About this study
Official title: Optimization of the Role of Action Observation in the Post-operative Rehabilitation of the Total Knee Prosthesis
The LOARAL 2 project concerns patients who have undergone total knee arthroplasty to treat symptomatic osteoarthritis. Patient will be divided into three groups: a control group where patients will do standard rehabilitation associated with the judgments of videos represented non-human action and two experimental groups where patients will do standard rehabilitation associated with the judgement of human point-light display. The aim of this study is to measure the benefits of attentional focus and sex correspondence in the use of point-light display for the rehabilitation of patients with a total arthroplasty of the knee.

- Knee Surgery, Rehabilitation, Point Light Display
