Quantification of Upper Trapezius Muscle Stiffness Using Supersonic Shear

Status Recruiting

Clinical Trial 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.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
