virtual reality in physical therapy in multiple sclerosis

Conditions: Multiple Sclerosis

Summary: the randomized controlled trial is aimed to study the efficacy of virtual reality (vr) and its impact on upper limb function and postural stability in people with mild to severe multiple sclerosis (pwms). the conceptual idea is to compare two kinds of neuroproprioceptive "facilitation and inhibition" physical therapy, first in a real environment and second in virtual reality, in out-patient therapy that will be held in 15 hourly therapies, 2x a week in a period of two months. the efficacy will be assessed by a blinded independent clinical examiner using clinical examination and questionnaire survey before and in a week following the therapeutic intervention. the main focus is on upper limb gross and fine motor skills, trunk stability and stability, and sit to stand stability.

in 60 - 75% of people with multiple sclerosis (ms) an upper limb mobility dysfunction (unilateral or bilateral manual dexterity, sensibility impairment, tremor) is present, resulting in reduced participation in activities of daily living. physiotherapy has a crucial impact on upper limb mobility, although there are many approaches applied (exercise/strengthening exercise, endurance training, sensory training, constraint-induced movement therapy, robotic rehabilitation therapy, etc.). virtual reality is an innovative technological concept using game mechanisms that facilitate concentration and motivation in task performance. current research implies that vr is a safe and effective method in gait and balance//stability rehabilitation therapy and with less evidence, for upper limb mobility improvement. it is expected that a greater therapeutic effect is a result of multifactorial sense stimulation and dopamine centres in the brain. a pilot project showed that virtual reality without the prompt feedback of a physiotherapist is not more effective than standard therapy. a new therapeutic software using virtual reality spontaneously motivating the patient for movement realization was developed in cooperation with the department of informatics and computer science faculty of applied sciences university west bohemia. accurate execution of neuroproprioceptive "facilitation and inhibition techniques" physical therapy combining key principles from proprioceptive neuromuscular stabilization (pns) and motor program activating therapy (mpat), ensures a present physiotherapist. these principles have shown the effect in therapy in pwms. participants will be randomized into two arms of the study, both implementing neuroproprioceptive "facilitation and inhibition" physical therapy, first in a real environment and second in vr. the investigators expect that vr intervention shall improve upper limb motor functions, trunk muscles coordination, improve the performance of activities of daily living and quality of life in pwms more than identical therapy not using vr. the effect of both interventions will be assessed using validated tests for clinical examination- five times sit to stand test (5sts), nine hole peg test (9hpt), hand grip strength (hgs), box and block test (bnb), accelerometer for tremor examination. validated questionnaires will be used, specifically the multiple sclerosis impact scale (msis-29), eq-5d-3l health questionnaire, visual analogue scale, and a questionnaire dealing with individual virtual reality intervention evaluation.
