Effect of Exercise of Shoulder - Pelvic Coupling Pattern on Breathing Using Proprioceptive Technique

The PNF combination of scapular and pelvic pattern intervention was conducted for 30 minutes per session, three times per week, for four weeks. The PNF combination of scapular and pelvic pattern was applied by combining scapular posterior depression with pelvic anterior elevation, and scapular anterior elevation with pelvic posterior depression. During scapular anterior elevation combined with pelvic posterior depression, the therapist placed their hands on the shoulder joint and acromion, and on the ischial tuberosity to provide resistance. During scapular posterior depression combined with pelvic anterior elevation, resistance was applied by placing the hands on the inferior angle of the scapula and the anterior superior iliac spine. Among the PNF techniques, rhythmic initiation was first used to facilitate movement education and enhance kinesthetic awareness. Afterward, dynamic reversals were applied to promote muscle strengthening in the participants.

The chest expansion exercise was performed in a seated upright position. The participant interlocked their fingers behind the head and, during exhalation, brought both elbows together while flexing the trunk muscles. During inhalation, the participant moved the elbows outward while extending the trunk to expand the chest wall. The trunk rotation exercise was performed from the same starting position as the chest expansion exercise. During exhalation, the participant rotated and flexed the trunk, lowering the elbow toward the opposite knee. During inhalation, the participant returned to the starting position. This exercise was performed alternately on both sides.
