Training in the Use of Myoelectric Prostheses Through the Combined Application of Immersive Virtual Reality, Cross-education, and Mirror Therapy

Abstract

ABSTRACT Introduction During the rehabilitation process (RHB) of the patient with traumatic upper-limb amputation, the use of immersive virtual reality (IVR) facilitates the incorporation of the prosthesis into the body schema. This reinforces and enhances sensorimotor and cognitive stimulation to improve motor learning and motor patterns, while normalizing global gestures. Objectives The aims of this study were to implement retraining of gestural acquisition and prosthetic control in patients with upper-limb injuries and amputations through IVR, and to then incorporate this in the normalization of functional patterns in activities of daily living (ADLs) with the work of “cross-education” as well as the therapy of observation of actions—mirror therapy to enhance the joint effect of the approach with IVR. Methods Standard sessions were established for transradial and transhumeral trauma patients with upper-limb amputation and traumatic injuries within the rehabilitation treatment. During the sessions, games and virtual environment were used. The software ran in desktop mode using a “Leap Motion” or for immersive versions of 3D glasses (Oculus Rift S). Results The application of IVR in combination with conventional treatment obtained significant benefits for functionality. These included learning correct motor execution as well as motivational and emotional state with distal traumatic injuries and upper-limb amputations with or without myoelectric prosthesis, obtaining 5.6 on average on the GROC (global rating of change) scale. Conclusions Immersive virtual reality shows benefit for the normalization of motor learning of functional patterns in DLA and on the emotional, motivational level of the patient. Clinical Relevance The integrated combination of cross-education, mirror therapy, and immersive virtual reality may represent greater acquisition of motor patterns in the prosthetic training of patients with upper-limb amputation.
