Experimental: Activity Training with Feedback
Subject is tested prior to training and retested with feedback training designed to modify the mechanics of landing during jumping and running activities
Device: Activity Training with Feedback
The feedback system consisted of three small inertial measurement units affixed on the chest, thigh, and shank segment respectively. These units were connected to a computer that recorded the signal from the inertial sensors at 240 Hz during the jump task. Using custom software, the knee flexion angle, trunk lean, and coronal thigh angular velocity were calculated immediately after the subject completed the jump trial. A projector was used to display the results of the jump analysis. It took less than 10 minutes to place this system on a subject and less than five seconds to analyze a jump.
- Knee Flexion Angle and Trunk Flexion Angle After Activity Training With Feedback [ Time Frame: 1 day ]Knee flexion angle describes the angle between the tibia and femur during the activity. Trunk flexion is the angle between the shoulders and the hips during the activity.
- Thigh Coronal Angular Velocity After Feedback Training [ Time Frame: 1 day ]How fast the thigh is moving relative to the tibia during the activity, measured in degrees/second.
