Several Studys Showed That Upper Limb Amputated Patients Are Able to Experience the Illusion of the Rubber Hand Whith Prosthesis: We Want to go Futher by Comparing the Strength of the Incorporation According to the Type of Prosthesis Using the Illusion of the Rubber Hand With Prothesis

Study Overview
=================
Brief Summary
-----------------
The goal of this observational study is to compare the strength of the incorporation according to the type of prosthesis (aesthetic, mechanical, myoelectric) with the experience the illusion of the rubber hand. The investigators will replace is the rubber by the patient's prothesis. The population will be people with upper arm amputation above the hand and they will be their own comparation. Participants will do the the experience the illusion of the rubber hand in asynchronic and synchronic way and to answer questionnaries.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Upper limb amputee population<br> | Other: Modified illusion of the rubber (syncrhone)<br>* The residual limb of the patient will be hide for the patient. The prothesis and the other hand of the patient will be visible. The investigators are going to touch the residual limb and the prothesis at the same time (synchrone) during at least 2 min. The investigators will ask to the patient to point where they felt the touching spot on a tray with measurement grid and to asnwer to the pre-prepared questionnaire.<br>Other: Modified illusion of the rubber (asynchrone)<br>* The residual limb of the patient will be hide for the patient. The prothesis and the other hand of the patient will be visible. The investigators are going to touch the residual limb and the prothesis not at the same time (asynchrone) during at least 2 min. The investigators will ask to the patient to point where they felt the touching spot on a tray with measurement grid and to asnwer to the pre-prepared questionnaire.<br>|

What is the study measuring?

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proprioceptive drift | Before and after each intervention, we are going to ask to the patient to point where we touch the residual limb on a graduated board. | Immediately after the intervention | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Appropriate affect | After each intervention, patient will answering to a questionnary about appropriation with their past as comparaison. | Immediately after the intervention | 
| Influence of patient's characteristic | Compare patient's characteristic with other outome : amputation level, time since amputation, time using the prothestics | During the patient's inclusion / Baseline |
