Study Description

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.

Musculoskeletal Disorders	Other: ergonomic training	Not Applicable

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.

Experimental: Ergonomic training group; The ergonomic training group received a 12-week ergonomic training program.	Other: ergonomic training; ergonomic education & exercise training
No Intervention: No training group; The no training group did not receive any training program.

Outcome Measures

Primary Outcome Measures :

1. severity degree of muscular discomfort [ Time Frame: week 0 ]
   self reported by Nordic Musculoskeletal Questionnaire (0-5 points; the higher score indicates the more discomfort)
2. muscle strength [ Time Frame: 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)
3. severity degree of muscular discomfort [ Time Frame: week 12 ]
   self reported by Nordic Musculoskeletal Questionnaire (0-5 points; the higher score indicates the more discomfort)
4. muscle strength [ Time Frame: week 12 ]
   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)
5. severity degree of muscular discomfort [ Time Frame: week 24 ]
   self reported by Nordic Musculoskeletal Questionnaire (0-5 points; the higher score indicates the more discomfort)
6. muscle strength [ Time Frame: week 24 ]
   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 kilogram, the higher the stronger)

Secondary Outcome Measures :

1. Subjective quality of life [ Time Frame: week 0 ]
   World Health Organization Quality of Life, Brief edition, Taiwan version (1-5, higher score for higher quality of life)
2. Subjective quality of life [ Time Frame: week 24 ]
   World Health Organization Quality of Life, Brief edition, Taiwan version (1-5, higher score for higher quality of life)
