An Ergonomic Training With Exercise Program for Work-related Musculoskeletal Disorders Among Hemodialysis Nurse (WMSD)

Occupational Therapy for Work-related Musculoskeletal Disorders Among Hemodialysis Nurse

This study aimed to examine the effectiveness of the 12-week ergonomic intervention developed by Person-Environment-Occupation (PEO) model in improving musculoskeletal discomfort and muscle strength for hemodialysis nurses. The maintenance effects of the intervention were also evaluated after another 12-week follow-up.

Study Overview

• Status: Completed
• Conditions: Musculoskeletal Disorders
• Intervention / Treatment: Other: ergonomic training

Detailed Description

Methods A cluster experimental design was used to conduct this study. Participants were recruited from hemodialysis units at two medical centers in Taiwan and had complaints of work-related musculoskeletal disorders (WMSDs) within the past six months. By PEO model, the 12-week intervention including ergonomic education and exercise program was designed based on the job contents of hemodialysis nurses. In the study period, we used a mobile massager app to reminder them and monitor their implementation of exercises. The outcome indicators were measured before and after intervention as well as the follow-up after another 12 weeks. A generalized estimating equations model was adopted to analyze the repeated measurements.
