Summary

Pinch grip muscle engagement varies with exerted force. Both force and position are crucial for assessing pinch grip as a risk factor for upper limb biomechanical overload.

Area of Science:

  • Occupational health and safety
  • Biomechanics
  • Ergonomics

Background:

  • Ergonomic evaluations sometimes consider pinch grip a risk factor irrespective of force.
  • Objective measurement of muscle activity during pinch grip is essential for accurate risk assessment.

Purpose of the Study:

  • To objectively measure muscle engagement during pinch grip execution.
  • To investigate the relationship between exerted force and muscle activity in pinch grip tasks.

Main Methods:

  • Surface electromyography (sEMG) measured activity in abductor pollicis brevis (ABP) and first dorsal interosseous (FDI) muscles.
  • Participants performed maximum voluntary isometric contractions (MVIC) and submaximal contractions (10%, 20%, 50% MVIC).
  • Muscle activity was also assessed while holding envelopes of 100g and 500g.

Main Results:

  • Holding 100g and 500g envelopes required 4% and 5% MVIC, respectively.
  • Corresponding sEMG activity was ~6% MVIC for FDI and ~20-25% MVIC for ABP.
  • Significant correlations were found between MVIC force and FDI activity.

Conclusions:

  • Muscle recruitment during pinch grip is force-dependent.
  • Assessing pinch grip as a risk factor requires considering both the exerted force and the grip position.
