Conditions
Brief summary
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.
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.

Inclusion criteria
* 20 to 65 years old, which is the legal age range of adult for work in Taiwan * registered nurses to work full time in the hemodialysis unit more than 6 months, * having complaint of WMSDs within previous 6 months before this study.
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| severity degree of muscular discomfort | week 0 | self reported by Nordic Musculoskeletal Questionnaire (0-5 points; the higher score indicates the more discomfort) |
| muscle strength | week 0 | grip and pinch power; the muscle strength of neck extension, shoulder flexion/extension, and wrist flexion/extension of the dominant (maximal force of the muscles movement against in kilograms, the higher the stronger) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Subjective quality of life | week 0 | World Health Organization Quality of Life, Brief edition, Taiwan version (1-5, higher score for higher quality of life) |
