NCT05866003

Brief Summary

After a stroke, it is very common to lose the ability to open the affected hand. Occupational and physical rehabilitation therapy (OT and PT) combined with non-invasive brain stimulation may help a person recover hand movement. The purpose of this study is to compare 3 non-invasive brain stimulation protocols combined with therapy to see if they result in different amounts of recovery of hand movement after a stroke.

Outcome Measures

Primary Outcomes (1)

  • Box and Blocks Test (BBT)

    The BBT counts how many blocks a patient can pick up, move over a barrier, and release in 60 seconds.

    Change in BBT will be assessed at 6 weeks, 12 weeks, 24 weeks, and 36 weeks

Secondary Outcomes (1)

  • Upper Extremity Fugl-Meyer Assessment (UEFM).

    Change in UEFM will be assessed at 6 weeks, 12 weeks, 24 weeks, and 36 weeks

Other Outcomes (1)

  • Neurophysiologic Assessments

    Change in neurophysiologic assessments will be assessed at 6 weeks, 12 weeks, 24 weeks, and 36 weeks

Study Arms (3)

Active conventional tDCS plus CCFES

ACTIVE COMPARATOR

The conventional tDCS montages involves placing the surface anode electrode on the scalp of the lesioned hemisphere and the surface cathode electrode on the scalp of the non-lesioned hemisphere. TDCS will deliver a low current while participants are undergoing CCFES-mediated functional task practice.

Device: Active conventional tDCS montage plus CCFESBehavioral: CCFES with Occupational Therapy

Active unconventional tDCS plus CCFES

ACTIVE COMPARATOR

The unconventional tDCS montages involves placing the surface anode electrode on the scalp of the non-lesioned hemisphere and the surface cathode electrode on the scalp of the lesioned hemisphere. TDCS will deliver a low current while participants are undergoing CCFES-mediated functional task practice.

Sham tDCS plus CCFES

SHAM COMPARATOR

The sham tDCS montages involves placing the surface electrodes on the scalp over the lesioned and the non-lesioned hemisphere. TDCS will not be delivered during CCFES-mediated functional task practice.

Interventions

tDCS is a non-invasive brain stimulation technique. A small machine (9-volt battery operated device) will use a weak amount of electric current to stimulate the brain without any invasive procedure. Electrodes, covered in sponges soaked in saline, will be placed over certain parts of your head and held in place using a rubber strap. In addition, 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.

Active unconventional tDCS plus CCFES

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 can be programmed to deliver stimulation with an intensity that corresponds to the opening of a glove instrumented with sensors and plugged into the stimulator.

The stimulator can be programmed to deliver stimulation with an intensity that corresponds to the opening of a glove instrumented with sensors and plugged into the stimulator. During the lab visits, all participants will use CCFES to assist hand opening during occupational therapy task practice.
