Abstract
Background: Prolonged participation in overhead sports
creates shoulder muscle imbalances which eventually alter the
efficacy of the shoulder stabiliser muscles and heighten injury
risk, such as subacromial impingement syndrome.
Objectives: The aim of this study was to determine if
ultrasound is effective to measure the acromiohumeral
distance (AHD) to compare the effect of the scapular
assistance test (SAT) on the AHD with a prehabilitative
exercise intervention programme in asymptomatic cricket
players.
Methods: Baseline testing on cricket players from the North-
West University cricket squad (N=34) included AHD
measurements performed by a sonographer at 0°, 30° and 60°
humeral abduction angles respectively, with and without the
SAT application. Players were then randomly assigned to an
intervention and control group...
