Official title:
The Immediate Effect of Electrical Stimulation Transcranial Direct Current (tDCS) Associated With the Use of FES, in Muscle Activity of the Tibialis Anterior Muscle, Balance and Plantar Pressure Distribution of Individuals With Hemiparesis Due to Stroke - Randomized, Double Blind

Status Completed

Clinical Trial Summary

Background: Transcranial direct current stimulation (tDCS) is currently considered a beneficial method for patients with neurological problems due to the modulation of cortex activity as well as the enhancement and prolongation of functional gains achieved during physical therapy. Purpose: The aim of the proposed study is to evaluate the immediate effects of a session of tDCS over the primary motor cortex combined with functional electrical simulation (FES) on electrical activity of the tibialis anterior muscle, balance and distribution of plantar pressure in individuals with hemiparesis stemming from a stroke. A further aim is to determine whether the effects of the combination of both stimulation methods are better than those achieved when each method is employed alone. Methods/design: A randomized, double-blind, crossover, cross-sectional study will be conducted involving 30 stroke survivors with hemiparesis who meet the eligibility criteria. Evaluations will involve an identification and screening chart, the classification of motor impairment using the Fugl-Meyer Scale, the determination of spasticity of the triceps surae muscle (modified Ashworth scale), electromyography of the tibialis anterior muscle, static balance and cognitive dual-task balance (stabilometry) and plantar pressure. After the initial evaluations, the participants will undergo four interventions: 1) anodal tDCS + placebo FES + active tibialis anterior contraction; 2) placebo tDCS + active FES + active tibialis anterior contraction; 3) anodal tDCS + active FES + active tibialis anterior contraction; and 4) placebo tDCS + placebo FES placebo + active tibialis anterior contraction. tDCS will be administered over the primary motor cortex and FES will be administered over the tibialis anterior muscle. The order of the different protocols will be randomized and both the evaluator and patients will be blinded to which protocol is being administered.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
