Item A study of the effectiveness of myofascial trigger point therapy on iliotibial band friction syndrome in sports persons(1997) Hall, Thandi Antonia; Jones, Andrew D.Iliotibial Band Friction Syndrome is a common problem for patients as well as physicians. Many treatments have been devised for Iliotibial Band Friction Syndrome, but there is very little research to substantiate which of these treatments is most effective. Myofascial trigger points are a frequently overlooked and misunderstood phenomenon in the medical curriculae, yet with correct diagnosis and appropriate treatment the prognosis of these trogger points is usually excellent. The aim of this placebo-controlled study was to justify the hypotheses which stated that myofascial trigger point therapy would be effective in the treatment of Iliotibial Band Friction Syndrome (IBFS), as compared to detuned ultrasound as a form of treatment.Item The effectiveness of needling of myofascial trigger points on internal- external muscle peak torque and total work ratios of the shoulder rotator myoatatic unit in overhead throwing athletes suffering from myofascial pain and dysfunction syndrome(2005) Royce, Nicholas; Kruger, Brian; Korporaal, Charmaine MariaThe purpose of this study was to determine whether dry needling of myofascial trigger points (TrP's), found in the shoulder rotator myotatic unit, had an effect on the peak torque and total work parameters of the shoulder myotatic unit and by inference, the relative external rotation strength deficit in over-head throwing athletes. Athletes who perform overhead throwing sports such as: baseball, javelin, swimming/waterpolo and tennis, are susceptible to sustaining a micro-traumatic injury of the rotator myotatic unit of the shoulder, owing to repetitive high velocity mechanical stress placed on the shoulder at the extreme ranges of motion. The inherent structure of the shoulder, with three external rotators and five internal rotators, causes a muscle imbalance before an activity, such as throwing occurs, and this can predispose an athlete to Repetitive Stress Injuries (RSI) as a result of overuse or overload. The incidence and activation of TrP's in shoulder muscles can be accounted for on the basis of mechanical stress such as overuse / overload and thus could change muscle fiber co-ordination (muscle activity) and precipitate a painful lesion. It can be seen in current literature that TrP's produce a number of signs and symptoms such as: spasm of other muscles, weakness of involved muscle function, loss of co-ordination and decreased work tolerance of the involved muscle . Therefore the TrP's present in the shoulder rotator unit could contribute to changes in internal/external rotation ratios in over head athletes, and thus by deactivating or eliminating these TrP's, it is possible that these ratios may beItem A profile of injuries and contributing factors in premier league cricket players in the greater Durban area(2009) Tychsen, Rory Arthur Ludwig; Haswell, GarrickObjective: Literature has focused its efforts on professional cricket players and player related risk factors to injury with little information being available with regards to coaching / management and environmental risk factors to injury. Therefore, this study aimed to profile the injuries and risk factors in Premier League club cricketers in the greater Durban area. Methods: This was a prospective, cross-sectional based study, using a self-administered questionnaire, developed specifically for this research utilizing a focus group and pilot study. The questionnaire consisted of a demographics section, as well as an injury history and risk factor section. Letters of informed consent and questionnaire were distributed to 144 players / coaches for completion. Data was analysed using Pearson‟s correlation and t-tests. Results: A response rate of 70% (n=109) was achieved. Selected parameters from demographics, injury history and risk factors were found to be significantly related to current and / or previous injury. Conclusion: It is advised that coaches heed significant injury parameters in order to improve player health, decrease injury risk and decrease time out of play. Key words: Athletic injuries; questionnaires; cross-sectional study‟s; risk factors; sports; sports medicine; risk assessment; cricket.Item A study to determine the international federations' perception and utilization of chiropractors and other sports medical personnel(2008) Cloete, Kirsten Leigh; Korporaal, Charmaine MariaObjectives: To investigate the International Sports Federations’ (IFS) perception and utilization of chiropractors and other sports medical personnel, and to compare results between the executive committees and medical commissions within federations. Methods: A specially designed, quantitative questionnaire was used to collect data from the 65 federations belonging to the General Assembly of International Federations of Sport (GAIFS). The questionnaire distribution took place via e-mail, with the secretary of each federation being requested to forward a copy of the questionnaire to a member of the federation’s executive committee and medical commission respectively. Follow-up telephone calls were also made to further encourage a response from participants. After an 8-week period, returned questionnaires were collected and data was analyzed. Results: From the results obtained (30% response rate), it would seem that perceptions vary greatly. This is most evident when one compares the perceptions of the medical commission members to those of the executive committee members. The medical commission on a whole, appears to favour the more traditional medical professions, while the executive committee seems to be more holistic in their approach to treatment options. In terms of current utilization, chiropractors are currently represented on 16% of medical teams, although chiropractors are able, within their scope of practice, to provide 70% of the federations’ most requested techniques / modalities for competitions. There appears to be little / no criteria governing the selection of medical personnel, however most of the federations agreed that a chiropractor with a