Amputation causes somatic and psychological damage. Prognostic factors for postoperative gait recovery include the need for proprioceptive re-education for dynamic balance. Improved gait patterns and use of the prosthesis contribute to an overall improvement in the amputee's autonomy. Virtual reality coupled with movement analysis allows personalization of treatment with objective assessment of progress.
The study authors hypothesize that a virtual reality protocol for the dynamic balance of a unilateral transtibial amputee in initial rehabilitation will improve the dynamic balance assessment criteria compared with a conventional rehabilitation protocol.
Unilateral transtibial amputees in hospitalized in the rehabilitation of the musculoskeletal system service
All etiologies: vascular, traumatic and septic.
Adapted vascular equipment validated by physician.
Able to walk for 5 minutes on a treadmill without technical assistance.
The subject is participating in an interventional study or one involving a drug or medical device, or is in a period of exclusion determined by a previous study
Patient already included in the present study.
The subject refuses to or is unable to sign the consent
It is impossible to give the subject informed information
Parallel
Virtual Reality
Other interventionA progressive rehabilitation protocol (different levels according to success scores) consisting of several exercises using virtual and augmented reality with mechanical perturbations (pitching of the treadmill), interaction with the virtual environment, interaction with the virtual environment and augmented reality (projection of obstacles on the treadmill), and modification of the gait pattern with visual and/or audio biofeedback
Standard rehabilitation
Other interventionA treadmill walking protocol with virtual reality to immerse the patient in a 3 x 5-minute walking session, without visual, mechanical or auditory disturbances, and without prompting the patient to modify their walking pattern.
