Summary

High intensity shoulder contractions did not affect computer worker productivity or perceived exertion. However, these contractions reduced rest time in the upper trapezius muscle during pauses, warranting further investigation for pain prevention strategies.

Area of Science:

  • Ergonomics
  • Occupational Health
  • Muscle Physiology

Background:

  • Work-site strength training is effective for neck-shoulder pain but difficult to integrate.
  • High intensity voluntary contractions during computer work may offer a solution.
  • The impact of these contractions on productivity and muscle activity is unknown.

Purpose of the Study:

  • To investigate the short-term effects of high intensity contraction on productivity, perceived exertion, and upper trapezius muscle activity and rest.
  • To assess these effects during computer work and a subsequent pause.

Main Methods:

  • 18 female computer workers participated in two 15-minute computer mouse work sessions.
  • Sessions were preceded by a 1-minute pause, with and without a 1-minute high intensity shoulder elevation contraction.

Biomechanical Changes Related to Low Back Pain: An Innovative Tool for Movement Pattern Assessment and Treatment Evaluation in Rehabilitation

Published on: December 13, 2024

  • Productivity, rate of perceived exertion (RPE), and upper trapezius electromyography (EMG) were measured.

    • Main Results:

    • High intensity shoulder elevation did not alter RPE or productivity during the pause or computer work.
    • No significant changes in upper trapezius EMG activity were observed.
    • A significant reduction in relative rest time of the clavicular trapezius was noted (p < 0.04).

    Conclusions:

    • Implementing high intensity contractions during computer work may be feasible without negatively impacting productivity or perceived effort.
    • The reduction in clavicular trapezius rest requires further study before recommending high intensity shoulder elevations.
    • Further research is needed to confirm the efficacy and safety of integrating high intensity contractions into computer work routines for pain prevention.
