Overview
Brief Summary
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.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Diagnosis of stroke \> 6 months ago
- •Presence of some active range of motion (AROM) in the affected hand, measured by a score of at least 1 on the Box and Block test.
- •Intact sensation in the affected hand
- •Full passive range of motion (PROM) in mass flexion and extension of the hand
- •MAS score \< 3 for finger flexors and intrinsics
- •MAS score \< 3 for finger extensors
- •Visual tracking is intact in all directions
- •Patient must be otherwise medically stable in the opinion of the principal investigator
Exclusion Criteria
- •Patient is receiving active occupational or physical therapy for the affected arm
- •Patient has joint contractures that prevent proper fit into the HOH device
- •Patient has other concurrent neurological or orthopedic diagnoses that affect motor ability of the arm such as Parkinson's or Multiple Sclerosis, or arthritis
- •It has been less than 3 months since last botulinum toxin injection in the affected arm
Outcomes
Primary Outcomes
Box and Blocks
Time Frame: Baseline to 6 weeks (discharge)
The Box and Blocks is a performance-based functional assessment of hand dexterity ( gross grasp and release). The total score is the number of 2.5cc blocks successfully transferred from one box to another with the affected hand in one minute.
Fugl-Meyer Assessment of Upper Extremity (FMA)
Time Frame: baseline to 6 weeks (discharge)
The FMA is a performance based evaluation of upper limb impairment of the affected arm after stroke. Scoring is based on an ordinal scale of 0 (no movement) to 2 (normal movement). Scoring is based on sum of 30 items, ranging from 0-60.
Arm Motor Ability Test (AMAT)
Time Frame: Baseline to 6 weeks (discharge)
The AMAT is performance based measure of functional ability of the affected arm and hand in unilateral and bilateral everyday tasks. It is comprised of 10 functional tasks such as cutting meat with a knife and fork, donning a t-shirt, and phone use with a score ranging from 0 to a maximum of 5 for each item. The total score is the mean score for all individual item scores.
Secondary Outcomes
- Stroke Impact Scale --Hand Sub Scale (SIS-H)(baseline to 6 weeks (discharge))
- Stroke Upper Limb Capacity Scale (SULCS)(Baseline to 6 weeks (discharge))
- Hand Dynamometry(baseline to 6 weeks (discharge))
