Mirror-Box Training in Adults With Chronic Hemiparesis Secondary to Stroke
|
Status:
This study is ongoing, but not recruiting participants.
Purpose:
To assess the effects of four weeks of mirror-box training on weakness of one arm secondary to stroke.
Interventions:
Mirror Box Therapy
A mirror box is a box with two mirrors in the center (one facing each way). The patient places both extremities in the box and using visual cues from the functioning limb to improve function in the stroke affected limb.

Design:
Interventional, Treatment, Non-Randomized, Open Label, Uncontrolled, Single Group Assignment.
Inclusion Criteria
First unilateral ischemic stroke resulting in hemiparesis at least 6 months prior to enrollment; patient willing to comply with protocol and is available for all scheduled visits; residual upper extremity hemiparesis; no changes in medications planned during 8-week participation; no other motor rehabilitative therapy during 8-week participation, including E-stim and acupuncture; at least 20 degrees of active wrist extension and 10 degrees of active finger extension against gravity in the affected upper limb, as measured by goniometry.
Exclusion Criteria
Serious cognitive deficits, as evidenced by score of <20 on Modified Mini-Mental Status Exam; hemorrhagic or bilateral strokes; excessive spasticity at the elbow, wrist, or hand, defined as a Modified Ashworth Scale score of >2; history of botulinum toxin injection in affected upper extremity in the past 4 months; lacking >40 degrees of passive elbow extension; less than 45 degrees of passive shoulder flexion;
global or receptive aphasia present on physical exam; hemispatial neglect present on physical exam; patient participating in constraint-induced therapy during study time period; severe visual deficits or visual field deficits as determined by ability to ascertain number of fingers held up on visual field testing; deformity/amputation of unaffected upper limb.
Patient Involvement:
Patients will undergo two separate baseline assessments of strength, function, and tone 4 weeks apart. Training sessions will consist of supervised activities using the unaffected arm while observing its mirror reflection; the affected arm will remain still. Sessions will be one hour a day, five days a week, for four weeks. Patients will be tested for strength, function and tone in the affected arm at completion of the four week treatment period by the same occupational therapist that performed the pretests.
Primary Outcome:
Fugl-Meyer Test of Motor Recovery, Upper Extremity
Secondary Outcome:
Arm Motor Ability Test.
