Rotator cuff tear (RCT) is a highly prevalent age-associated musculoskeletal injury that can diminish upper limb function and independence. Current RCT assessments only focus on movement and biomechanical factors (e.g. strength) at the shoulder. Nevertheless, whole-arm movement may be altered. The goal of this project is to identify changes in arm movements of daily activities are affected by RCT. The obtained knowledge will provide needed evidence to develop targeted therapeutic approaches to improve upper limb function for this group. Occurrence of RCT increases with age, and therefore, the project focusses on people older than 55. Two groups are included, those who do not have a RCT and those who have been diagnosed with a RCT but not yet treated.
