Factors associated with chronic plantar heel pain: A matched case–control study
Abstracts trunk side bridge being significantly lower in those with poor single leg squat performance. doi:10.1016/j.jsams.2006.12.011 10 Scope of sports chiropractic required for the successful prevention of hamstring and other lower limb injury H. Pollard, W. Hoskins Macquarie Injury Management Group, Macquarie University, Australia Aim: To document the scope of sports chiropractic required for the successful prevention of hamstring and other lower limb injuries occurring in semielite Australian Rules footballers by identifying the type, location and reason for treatment provided in a season-long RCT. Methods: Treatment for the intervention group for the entirety of the study was continuously recorded and determined as being for symptomatic benefit for a self-reported complaint or asymptomatic functional/performance improvement. Treatment was classified as being joint based (manipulation/mobilisation) or soft tissue based (massage/stretching) and categorised into the regions of the body. Results: Four hundred and eighty-seven treatments were provided to 29 intervention players, 65.3% were delivered to asymptomatic regions and 34.7% symptomatic regions. Of the joint based therapy 73.5% was asymptomatic and 26.5% symptomatic. The most common asymptomatic joints treated were the thoracic spine (21.3%), knee (20.5%) and hip (19.0%) and symptomatic joints were the lumbar spine (24.3%), thoracic spine (16.7%) and hip (14.0%). Of the soft tissue based therapy 58.0% was asymptomatic and 42.0% symptomatic. The most common asymptomatic soft tissue regions treated were the gluteal region (22.0%), hip flexors (13.8%) and knee (13.0%) and symptomatic regions were the gluteal region (21.5%), lumbar region (14.2%) and thoracic region (7.6%). For joint based therapies 53.8% of treatment was directed at the spine with 46.2% directed at peripheral regions. Conclusion: Successful injury prevention in this cohort required an individualised full body sports chiropractic approach addressing soft and joint tissues in spinal and peripheral regions. doi:10.1016/j.jsams.2006.12.012
7 11 Factors associated with chronic plantar heel pain: A matched case—control study D. Irving, J. Cook, H. Menz Musculoskeletal Research Centre, La Trobe University, Melbourne, Australia Chronic plantar heel pain (CPHP) is one of the most common soft tissue disorders of the foot, yet its aetiology is poorly understood. The purpose of this matched case—control study was to examine the association between CPHP and a number of commonly hypothesized causative factors. Eighty subjects with CPHP were matched by age and sex (±2 years) to eighty control subjects. The two groups were then compared on measures of body mass index (BMI), foot posture index, calf strength, ankle dorsiflexion range of motion and occupational activity. The CPHP group was found to have significantly greater BMI, a more pronated foot posture, greater ankle dorsiflexion range of motion and during an average working day performed more squatting and carried heavier weights. No difference was identified between the groups for calf strength or mean occupational time spent sitting, standing, walking on uneven ground, climbing or lifting. Logistic regression revealed that obese individuals (BMI > 30 kg/m2 ) were 2.9 times more likely to have CPHP and those with pronated foot posture 3.7 times more likely. The findings of this study support previous evidence of an association between CPHP and both increased BMI and pronated foot posture. The association with increased ankle dorsiflexion is in contrast to previous evidence and questions the rationale for treatments aimed at increasing calf flexibility. doi:10.1016/j.jsams.2006.12.013 12 Results of surgery for Achilles tendon overuse injuries S. Orava, J. Hein¨ anen Mehilainen Hospital and Sports Clinic, Finland We wanted to see if the results of operative treatment of chronic Achilles tendon overuse injuries between two materials were different. The first series was from years 1986 to 1991 and the second from 2000 to 2004. There were 275 patients in the first series and 322 in the second series. The operations were done by the same orthopaedic surgeon and the same classification of diagnoses obtained from surgery were used. The mean age of
