Mirror-Box Training in Adults With Chronic Hemiparesis Secondary to Stroke

Terminated

Phase N/A Results N/A

Trial Description

The purpose of this project is to assess the effects of four weeks of mirror-box training on weakness of one arm secondary to stroke. Primary measures are function and strength. Secondary measures will evaluate muscle tone, flexibility, and the subject's perception of their everyday function and improvement. Research Hypothesis: For chronic upper limb hemiparesis secondary to stroke, four weeks of mirror-box training with movement of the unaffected limb only results in a mean increase of 10 points on the Fugl-Meyer Test of Motor Recovery (Upper Extremity).

Detailed Description

Due to the relatively new nature of mirror training, there are few randomized controlled studies. This pilot case series will serve as our initial step in trying to identify the frequency, duration, and treatment exercises needed in this population. Additionally, this pilot will allow us to ensure our outcome measures are appropriate to detect meaningful treatment changes. After obtaining informed consent, 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.

Conditions

Interventions

  • Mirror Box Therapy Other
    Intervention Desc: 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.
  • Motor Training Other
    Intervention Desc: Mirror training and motor imagery

Trial Design

  • Allocation: Non-Randomized
  • Masking: Open Label
  • Purpose: Treatment
  • Intervention: Single Group Assignment

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.