post-graduate diploma in sports injuries, would be seen in a more favourable light for selection. Conclusions: The perceptions and utilization of chiropractors and other sports medical personnel varies greatly between federations, which may be due to a number of factors related to the formulation of perception itself. In addition, there appears to be a discrepancy between the opinions of the executive committees and medical commission of the participating federations.Item Gymnastics injuries: a quantitative profile of athletes in the greater Durban area(2006) Adamson, Ingrid; Lakhani, EktaThe aim or purpose of this study is to determine the injury profile of gymnasts in the greater Durban area of KwaZulu-Natal, South Africa; and to compare it with the international data that are available. Factors that should be considered regarding differences in the injury profile of South African gymnasts as compared with international gymnasts include: 1. Difference in standard of gymnastics (Cameron-Smith, 2005) 2. Sudden increase in the standard of South African gymnastics in an attempt to match that of other countries, which may lead to an increase in training hours, and attempts at more risky new manoeuvres. This, in turn, may increase the risk of injury (Cameron-Smith, 2005). For the purpose of this study, the following information was gathered in terms of: - Demographics of South African gymnasts - The participants’ gymnastics history - The presence of any past or current injuries, and - If present, factors relating to these injuries were investigated. This information mentioned above was gathered with the aim of helping to identify any problems that may exist, quantifying the extent of these problems and identifying to some extent the potential risk factors. This would be beneficial to South African gymnasts if recommendations for prevention of potential injuries were made, should any common injuries, or possible risk factors or associations be discovered/identified (Chadwick, 2004).Item An investigation into the knowledge and perception of rugby coaches in the greater Durban area with regards to chiropractic and other sports medical personnel(2008) Butt, Charlton Kenneth; Korporaal, Charmaine MariaIntroduction: One of the most important responsibilities of a rugby coach towards players is that of injury prevention and advice. Often these responsibilities fall solely on the coach, but sometimes he has the benefit of sports medical personnel at his service. Therefore in order for the coach to best service this sport and industry, his/her knowledge and perception of Chiropractic and other sports medical personnel is critical. Objective: To establish an understanding of Durban rugby coaches’ perceptions and knowledge of Chiropractic to formulate initiatives aimed at bridging gaps and building co-operation between coaches and various medical personnel that they have at their disposal. Methods: A survey was distributed to 149 rugby coaches within 23 high schools and 67 rugby coaches within 24 rugby clubs, resulting in a total of 219 rugby coaches in the greater Durban area received a questionnaire for completion and return. Results: Of the 85 coaches that participated (38.8% response rate), the majority were White (95%), male (99%), with a mean age of 37.36 years and coached at the amateur level (65.1%). School coaches dominated the participants with 67.1% with 61 (71.8%) having obtained a rugby coaching qualification and 26 (30.6%) having another professional sport, fitness or medical qualification besides that of rugby coaching. Most (94.9%) participants referred players to a health professional for examination and / or treatment. This included Physiotherapists, 80% of the time, GPs 70.6% of the time and Chiropractors, 60% of the time. Twenty-nine (34.1%) had a Chiropractor on their medical management team and 28 (96.6%) said it was a positive experience. Of those who did not have a Chiropractor on the team, 82.4% said they would consider it in the future. Over half (65.5%) had personally been treated by a Chiropractor. The 3 most frequent conditions associated with Chiropractic included: Disc herniation (42.6%), low back pain (36.1%) and whiplash (32.8%). Notwithstanding this outcome, the level of knowledge was low with the mean knowledge score (an aggregate knowledge score derived statistically from all questions relating to the knowledge of Chiropractic) of the group was 55.8% (SD 21.9%), even though the range varied from 0 to 96%. Although the coaches’ knowledge of Chiropractic was low, most participants (76.2%) had a favourable view of the Chiropractic profession. Furthermore the coaches perception of Chiropractic related significantly to their knowledge (p = 0.037). In addition the higher their knowledge scores the more positive their view. Conclusion: This study established what knowledge base is available that could promote rugby coaches greater understanding of the Chiropractic profession and related medical personnel. There was a positive association between increased knowledge and a better perception of Chiropractic, suggesting that if knowledge were improved, then perception and attitude towards Chiropractic and related medical personnel would further improve. This increased awareness may improve knowledge, understanding, communication and utilization with the Chiropractic profession and related medical personnel and ultimately these professions within rugby may gain a greater level of acceptance.Item The association between active myofascial trigger points of the shoulder external rotator myotactic unit on altering internal/external peak torque and single repetition work ratios in overhead throwing athletes(2005) Audie, Gregg; Kruger, BrianThe purpose of this study was to investigate the association between active Myofascial Trigger Points in the dominant shoulder external rotator muscle group in overhead throwing athletes and an altered internal/external rotation peak torque and single repetition work ratio of the involved shoulder.Item The effectiveness of gluteus medius and iliotibial band stretching, versus strengthening, in the rehabilitation of iliotibial band syndrome in long distance runners(2005) Gangat, A.
