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.

Conditions

Appropriate Affect

Outcome Measures

Primary Outcomes (1)

• 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 Outcomes (2)

• Appropriate affect

  Immediately after the intervention

• Influence of patient's characteristic

  During the patient's inclusion / Baseline

Study Arms (1)

Upper limb amputee population

EXPERIMENTAL

Other: Modified illusion of the rubber (syncrhone); Other: Modified illusion of the rubber (asynchrone)

Interventions

Modified illusion of the rubber (syncrhone) OTHER

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.

Upper limb amputee population

Modified illusion of the rubber (asynchrone) OTHER

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.
