Sommario breve
This project will develop a wearable rehabilitation robot suitable for in-bed acute stage rehabilitation. It involves robot-guided motor relearning, passive and active motor-sensory rehabilitation early in the acute stage post-stroke including patients who are paralyzed with no motor output. The early acute stroke rehabilitation device will be evaluated in this clinical trial.
Descrizione dettagliata
Stroke survivors often experience loss of motor control and impaired function. Immediately after stroke, there is a time-limited window of heightened plasticity during which the greatest gains in recovery occur. Therefore, early intensive sensorimotor rehabilitation post-stroke is critical in improving functional outcomes and minimizing disability. However, acute stroke survivors often receive little active training to improve mobility during their hospital stay and they are left alone during most of the day. Especially for those acute patients with no voluntary motor output, active motor training might be even less, partly due to a lack of rehabilitation protocols to detect potential motor recovering signals sensitively and facilitate neuroplastic changes. To address this unmet clinical need, this project will develop a novel wearable rehabilitation robot suitable for in-bed acute stage rehabilitation with guided motor relearning, passive and active motor-sensory rehabilitation early in the acute stage post-stroke including patients who are paralyzed with no motor output. The early acute stroke rehabilitation device will be evaluated in this clinical trial.

The Berg balance scale ranges from 0 to 56. It is a 14-item list with each item consisting of a five-point ordinal scale ranging from 0 to 4, with 0 indicating the lowest level of function and 4 the highest level of function. | At the beginning and end of 3-week training, and 1 month after the treatment ends |
10-meter Walk Test | The 10 Meter Walk Test is a performance measure used to assess walking speed in meters per second over a short distance at the beginning and end of 3-week training, and 1 month after the treatment ends.
