Seeing if your sense of grip force stays consistent after one week
Test-Retest Reliability of Grip Force Sense for Proprioception Assessment in Healthy Participants
This test will try to see if a handheld dynamometer can reliably show how accurately healthy young adults reproduce grip force across two sessions one week apart.

What this trial studies
Healthy volunteers aged 18-24 perform isometric grip force reproduction tasks using a digital hand dynamometer. Each participant completes nine trials (three repetitions at 10%, 30%, and 50% of MVIC) in two sessions separated by seven days, conducted in the same lab by the same researcher. Grip force accuracy is recorded from a digital monitor and quantified using absolute error (AE), constant error (CE), and variable error (VE). Results will be summarized with means, standard deviations and ranges for continuous data and frequencies/percentages for categorical data.
Who should consider this trial
Good fit: Healthy adults aged 18-24 without current hand pain or a history of hand surgery who can attend two sessions one week apart.
Not a fit: People with active hand pathology, ongoing hand pain, or prior hand surgery are excluded and unlikely to benefit from this protocol.
Why it matters
Potential benefit: If successful, this could provide a simple, clinic-friendly way to monitor proprioceptive grip-force accuracy over time.
How similar studies have performed: Similar dynamometer-based force reproduction methods have been used previously with variable but generally acceptable reliability, so this protocol builds on existing approaches while focusing on test-retest repeatability in young adults.
