Musculoskeletal Disorders, Stress
Conditions
Brief summary
Static postures, repetitive work tasks, and work stress increase the risk for musculoskeletal disorders and sickness absence. Objective measurements of occupational loadings - EMG for muscular activity, EEG for cognitive activity, ECG for cardiovascular activity and heart rate variability, actigraphy for bodily movements - may provide useful early indicators of muscular, cognitive and cardiovascular overload. The aim of this study is to investigate the effect of an individually tailored bio-psycho-social intervention strategy versus usual care ergonomics and standard physical exercises (reference group) on these risk factors in lab technicians with a history of work-related musculoskeletal pain.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| EMG gaps | change from baseline to week 10 | Electromyography (EMG) is measured in the neck and shoulder muscles throughout a normal workday before and after the intervention. EMG gaps is defined as periods with muscular inactivity. Actigraphs are used to measure bodily movements, and only period with sitting or standing work are included in the analysis (i.e. walking activities are excluded from the analyses) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| EEG | change from baseline to week 10 | Electroencephalography is measured throughout a normal workday before and after the intervention. Actigraphs are used to measure bodily movements, and only period with sitting or standing work are included in the analysis (i.e. walking activities are excluded from the analyses) |
| HRV | change from baseline til 10 week followup | Heart Rate Variability (HRV) is measured with Actiheart throughout the working day before and after the intervention. Actigraphs are used to measure bodily movements, and only period with sitting or standing work are included in the analysis (i.e. walking activities are excluded from the analyses) |
