Description of intervention(s) / exposure
1. Motor control training combined with MTrP therapy include (1) manual compression on MTrPs of shoulder muscles (levator scapulae, pectoralis minor, infraspinatus, teres minor, trapezius, rhomboids), each point for 30-60 sec, 2-3 repetitions. MTrP treatment was administered by each patient's physical therapist. (2) Immediately after the MTrp treatment, shoulder range of motion exercise with stretching to achieve maximum painfree shoulder flexion, abduction, internal and external rotation was performed. (3) Shoulder motor control retraining: Patients were instructed to maintain a scapular neutral position and consequently taught to find the neutral position themselves. Patients were shown and told to avoid several incorrect muscle activation strategies. The patient was asked to control the orientation of the scapula whilst performing arm flexion to 90° in the sagittal plane, arm abduction to 60° in the scapular plane and arm medial rotation to 60°. Movements were performed 3 sets of 10 repetitions for each direction. Once scapular control had improved, external resistance exercises with a light weight or a thera-band were added to the program. Same exercise intensity (3 sets of 10 repetitions for each direction) was used. The duration of the exercise and MTrP therapy within each session was about 1 hour.
2. The socio-demographic data, occupational factors, characteristics of shoulder complaints, shoulder aberrant movements, pressure pain threshold, and shoulder range of motion will be evaluated as potential prognostic factors. All patients will receive motor control exercises combined with MTrP therapy twice a week for 8 weeks or until patients achieve their goals.
