Following a power calculation with the statistician (Peter Knight) it is thought that this study will need a minimum of 40 patients to make it clinically significant. Sample numbers of 40-50 have been recommended in the literature (Hicks 1999). However it is accepted that the larger the sample the greater the probability of randomness and chance operating as expected and this will reduce the chance of a sampling error (Hicks 1999).
Sample: Sample is one of convenience: patients over 18 with shoulder pain attending an outpatient clinic at the Royal Orthopaedic Hospital who have been referred for ultrasound.
