What this trial studies

This study aims to evaluate how a wearable sensor can detect changes in knee joint loading by simulating knee joint effusion, a common condition affecting joint status. It will involve a cross-sectional cohort design with 25 healthy adults aged 18-35 who will participate in three sessions: informed consent and familiarization, testing, and knee joint status assessment. The primary outcomes will include data on lower extremity acceleration, velocity, and 3D kinematics and kinetics, collected through motion capture and wearable sensors.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy adults aged 18-35 who are physically active and have a Tegner Activity Scale score of at least 5.

Not a fit: Patients with a history of lower extremity injuries, surgeries, or current knee pain may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to a cost-effective method for monitoring knee joint health and biomechanics in patients with knee injuries or osteoarthritis.

How similar studies have performed: While this approach is innovative, similar studies using wearable sensors for biomechanical assessments have shown promise in other contexts.
