The comparison of the effects of myofascial trigger point therapy with neck-specific exercises and general exercises in office workers with non-specific neck pain

The intervention group will receive myofascial trigger point therapy by a physical therapist once a week for 4 weeks. The physical therapist will apply moderate compression on subjects' three most uncomfortable trigger points (according to trigger point assessment) for 60 seconds. Then subjects will perform the neck-specific exercises including stretching exercises for levator scapulae, anterior scalene, infraspinatus, pectoralis minor, sternocleidomastoid and neck extensors as well as strengthening exercise of the upper trapezius. The total treatment time will be 30 minutes per session. Subjects will be informed to do a 15-minute home program including ball massage and exercises (same as the intervention exposure) three times a week for 4 weeks. The therapist will monitor adherence to the intervention by participant diary and mobile phone message reminders (twice a week).
