Pectoralis Minor Length and muscle endurance evaluation

PM length was measured with a caliper. The distance between the starting (origin) and ending (insertion) points of the PM muscle was measured, with the participant in supine position and the shoulder joint free.Pectoralis minor index (PMI) was obtained by dividing the PM length recorded in cm by the person's weight and multiplying the result by 100. PMI was determined by dividing the obtained value by weight

The lateral scapular slide test (LSST) was used to evaluate scapular dyskinesia. The distance between the inferior angle of the scapula and the closest vertebral spinous process in the standing upright position was bilaterally measured using a tape measure in three different positions

Scapular muscle endurance was evaluated with the scapular isometric compression test. The participants were asked to stand upright with their arms on their sides and bring both shoulder blades closer together by maintaining this position as long as they could

This evaluation was performed using McGill's torso muscular endurance test battery consisting of endurance tests in the trunk flexion, trunk extension (Sorensen), and right/left side bridge positions
