Injuries include internal and external snapping hip, non-specific hip and low back pain, IT band problems, labral tears, hip impingement, and spondylolisthesis. Depending on the site and severity of the injuries, common treatments range from surgical to conservative (e.g. - manual therapy, exercise, Functional Electronic Stimulation, iontophoresis). It is reported that most dancer injuries result from overuse and are related to poor technique. All three PTs interviewed also note that injuries are often a result of choreographic demands on the dancer and recommend breathing techniques and neuromuscular re-patterning for rehabilitation. / Committee in Charge: Steven J.

M.Tech. / Dancing, over the years has become a highly competitive sport with demanding levels of fitness and flexibility needed in order to progress to a professional level (DeMann, 1997). With lower back pain becoming a common occurrence in dancers, both physical as well as emotional stress is placed on the dancer and their lower back (DeMann, 1997). The aim of this study was to compare the effectiveness of Chiropractic adjustments on the lumbar spine and Sacroiliac joints, stretching certain muscle groups or the combination of the two treatment protocols on Freestyle dancers with chronic lower back pain with regards to pain, disability and lumbar spine and pelvis range of motion. Thirty female participants between the ages of thirteen and twenty five years were recruited to participate in this study. Successful participants were then randomly placed into one of three groups, of ten participants each, which would receive different treatment protocols according to their group allocation. Group 1 underwent Chiropractic adjustments to the lumbar spine and Sacroiliac joints, Group 2 received stretching exercises to the Quadratus lumborum muscle; gluteal muscles consisting of Gluteus maximus, medius and minimus; Piriformis; Psoas; Hamstring and Multifidus muscles only and Group 3 received a combination of the treatment protocols. Participants in all three groups were assessed using the Numerical Pain Rating Scale and the Roland-Morris Disability Questionnaire for subjective readings; the Digital Inclinometer was used for objective readings of ROM. All treatments were performed at the Riviere Academy of Dance under the supervision of a qualified Chiropractor. The results concluded that the benefits of an adjustment alone, stretching alone as well as the two treatments combined showed a reduction of pain and increase of ROM, when managing a dancer with lower back pain. Not one treatment was shown to be more beneficial than the other.

Submitted in partial compliance with the requirements for the Master’s Degree in Technology: Chiropractic, Durban University of Technology, 2014. / Background: Classical ballet is an art form that seems graceful on the surface. However, beneath the disguise of beauty and ease lies an extremely physically demanding activity that calls for dedication, strength and perseverance. Ballet requires a specific body type and precise techniques, which predispose the dancer to musculoskeletal injury. Although a few studies have been conducted to investigate biomechanical factors as risk factors for injury in ballet dancers, few have included amateur ballet dancers and a range of biomechanical factors. Objectives: This study aimed to determine characteristics of ballet-related injury in amateur ballet dancers in the greater Durban area; to measure and record lower limb biomechanical measurements of these dancers; and to identify associations between the biomechanical measurements and characteristics of injury in the population. Method: A quantitative, questionnaire-based survey with biomechanical measurements was conducted on 21 amateur ballet dancers in the greater Durban area. Statistical analysis included the description of categorical variables using frequency and percentages in tables and bar charts. Continuous variables were summarised using mean, standard deviation and range, or median and range as appropriate. Independent Sample T-tests were used to compare biomechanical measurements between two independent groups. A p value <0.05 was considered as statistically significant. Pearson’s correlations and ANOVA testing were also used. Results: The period prevalence of ballet-related injury over the last 2 years was found to be 62% and the point prevalence 38%. There were 37 total previous injuries, most of which occurred in the hamstring (24%). Most of the worst previous injuries were reported to have occurred in the low back (31%). Most of the worst previous (70%) and current (93%) injuries occurred over time. The worst previous injuries reported ranged from mild to severe in severity, while the worst current injuries reported ranged from mild to moderate. Significant associations were found between right weight-bearing ankle dorsiflexion and previous injury; right weight-bearing ankle dorsiflexion and current injury; ‘functional turnout’ and onset of injury; right non weight-bearing ankle dorsiflexion and onset of injury; and ‘compensated turnout’ and onset of injury. Conclusion: The results suggest a significant association between musculoskeletal ballet-related injury and reduced weight-bearing ankle dorsiflexion; between injuries that occur over time (overuse injuries) and decreased ‘functional turnout’; and between overuse injuries and decreased non weight-bearing ankle dorsiflexion. These findings may help identify risk factors for injury in ballet dancers and contribute towards preventing ballet-related injury. / M
