Biofeedback After Stroke

Официальное название

Use of Electromyographic Biofeedback in Upper Limb Rehabilitation After Stroke

Обзор

Studies show that the use of electromyographic biofeedback combined with other therapies contributes to the reduction of upper limb spasticity after stroke. However, there is a lack of literature regarding the best protocols to use in clinical practice, as well as functional outcomes after this therapy. The objective of this research project will be to investigate the effect of electromyographic biofeedback on spasticity in individuals post-stroke in the sub-acute phase, and its outcomes regarding upper limb function and participation in activities of daily living. The study will be a randomized, triple-blind clinical trial in which the 45 participants will be divided into two groups: the experimental group will receive electromyographic biofeedback combined with functional training, and the control group will receive functional training with placebo biofeedback alone. The study hypothesis is that the use of electromyographic biofeedback contributes to improved functional outcomes and participation in activities of daily living in patients with upper limb spasticity resulting from stroke.

Вмешательства

• Устройство Electromyographic Biofeedback
  This intervention phase will last 30 minutes of training, during which the participant will be encouraged to actively and voluntarily relax their spastic muscles and will receive visual feedback through the software when this occurs. Two modes will be used in the software: the first, called "Recovery", which consists of a game in which the participant is encouraged to contract and relax their muscles in order to guide a rocket in a specific direction to earn points. The second, called "Maestro",
• Устройство Sham (No Treatment)
  The intervention with the placebo group will have an identical structure to that of the intervention group, but during the biofeedback phase, the software screen will be a simulation, not corresponding to the patient's muscle activity. The patient will receive occupational therapy as usual, in a manner identical to that of the intervention group after the placebo biofeedback therapy.
