Improving Stroke Motor Control With Non-invasive Brain Stimulation and Functional Electrical Stimulation

"Contralaterally Controlled Functional Electrical Stimulation: An electrical stimulator will be used to deliver electrical current through surface electrodes to produce hand opening by making the paretic finger and thumb extensor muscles contract. The stimulator will be programmed to deliver stimulation with an intensity that corresponds to the opening of a glove instrumented with sensors and plugged into the stimulator (i.e., CCFES).~Transcranial direct current stimulation (tDCS): TDCS is a method of noninvasive stimulation of the brain. Using electrodes placed in saline-soaked sponges, low level of direct current (1mA) is delivered over the scalp. This intervention is considered safe and noninvasive because it does not involve implantation or injection or any skin penetration."
