The Effect of Low-load Endurance Training of Upper Trapezius on Pain, Pressure Pain and Muscle Stiffness in Chronic Neck-shoulder Pain Compared to Stretching Exercise
Sponsor: The Hong Kong Polytechnic University
Summary
This study aims to investigate the effectiveness of low-load endurance exercise as compared to stretching exercise on upper trapezius on pain, pressure pain and muscle stiffness in patients with chronic neck-shoulder pain. The hypothesis is that endurance exercise of the upper trapezius should result in significantly better improvement in terms of neck-shoulder pain, pressure pain threshold and muscle stiffness than stretching exercise. Participants with unilateral neck-shoulder pain will either perform low-load endurance exercise or stretching exercise of the upper trapezius muscle of the affected side in a 5-week period. Before and after the 5-week training, outcomes will be assessed by investigators in order to compare the effectiveness of two exercises on pain, pressure pain, muscle stiffness, and muscle endurance. Secondary outcomes include Neck Disability Index (NDI) to assess various aspects of daily living impacted by neck pain, and Disabilities of Shoulder, Arm and Hand (DASH) Questionnaire to evaluate the ability to perform various upper limb activities. Findings to be obtained from this study will help inform the clinical management in particular for self-care of this chronic neck pain group of participants, by refining the exercise prescription for promoting the clinical outcomes for individuals suffering from neck-shoulder pain. In addition, results of this study will also inform physiotherapists the possible mechanisms underlying the improvement of neck-shoulder pain by examination of the relationship between biomechanical properties of muscles, such as muscle endurance or muscle stiffness, and neck-shoulder pain.

Interventions
Upper trapezius low-load endurance exercise
Participants in the EE group will perform the overhead shrug exercise for the affected side using a green Thera-Band Elastic Band. To perform this exercise, the subject will stand and place one arm of the affected side in an overhead position against the wall. The middle portion of the theraband will be placed on the floor, and the subject will stand on the middle portion of the theraband to fixate it in place with both feet shoulder-width apart. Then, the subject grasp both tails of the theraband and perform the shoulder shrug movement for the affected side with a 3-second elevation, hold at the end range for 5 seconds, and then return back to the starting position with a 3-second depression. The subject will perform this exercise for 20 repetitions per set, 3 sets a day with 1-minute rest between sets, 3 alternate days a week, for 5 weeks. They will be instructed to record all training sessions in a diary.
Upper trapezius stretching exercise
Participants in the SE group will perform static upper trapezius stretching exercise for the affected side. To perform the stretch, participants will be asked to sit upright on a chair and look straight ahead. To reduce scapular elevation and upward rotation, the ipsilateral hand should be placed below the buttock. The subject will then be asked to perform deep neck flexion, neck rotation towards the affected side, and contralateral side flexion using the opposite hand in a diagonal direction until the position of 'mild discomfort' is attained. They should maintain the deep neck flexion when performing the stretch. The stretch will be held for 30 seconds each set, 3 sets a day, daily for 5 weeks.
