Is this trial a fit for you?
✓Likely a good fit
Healthy adults aged 18 years or older without neurological disorders, significant musculoskeletal injuries, or cardiorespiratory disease are ideal candidates.
✕Probably not a fit
People with neurological disorders, prior musculoskeletal injuries that affect movement, or cardiorespiratory conditions are excluded and unlikely to benefit from participation.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is an interventional cross-sectional experiment in healthy adults that applies non-invasive vibration to the hamstring (tendon) and compares knee flexion and extension movements with and without vibration. Participants will perform isometric and concentric knee contractions while investigators record muscle activity and knee angular trajectories and velocities. The team hypothesizes that vibration will increase hamstring (flexor) activity and decrease quadriceps (extensor) activity, producing measurable changes in movement trajectories and speed. Results will be compared across conditions to quantify the immediate effect of tendon vibration on somatosensory input and motor performance.
Why it matters
Potential benefit: If successful, this could point to a simple non-invasive way to modify proprioceptive input and influence knee motor control that may inform rehabilitation approaches.
How similar studies have gone: Previous laboratory studies using tendon vibration have reliably altered muscle activation patterns and proprioceptive perception, so this approach builds on established experimental findings.
