Short Interventions to Prevent Trapezius Muscle Fatigue in Computer Work

NCT03863340 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 30

No results posted yet for this study

Summary

This study is expected to demonstrate that during experimental days of seated computer work sustained and focalized low-level muscle activity contributes to the development of long-lasting fatigue effects (and thus possible disorder). On days with and without frequent interruptions, signs of fatigue and the activity pattern of the trapeze muscle are registered and compared using electromyographic registrations of the trapezius muscle.

Conditions

  • Muscle Fatigue
  • Trapezius Muscle Strain

Interventions

BEHAVIORAL

interruptions of work tasks

During each activity two interruptions/breaks were selected randomly from a set of ten predetermined actions: Active break types: * Move shoulder and upper back * Swing arms near the body * Three slow but forceful elevations of the shoulders, a relaxation exercise based on the principles developed by Jacobson * Stand up and stretch * Slowly turn head in all possible directions. Passive break types: * Tell a couple of jokes * Stand up and have a drink * Relaxing the trapezius * Questions on actual posture and feelings of comfort / discomfort. * A short rest on the couch
