Why is this relevant?:
Previous studies show rounded-shoulder posture to be associated with scapular dysfunction (1-3). Individuals exhibiting this dysfunction commonly have adaptive shortening of the pectoralis minor, contributing to changes in resting and dynamic scapular position (4). Left unaddressed, postural dysfunction predisposes individuals to numerous shoulder pathologies from subacromial impingement, to degenerative rotator cuff pathology, to loss of force production of the musculature surrounding the glenohumeral joint (3). The current study sought to determine whether or not manual therapy and stretching of pectoralis minor reduces rounded-shoulder posture and increases lower trapezius strength in healthy 20- to 40-year old individuals.
