Study Summary
The goal of this clinical trial was to learn if a localized knee exercise program with visual and auditory feedback improves joint awareness (proprioception) and movement quality in young adults with a history of knee injuries. It also evaluated the feasibility and safety of performing these exercises. The main questions it aimed to answer were: 1. Does targeted knee training with instant audio and visual warnings improve joint position awareness and decrease movement fear? 2. Is a supervised laboratory biofeedback training program more effective at improving knee function and movement consistency than an independent home training program? 3. How reliable is a manual goniometer compared to an isokinetic machine when measuring joint position errors? Researchers used a crossover design where every participant completed both the home-based training program and the laboratory-based biofeedback program, separated by a two-week rest period, to compare the effectiveness of the two approaches. Participants did: 1. Complete two separate three-week training blocks (two sessions per week) performing squats, lunge patterns, and sidesteps. 2. Attend testing sessions at the lab before and after each training block to evaluate balance, movement consistency, and joint position awareness. 3. Wear smart shoe insoles and surface body sensors during testing and laboratory training to track force and joint angles. 4. Keep a log of exercises and note any side effects when training independently at home.
Primary Outcome
The Dispersion Index measures lower-limb joint coordination and movement consistency across the final 10 tapping repetitions of the APC task. Joint angle time-series data extracted from surface IMU sensors are used to construct a knee-hip angle-angle graph. Polar coordinate angles are calculated throughout the time series and normalized to 100% of the movement cycle. The spread of the polar coordinate angles is determined by calculating the difference between the maximum and minimum values at ev
