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).
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.

| Mirror training | Other | Training will be performed one-on-one by an investigator in a quiet room, one hour a day, five days a week, for four weeks. The mirror-box apparatus consists of an 18" x 24" vertical mirror secured in the center of a wooden platform. During training, the mirror-box will be placed on a table in front of the subject so that the mirror is perpendicular to the chest, slightly lateral of midline. Subjects will be asked to attend to the mirror reflection of their unaffected hand performing a series of tasks, while keeping their affected limb still. At the end of the four week training period, posttests will be administered by the same therapist who performed the pretests. |

| The Fugl-Meyer Assessment of Motor Function After Stroke | The Fugl-Meyer Assessment of Motor Function After Stroke, a widely used scale of motor recovery after stroke. The subscale upper extremity motor function was used. This test requires progressively more complex movements and hand grasps and measure speed and coordination. Each item is graded on a 3-point ordinal scale (0=cannot perform; 1=partially performs; 2=performs fully) with a minimum score of 0 and a maximum score of 66 for the upper extremity. Higher scores indicate better outcome. | preintervention and post intervention |

| Arm Motor Ability Test | The Arm Motor Ability Test evaluates disabilities in upper extremity function in activities of daily living using a quantitative and qualitative measure. The Functional Ability Scale and the Quality of Movement Scale are rated on an ordinal scale from 0-5. The score for the Functional Ability Scale ranges from 0 to 140. The score for the Quality of Movement Scale ranges from 0 to 140. Higher scores on the Functional Ability and Quality Scale of the Arm Motor Ability Test indicate more normal movement and a better outcome. |
