Trial Outcomes & Findings for Sensory Stimulation to Enhance Hand Function Post Stroke (NCT NCT02675764)

NCT ID: NCT02675764

Last Updated: 2024-03-27

Results Overview

Change in hand motor function as measured by the Box and Block Test. This test measures the number of blocks that a participant moved in a minute. The scale ranges from 0 to a positive number. Higher numbers represent better outcomes.

Measure
Experimental (Therapy + Stimulation)
The experimental group receives the wrist subthreshold vibrotactile stimulation during therapy. Vibration: peripheral vibration at the wrist skin at an imperceptible level therapy: standardized hand therapy program
Placebo (Therapy + Stimulation Placebo)
The control group wears the vibration device with no vibration during therapy. Placebo (for vibration): No peripheral vibration at the wrist skin therapy: standardized hand therapy program

Measure
Experimental
n=6 Participants
The experimental group receives the wrist subthreshold vibrotactile stimulation during therapy. Vibration: peripheral vibration at the wrist skin at an imperceptible level therapy: standardized hand therapy program
Placebo
n=6 Participants
The control group will wear the vibration device with no vibration. * Both groups cannot feel the vibration since the vibration intensity is set below the perceptible level. * The vibration device is a generic, commercially-available, vibrator, not particularly used for this peripheral skin stimulation purpose. Placebo (for vibration): No peripheral vibration at the wrist skin therapy: standardized hand therapy program
