Portable EMG-triggered Hand Robot for Individuals After Stroke

Trial Description

This is an interventional pilot study investigating the feasibility of using the hand of hope (HOH) device for individuals with decreased hand function after stroke.

Detailed Description

The HOH will be used to provide hand training for patients with decreased hand ability after stroke. The HOH is a light-weight, non-invasive, portable hand robot that provides physical assistance when a patient activates the muscles that open and close the hand. The HOH works by detecting surface EMG muscle activity and therefore requires active participation from the patient throughout the session. Video games linked to the HOH device are specifically designed to work on opening and closing the hand facilitating mass practice and high repetition needed for improving strength and range of motion of muscles.

Conditions

Interventions

  • Hand of Hope (HOH) Device
    Intervention Desc: Subjects will receive arm training 3x/week for 6 weeks, each session is anticipated to last approximately 60 minutes. Sessions will be scheduled for Monday, Wednesday, and Friday whenever possible to provide a rest period between sessions. Each session will consist of the following: warm up-passive stretch of hand in flexion and extension (5 minutes); setting the EMG threshold parameters for the device; active practicing of opening the hand (Desperate Bee, Hungry Bird, Sun Archer games; 10 min) active practice of closing then hand (UFO Catcher game; 10 min) open and closing the hand (Ball and Basket game; 10 min) open and closing the hand while incorporating reach ( for subjects with adequate ability to reach with shoulder/elbow; 10 min) cool down-passive stretch of hand in flexion and extension (5 minutes)
    ARM 1: Kind: Experimental
    Label: interventional group
    Description: This is a single group, interventional pilot study. All participants will receive 6-week hand training on the HOH device.
