EFFECTS OF MUSCLE FATIGUE ON SHOULDER JOINT POSITION SENSE
INTRODUCTION The shoulder complex relies heavily on sensory motor control for maintaining functional joint stability, due to its poor osseous and capsuloligamentous stability. Proprioceptive deficits have been related to shoulder injuries and some studies have shown that muscle fatigue can also decrease propriocetive acuity [1 3] However, these studies have focused on shoulder internal and external rotation movements, which may not be functional for the general population. Therefore, this study aimed to investigate the effects of muscle fatigue on shoulder joint position sense during an active repositioning task at different angles of shoulder elevation in the scapular plane.
