study comprises part of an ongoing research study investigating the effects 0 f cumulative mild head injuries 0 n Rugby Union p layers. The aim 0 f t he study was to ascertain whether there are neuropsychological effects of cumulative mild head injuries sustained during the rugby-playing careers of senior schoolboy rugby players. Participants were top-level rugby players from high schools in Grahamstown and Cape Town (n = 79) and non-contact sport controls of top-level field hockey players from the same schools (n = 58). Group mean comparisons across a battery of neuropsychological tests were carried out between the Total Rugby versus the Total Field Hockey group, and the Rugby Forwards versus the Rugby Backs group. Comparisons between Total Rugby versus Total Field Hockey revealed impaired performance by the rugby players on two tests of visuoperceptual tracking, namely Digit Symbol Substitution and Trail Making Test (Part A). For Rugby Forwards versus Rugby Backs, there were no consistent differences to support the expectation that forwards would perform worse than backs. Forwards performed more poorly than backs on WMS Associate Learning Subtest - Hard (Delayed Recall), whereas backs performed more poorly than forwards on Digits Backwards. This suggests that some individuals in the cohort were starting to exhibit verbal memory deficit, albeit not clearly in association with forward positional play. Overall, results of the present study provide tentative support for the hypothesis that school level rugby players are more susceptible to the effects of cumulative concussive and sub-concussive head injuries than are non-contact sport controls. / KMBT_363 / Adobe Acrobat 9.54 Paper Capture Plug-in

The interest in football injuries has increased with the increased enthusiasm for the sport. The coach is finding it more and more important to have all of his players in the best possible condition to withstand the terrific strain under which they must compete. The public wants to see a well played, exciting game, but the days of brutality seem to be vanishing. The average fan would rather see the best players play in the game than to have them sit on the bench in plaster casts. This has led to a series of quite wide-spread investigations dealing with the problem during the past few seasons. The results, while not final, seem to show that a large percentage of the injuries are preventable. If this is true, further research will certainly be worthwhile. The inspiration for this present investigation came as a result of thirteen years' experience as trainer for athletic teams. During this period most of the games were played by a small squad, frequently further reduced by injuries. It is natural, then, to endeavor to discover hew to strengthen the squads by a study of the causes and treatment of these injuries.

submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, Durban, South Africa, 2015. / Background Rugby union is one of South Africa’s most popular sports; it requires high levels of skill and fitness and is played at a high intensity and speed which allows for a greater risk of injury. The high risk of injury is said to be due to the nature of the physicality of rugby. It is because of this high risk of injury that several adaptations of rugby have since developed which rely more on speed and agility than physicality. These adaptations include tens or ten-a-side rugby, sevens or seven-a-side rugby and finally touch rugby, which is played with six players a-side. Each adaptation has its own set of rules and is played differently to the traditional rugby union or fifteen-a-side rugby. Hence, in these adaptations the physicality is said to decrease with a resultant increase in demand for speed and agility. The reduction of physicality and increase in the need for speed and agility would imply that the nature of injuries sustained will be different to those sustained in traditional rugby union. Objectives To develop a profile of injuries that describe the type, anatomical location and mechanism of injuries sustained in tens, sevens and touch rugby; to compare the injuries sustained between the three groups; and, to analyse management strategies utilised by chiropractic students at the 2014 Durban ‘Rugby Rush Tournament’. Additionally this study aimed to provide recommendations to the injury reporting form utilised. Method This study was a retrospective, quantitative, descriptive study based on the Chiropractic Student Sports Association’s report form in order to produce a retrospective cohort analysis of injury and treatment profiles. Participants who made use of the chiropractic treatment facility were required to complete the informed consent section of the injury reporting form. The chiropractic intern was required to complete the remainder of the form pertaining to the participant, complaint and treatment information. This study was limited to event participants to allow for subgroup analysis. The forms were then captured and analysed. Results The data collected consisted of a total of 345 individual patient forms which indicated 626 visits for a total of 733 complaints. The average participant age was 24 ± 5.58. The study found muscle strains (41.5%), SI Syndrome (17.6%) and Joint sprains (15.0%) to be the most frequent diagnoses. A history or previous injury or trauma was reported in 18.7% and 7.40% respectively. Acute injuries accounted for 64.3% and 35.7% were recorded as chronic in nature. The most frequent mechanism of injury was that of overuse (81.9%) and trauma accounted for 17.2% of injuries. The lumbar region (26.1%), thigh (20.7%) and shin/calf (15.6%) were the most commonly reported regions of complaint. Manipulation (58.8%), massage (32.0%) and stretch PNF (27.9%) were the most frequently used treatment protocols. Strapping was utilised in 21.1% of injuries of which 5.20% was applied to the muscle and 13.6% was applied to the joint. No comparison was made using the sevens subgroup as there were insufficient records, thus only tens and touch players were compared. A borderline non-significant difference (p = 0.057) was noted between the type of player and the history of previous trauma. Tens players were more likely to have a history of trauma compared to touch players. A significant difference (p = 0.001) was found between the type of athlete and mechanism of injury. Overuse was more common in touch players whereas trauma was more common in tens players. Due to statistical inconsistencies no significance tests were applicable to compare the type of player and region of complaint. Recommendations were proposed in order to avoid this in future research. Conclusion This study provides a base of knowledge regarding the injuries that were presented to the chiropractic treatment facility at the 2014 Durban ‘Rugby Rush Tournament’ and the management strategies utilised by the chiropractic interns at the event. This research provides insight into injury profiling of tens, sevens and touch rugby players. There were several recommendations proposed for future researchers in order to expand on this field of knowledge.
