- Registration Number
- NCT04144764
- Lead Sponsor
- Chinese University of Hong Kong
- Brief Summary
Objectives: (1) To examine the upper trapezius muscle stiffness using SSI in workers with and without neck/shoulder disorders; and (2) to develop a workplace-based exercise programme to reduce upper trapezius muscle stiffness and to enhance shoulder function and work ability in the working population.
Hypotheses to be tested: (1) Workers with neck/shoulder disorders demonstrate increase upper trapezius muscle stiffness when compared to healthy control; and a cutoff value of the upper trapezius stiffness was established for early identification of individuals at risk of having neck/shoulder disorders in the working population; (2) Workplace-based exercise programme can reduce upper trapezius muscle stiffness and enhance shoulder function and work ability in the working population.
Design: Part A study: Cross-sectional study; Part B study: randomized controlled trial
Subjects: One-hundred office computer workers with or without neck/shoulder pain
Study instruments: Supersonic shear wave imaging
Main outcome measures: Upper trapezius muscle stiffness, Shoulder Pain and Disability Index (SPADI), Neck Disability Index, Disability of the Arm, Shoulder and Hand (DASH), work ability index (WAI).
Data analysis: Between-group comparisons to show differences in the outcome measures will be analyzed using Independent t-test. To compare the treatment effects, repeated-measures analysis of variance test (between-group factor: intervention vs control; within-subject factor: time (baseline, 6 week and 1 year)).
Expected results: Workers with neck/shoulder disorders demonstrate increase upper trapezius muscle stiffness when compared to healthy control. Workplace-based exercise programme can reduce upper trapezius muscle stiffness and enhance shoulder function and work ability in the working population.

- Primary Outcome Measures
Name Time Method Change in Upper trapezius muscle stiffness 0, 10-weeks and 1-year Supersonic shear wave imaging of the upper trapezius muscles
- Secondary Outcome Measures
Name Time Method Change in Shoulder Pain and Disability Score 0, 10-weeks and 1-year The Chinese Version of the Shoulder Pain and Disability Index (SPADI) questionnaire is a validated self-administered questionnaire to evaluate the shoulder pain and disability scores. The questionnaire consists of 13 items with 2 subscales: pain (5 items) and disability (8 items); and the total final score that range from 0 to 100, with higher scores indicate more disability.
Change in Functional score 0, 10-weeks and 1-year The Chinese Version of the Neck Disability Index and Disability of the Arm, Shoulder and Hand (DASH-HKPWH) questionnaire are reliable and validated self-administered questionnaire to evaluate the neck and upper extremity function. The total score is divided by number of answered questions, subtracted 1 and multiplied by 25, in a scale score that range from 0 to 100, with higher scale scores indicate more disability.
Change in Work ability 0, 10-weeks and 1-year The work ability index (WAI) questionnaire will be used to evaluate the work ability. It composes of 7 items that evaluate: 1) current work ability compared with lifetime best; 2) work ability in relation to job demand; 3) number of current diagnosed disorders; 4) estimated work impairment due to disease; 5) sick leave during the past 12 months; 6) own prognosis of work ability; and 7) mental capacities. The score ranged between 7 to 49, with higher scores indicate better work ability.
