Summary

The aim of our study is to compare the effects of different stretching methods for the pectoralis minor (PM) muscle on scapula position, PM muscle length and scapular muscle activation in individuals with shoulder protraction. Unilateral corner stretching, manual stretching and proprioceptive neuromuscular facilitation (PNF) stretching methods will be applied randomly, 2 days apart, to volunteer individuals who agree to participate in our study. Three different stretching methods (unilateral corner stretching, manual stretching and PNF stretching) will be applied to individuals randomly, 48 hours apart, and PM length, PM index, scapula upward rotation and EMG values will be recorded by a blind evaluator before and after the stretching application.

Conditions

  • Rounded Shoulder Posture

Interventions

OTHER

Unilateral Corner Stretch

Individuals will be positioned in a standing position with the elbow in 90° flexion and the shoulder in 90° abduction, placing the palm on a flat surface. For stretching, individuals will be asked to increase shoulder horizontal abduction by rotating the trunk anteriorly and contralaterally. The position will be maintained for 30 seconds and will be repeated 4 times with a 30-second rest between repetitions.

OTHER

Manual Stretching

Individuals will be positioned supine with the shoulder in 90º abduction and external rotation and the elbow in 90º flexion. Stretching will be applied by the physiotherapist from just distal to the elbow in the direction of horizontal abduction of the shoulder. The position will be maintained for 30 seconds and will be repeated 4 times with a 30-second rest between repetitions.

OTHER

PNF Stretching

Individuals will be in a sitting position with their hands clasped behind the head. The PM muscle will be stretched in the direction of horizontal abduction by placing the physiotherapist's hands anterior to the elbows. Passive stretching will be continued for 10 seconds, followed by 6 seconds of maximum voluntary isometric contraction of the PM muscle. The procedure will be repeated four times with 30 seconds of rest.
