Evaluation of the Effectiveness of a Muscular Strengthening Protocol With an Instrumented Orthosis for Gonarthrosis Patients

The management of knee osteoarthritis via a physical activity protocol for rehabilitation has convincing results. However, the effectiveness of these protocols could be improved with a connected instrumented knee brace with an exercise protocol adapted for the patient which is supervise by an online physiotherapist to check the progression during home-based rehabilitation.

The management of knee osteoarthritis via physical activity protocol for rehabilitation has convincing results. The aim of this study is to determine the improvement of the effectiveness of a home-based rehabilitation with and without instrumented knee brace for moderated gonarthrosis patients.

The study will focus during one years on 80 moderated gonarthrosis patients with a Kellgren and Lawrence (K&L) score between 2 and 3, aged between 50 and 80. Each patient will practice an 8 weeks progressive home exercise program with 3 session per weeks. The effectiveness of this protocol will be quantified with a gait analysis with kinematics, kinetics and electromyography, before and after the progressive home exercise protocol. The statistical analysis will focus on ANOVA and correlation between control group and instrumented knee brace group.
