Is FDA regulated | No |
Health authority | |
Study type | Interventional |
The main objective of this pilot study is to determine if using a portable, accelerometer based, visual feedback system improves exercise quality. The secondary objective of this study is to investigate the effect of motivational targets by testing the effects of increasing ROM targets. The results from this study will be used to improve the visual feedback system of the Knee Connect system and serve as starting point for a larger clinical study.
