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 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.\n\nParticipants 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.\n\nFindings 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.",[75,76,77],"Chronic Neck Pain","Neck Pain Treatment","Neck Pain Chronic",[79,80,81,82,83,84,85,86,87,88,89,90],"endurance exercise","endurance training","endurance","stretching","stretching exercise","neck pain","neck-shoulder pain","chronic neck pain","chronic neck-shoulder pain","pain","pressure pain","muscle stiffness","NOT_YET_RECRUITING","2024-11-19",{"date":94,"type":95},"2024-11-21","ACTUAL",{"date":97,"type":69},"2024-11",{"date":99,"type":69},"2025-03",{"name":5,"class":6},1]
