Brief Summary:
The purpose of this study is to find out what are the best settings for applying electrical nerve stimulation over the skin for the short-term improvement of hand dysfunction after a stroke. The ultimate goal is to some day design an effective long-term training program to help someone recovery their ability to use their hands and function independently at home and in society. In order to know how to apply electrical nerve stimulation to produce a good long-term effect on hand dysfunction, we first need to know how to make it work best in the short-term, and improve our understanding of for whom it works and how it works.We will use a commercially available transcutaneous electrical nerve stimulation (TENS) unit to gently apply electrical nerve stimulation over the skin of the affected arm. This is a portable, safe and easy to use device designed for patients to operate in their homes.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 25 participants
Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Triple (Participant, Care Provider, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Optimizing Peripheral Stimulation Parameters to Modulate the Sensorimotor Cortex for Post-stroke Motor Recovery.
Actual Study Start Date : April 4, 2017
Estimated Primary Completion Date : December 1, 2020
Estimated Study Completion Date : December 1, 2020

Intervention Details:
  • Device: Somatosensory Electrical Stimulation
    We will put adhesive electrodes on the affected arm and connect it to a device that will deliver a gentle electrical stimulation to the hand and arm. The stimulation will last for different amounts of time, depending on the stimulation condition. This can be 30 minutes twice a day (1 hour apart), 1 hour continuously, 2 hours continuously, or 3 hours continuously. The stimulation conditions will also vary in stimulation strength. It is normal that some people may feel a tingling sensation, while others may feel nothing.
    Other Name: transcutaneous electrical nerve stimulation

Primary Outcome Measures :
  1. Change in Finger Fractionation [ Time Frame: Baseline and immediately post-stimulation ]
    Ability to fractionate movement can be assessed by asking the patient to move one segment in isolation and keep other, adjacent segments still.

Secondary Outcome Measures :
  1. Change in Modified Ashworth Scale [ Time Frame: Baseline and immediately post-stimulation ]
    standard instrument

  2. Change in Arm Research Action Test [ Time Frame: Baseline and immediately post-stimulation ]
    standard instrument
