Background: Pectoralis minor tightness is associated with reduced glenohumeral internal rotation range of motion (ROM) and scapular anterior tilt alignment. However, the synergistic effects of the pectoralis minor stretching exercise and scapular posterior tilt strategy on glenohumeral internal rotation ROM and pectoralis minor length remain unexplored.
Objectives: This study examined the effects of doorway stretching with scapular posterior tilt on pectoralis minor length, scapular alignment, and glenohumeral internal rotation ROM.
Design: A case series study.
Methods: Fifteen adults with pectoralis minor tightness performed doorway stretching with scapular posterior tilt. Pectoralis minor length, acromion–table distance, and glenohumeral internal rotation ROM were measured before and immediately after stretching. The pectoralis minor length was calculated using the pectoralis minor index. The measured variables were analyzed using a paired t-test.
Results: While the pectoralis minor index and glenohumeral internal rotation ROM significantly increased, the acromion–table distance markedly decreased after doorway stretching with scapular posterior tilt (P<.05).
Conclusion: Based on the present findings, doorway stretching with scapular posterior tilt could be an effective exercise for increasing glenohumeral internal rotation ROM and pectoralis minor length.
