Brief Summary

The aim of this study is to investigate the test-retest reliability of the grip force sense, a component of proprioception, using a dynamometer that is easily accessible and usable in a clinical setting. This provides an accessible assessment method for research in the field of proprioception.

Conditions

Healthy Volunteers

Outcome Measures

Primary Outcomes (3)

• Absolute Error (AE)

  Absolute Error (AE) represents the absolute difference between the target force and the reproduced force, without regard to direction. It reflects the overall accuracy of the force reproduction task.

  Baseline and 1 week

• Constant Error (CE)

  Constant Error (CE) represents the directional difference between the target force and the reproduced force. It indicates the participant's directional bias (overshooting or undershooting the target).

  Baseline and 1 week

• Variable Error (VE)

  Variable Error (VE) represents the variability or consistency of the participant's performance across trials, regardless of the target. It reflects the consistency of force reproduction.

  Baseline and 1 week

Study Arms (1)

All Participants

Healthy volunteers. All participants will be assessed at baseline and re-assessed after a 1-week interval to determine test-retest reliability.

Eligibility Criteria

• Age: 18 Years - 24 Years
• Sex: all
