Clinical Trial 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.

Intervention

Other:
• Modified illusion of the rubber (syncrhone)
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.
• Modified illusion of the rubber (asynchrone)
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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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	Appropriate affect	After each intervention, patient will answering to a questionnary about appropriation with their past as comparaison.	Immediately after the intervention
Secondary	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
