The trunk assists arm movements during reaching tasks, especially for distant targets. Trunk motion integrates smoothly, contributing to hand positioning and stabilizing posture.

Area of Science:

  • Human Movement Science
  • Biomechanics
  • Neuroscience

Background:

  • Reaching movements involve complex coordination between multiple body segments.
  • The role of trunk movement in unconstrained reaching is not fully understood.

Purpose of the Study:

  • To investigate the coordination between trunk and arm movements during unrestrained pointing.
  • To determine when and how the trunk contributes to reaching distant targets.

Main Methods:

  • Six subjects performed pointing movements to various target locations.
  • Kinematic data of trunk, arm, and scapular motion were analyzed.

Main Results:

  • Trunk participation increased for targets beyond arm's length.

  • Trunk motion initiated simultaneously with arm movement and continued until target contact.
  • Trunk motion integrated smoothly, influencing final hand positioning without altering joint coupling or hand path smoothness.

    • Conclusions:

    • The trunk acts as a postural stabilizer and an integral component in positioning the hand during reaching, particularly for targets requiring extensive reach.
    • Trunk flexion plays a crucial role in the terminal phase of reaching for distant targets.
