Implementation of Physical Exercise at the Workplace (IRMA10) - Occupational Load

Not Applicable

Completed

• Conditions: Musculoskeletal Disorders; Stress
• Interventions: Behavioral: Biopsychosocial; Behavioral: Reference

• Registration Number: NCT02047682
• Lead Sponsor: National Research Centre for the Working Environment, Denmark

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.

Arm && Interventions

Group	Intervention	Description
Biopsychosocial	Biopsychosocial	Biopsychosocial intervention with Individually tailored physical exercises and stress management
Reference	Reference	Reference group receiving "usual care" in terms of standard workplace ergonomics and physical exercises

Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
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)
