Benefits of Observing Point-light Displays in Postoperative Rehabilitation of the Total Knee Prosthesis.

Study Overview
=================
Brief Summary
-----------------
The LOARAL project concerns patients who have undergone total knee arthroplasty to treat symptomatic osteoarthritis. Patient will be divided into two groups: a control group where patients will do standard rehabilitation and an experimental group where patients will do standard rehabilitation associated with the judgement of point-light display. The aim of this study is to validate the use of point-light display for the Rehabilitation of patients with a totalarthroplasty of the knee.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Compare the evaluation of the point light display relative to conventional rehabilitation | The time to realize the time up and go test will be assessed at inclusion and at the end of the program. | Rehabilitation during 3 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Compare the evaluation of the point light display on functional recovery | Test score the time up and go and test score questionnary WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index, Bellamy et al., 1988). | At the end of the program (3 weeks max) | 
| Compare the evaluation of the point light display on the detection and action recognition | Percentages of correct recognition of actions on the point light display | At the end of the program (3 weeks max) | 
| Compare the evaluation of the point light display on the feeling of self-efficacy personal | Test score questionnary of self-efficacy personal (Dumont et al., 2000). | At the end of the program (3 weeks max) |
