Abstract

Objective: To assess if joint position sense (JPS) in the shoulder differed between un-injured rugby players, matched control subjects and previously injured rehabilitated rugby players. Design: Mixed design. Setting: University biomechanics laboratory. Participants: 15 asymptomatic professional rugby union players, 15 previously injured professional rugby union players, 15 asymptomatic matched non-rugby playing controls had their JPS assessed. Main outcome measures: JPS was assessed using two criterion angles in the 90° shoulder abduction position (45° and 80° external rotation). Results: The study found a significant difference between groups in error score (p ¼ 0.02). The testing angle also had a significant effect on error score (p ¼ 0.002), with greater error scores occurring in the mid range position. Conclusion: This study showed rugby players to have better JPS than controls, indicating JPS might not be related to injury risk. Poor JPS appears to be related to injury, players having sustained an injury have decreased JPS despite surgery and/or rehabilitation and returning to sport without incident.
