ABSTRACT
OBJECTIVE: To investigate the effects of visual feedback training on knee function and balance ability in postoperative patients with knee fracture. METHODS: A clinical randomized controlled trial with 104 participants, randomly assigned (1:1) to a visual feedback training group or a control group. Eligible participants were evaluated using Lysholm scores, the Tinetti scale, and the evaluation module of TecnoBody® to demonstrate dynamic balance function in a standing position before treatment and after 4 and 8 weeks of treatment. RESULTS: Both visual feedback training and control groups improved significantly in the Lysholm and Tinetti scores after 8 weeks. Compared with the control group, the TecnoBody® tests included centre of pressure path length, and the area over centre of pressure movement, both of which significantly improved in the visual feedback training group at 8 weeks after treatment. There was no difference between the 2 groups in terms of their Lysholm scores and Tinetti gait before the intervention and 4 weeks after treatment. CONCLUSION: Applying visual feedback training in conjunction with traditional rehabilitation strategies may improve knee function and motor control in postoperative patients with knee fracture. Although visual feedback training does not have a short-term effect on knee function and gait, this method could be a useful addition for rehabilitation of knee fracture patients.
