Brief summary
The purpose of the study is to determine whether an existing treatment for problems that participants have with making movements after a stroke can be performed at home.
Detailed description
This study will compare two forms of home-based treatment for post-stroke problems making movements with the arms and hands. After initial pre-treatment assessments, participants will complete 4 weeks of treatment, with assessments after each week of treatment and 3 months after the completion of treatment.
Interventions
A home-based therapy involving mirrored visual feedback
A home-based therapy involving removed visual feedback.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Upper Extremity Fugl-Meyer | Immediately after 1 month of treatment | This test measures impairment-level ability to move the arm and hand. Scores range from 0 to 66, with higher scores indicating greater ability to move the arm and hand. |
| Action Research Arm Test | 1 month | The test measures the ability to complete simulated everyday tasks with the arm. Scores range from 0 to 54, with higher scores indicating better performance. |
| Rivermead Assessment of Somatosensory Performance | 1 month | This test measures the integrity of sensory perception of the arm. The score is the proportion of items answered correctly, and ranges from 0 to 1 with higher scores indicating better performance. |
| Virtual-reality Assessment of Navigation | 1 month | This test measures the ability to detect lateralized attention problems in a simulated navigation test. Evidence for lateralized attentional problems was defined as a 20% difference in item detection between the left and right side. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Stroke Impact Scale | 1 month | This test measures the self-reported ability to complete everyday tasks with the arm. Total scores for all items are reported. The scale ranged from 0 to 300, with higher scores indicating higher self-reported ability. |
| Wolf Motor Function Test | 1 months | The test measures the ability to completed simulated everyday tasks with the arm. The scale ranged from 0 to 75, with higher scores indicating better performance. |
