Brief summary

The purpose of this study is to determine whether there are any significant differences between amateur cricket pace bowlers and a healthy control population in side to side differences of lumbar multifidus resting thickness and recruitment between sides.

Interventions

Cross-sectional observational study using real-time ultrasound to measure lumbar multifidus resting thickness and recruitment in amateur pace bowling cricketers and non-cricketers (the "control"group). Single session measurements to be performed with no follow up required. Approximately 15-20 minutes per session required to perform all measurements. A fourth year undergraduate Bachelor of Physiotherapy (Honours) student is assigned as the principal investigator and performed all measurements.
