- Primary Outcome Measures
Name Time Method Statistical difference between cricket pace bowlers and non-cricketers when comparing left and right sides of lumbar multifidus resting thickness. Ultrasound imaging (Venue 40 Model R1.x.x; GE Helathcare, Jiangsu, P.R. China) with a force probe (Gilbertson, M. & Anthony, B., 2011) for between image standardisation used to capture images of the muscle. Image J software will be used to analyse the images.[Baseline.]
