Effects of pectoralis minor stretching on resting muscle length and scapular kinematics during elevation of the arm in asymptomatics subjects and people with shoulder pain

Abstract

There are evidences that shortening of the pectoralis minor is an important factor of change in biomechanics and can influence scapular kinematics. The stretching of this muscle is one of the most widely used techniques in clinical practice as an attempt to decrease the pain and improve function in patients with shoulder pain. However, this is not usually the only technique used in the rehabilitation protocol. There is lack of studies that assess the real effectiveness of a stretching program for the pectoralis minor on its resting length and on scapular kinematics. Therefore, the purpose of this study is to verify the effects of a stretching protocol for the pectoralis minor muscle on its resting length and on the 3D kinematics of the scapula during arm flexion in asymptomatic subjects and patients with impingement syndrome with shortened pectoralis minor. Fifty subjects (25 symptomatic and 25 asymptomatic for shoulder pain) will be recruited. Ali of them will be initially assessed twice with one week between the assessments. On each day, they will complete two questionnaires (DASH and SPADI) to assess pain and shoulder function. The resting length of the pectoralis minor muscle and scapular kinematics data during arm flexion will also be measured using an electromagnetic tracking system. Initially, the resting length of the pectoralis minor will be measured, and then 3 repetitions of arm elevation in the sagittal plane will be completed. The stretching protocol will be performed daily for 6 weeks… (AU)
