Abstract
|
|
|
Background: Approximately 30% of people suffer from chronic neck and shoulder pain. Chronic neck and shoulder pain arise due to the exposure to continuous low loading and monotonous work. This is a common musculoskeletal disorder in a society. As physical therapists, we should give appropriate treatment to these people.
Methods: A total of 26 patients with chronic neck and shoulder myalgia were randomly allocated into two experimental groups. First, 13 patients received shoulder strength training, while the other 13 patients received cervical mobilization. Outcome measures included bilateral pressure pain threshold by using an algometer at upper trapezius, visual analogue scale (VAS) to express their pain scale, and muscle tension by using myoton pro device pre-intervention and after the final treatment.
Results: The VAS and muscle tension in upper trapezius significantly decreased (p<.05) in both groups; however, no differences between two groups were observed (p>.05). The pressure pain threshold in upper trapezius significantly increased (p<.05) in both groups; yet, again, the differences between the groups did not reach statistical significance (p>.05).
Conclusion: As methods of treatment, shoulder-specific strength training and cervical mobilization can be appropriate approaches to the treatment of neck and shoulder musculoskeletal disorder.
