Effects of Wearing Shoulder Taping Garments on Upper Extremity and Spinal Alignment, Range of Motion, Muscle Strength, and Activation

Abstract

Purpose: This study aimed to scientifically investigate the effects of functional shoulder taping garments on upper extremity function, postural alignment, and muscle activation.

Methods: Twenty healthy adults participated in the experiment, performing standardized assessments under two conditions: wearing taping garments and wearing conventional garments. Range of motion (ROM), spinal alignment, scapular distance, shoulder muscle strength, and the electromyographic (EMG) activity of four major muscles (pectoralis major, biceps brachii, triceps brachii, and rhomboid major) were evaluated. Motion analysis and surface electromyography systems were employed to acquire quantitative data, and a hand-held dynamometer was used to assess muscle strength.

Results: Wearing taping garments significantly increased shoulder flexion ROM (p<0.05). Spinal alignment improved, as indicated by an increased thoracic angle and a decreased scapular distance (p<0.05). EMG activity of the pectoralis major, biceps brachii, and rhomboid major significantly increased under maximal contraction when compared with conventional garments (p<0.05). However, no significant differences were found in shoulder flexion or abduction strength.

Conclusion: These findings suggest that taping garments may enhance shoulder joint stability, facilitate muscle activation, and positively contribute to functional shoulder performance.
