Dynamic Balance in Unilateral Transtibial Amputees Following Virtual Reality Versus Conventional Rehabilitation

Обзор

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.

Вмешательства

• Другое Virtual Reality
  A 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
• Другое Standard rehabilitation
  A 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.
