Official Title: | Task-Specific Upper-Extremity Robotic Training for Stroke Neurorehabilitation |

Arm | Intervention/treatment |
---|---|
Experimental: Robotic
The experimental group will receive 1-hour robotic training sessions, 3 times per week for a total of 12 sessions supervised by a research assistant. Immediately following this robot training, these subjects will receive the same dosage and schedule (1-hour sessions, 3 times/week, 12 total sessions) of conventional one-on-one therapy from an occupational therapist.
|
Device: Robotic Therapy
Subjects will be placed in the robot and practice common upper extremity tasks involving grasping, manipulating and moving objects.
Other: Conventional Therapy
An occupational therapist will provide one-on-one individualized programs focused on arm function. Treatment will focus on practice of specific tasks, such as reach, grasp, transport and release of various objects between different targets. Progression is done by varying the shape, size and weight of objects, altering the end range of the target or increasing the speed of movement.
|
Active Comparator: Conventional
Subjects will receive 24 hours of one-on-one treatment from an occupational therapist. The treatment schedule will parallel that given to the experimental group (1-hour sessions, 3 times/week).

- Change in Fugl-Meyer score [ Time Frame: Change from baseline to 8 weeks ]The Fugl-Meyer Test of Motor Function will be used to assess motor impairments at the shoulder, elbow, wrist and fingers. The Fugl-Meyer test scores reflexes and the ability to perform several movements and tasks on a 3-point scale. The Fugl-Meyer was designed for the recovery patterns observed after stroke and is very responsive to change in severe and moderately impaired subjects.
- Change in Action Research Arm Test [ Time Frame: Change from baseline to 8 weeks ]The Action Research Arm Test (ARAT) is an impairment level measurement tool that assesses the functional limitations of the upper extremities. It is one of the most frequently used primary endpoints in upper extremity (UE) training trials in stroke. The assessment incorporates 19 items that are divided into four subscales: Grasp, Grip, Pinch, and Gross movement. Item scores are summed to form a subtest score, and then a full-scale score.
- Change in Motor Activity Log [ Time Frame: Change from baseline to 8 weeks ]The Motor Activity Log (MAL) will be used to assess use of the limb at home. It is a structured interview during which respondents are asked to rate how they use their more-impaired arm for 28 activities of daily living (ADL) in the home over a specified period. Activities include brushing teeth, buttoning a shirt or blouse, and eating with a fork or spoon.
- Change in Fugl-Meyer score at follow-up [ Time Frame: Change from baseline to 8 months ]The Fugl-Meyer Test of Motor Function will be used to assess motor impairments at the shoulder, elbow, wrist and fingers. The Fugl-Meyer test scores reflexes and the ability to perform several movements and tasks on a 3-point scale. The Fugl-Meyer was designed for the recovery patterns observed after stroke and is very responsive to change in severe and moderately impaired subjects.
