Effectiveness of Adding Robotic Therapy to Conventional Therapy for Acute Stroke Patients With Upper Extremity Paresis
The purpose of this study is to compare standard occupational therapy to a combination of
conventional (standard) and robotic therapy. The Reo Go device will provide robotic therapy
that gives therapists a tool that could make stroke treatment faster and better by helping
patients practice more accurate arm movements with help from the device.

HYPOTHESES
- Motor function will be significantly greater for the patients in the robotic training
group as measured by standard clinical evaluations.
- Functional independence gains will be similar for both groups because the robotic
therapy is not task-specific for activities of daily living (ADL).
- Robotic training will reduce pain and spasticity more effectively than conventional
therapy alone, due to increased number of movements performed during the robotic
training.
- Muscle activation patterns for patients receiving robotic training will show decreased
agonist/antagonist co-contraction and less erratic muscle activation.
- Robotic training patients will demonstrate significantly greater ROM, movement accuracy
and higher movement speed during exercises performed as part of robotic training. For
robotic exercises performed only as part of the robotic assessment, these improvements
will be significantly less than those for practiced movements.

Inclusion criteria Right hemisphere, unilateral ischemic stroke with onset of less than 15
days that results in arm weakness Right-handed 65-84 years of age Manual Muscle Test score
of at least 2/5 Must be able to follow 2-3 step commands Head, neck, and trunk control to
maintain an upright posture for a minimum of 45 minutes Some synergistic movement at
shoulder Active shoulder flexion and/or abduction greater then 30 degrees Active elbow
flexion of 45 degrees or more
Exclusion criteria
- Previous stroke history
- Hemorrhagic stroke, cerebellar stroke, or subarachnoid hemorrhage
- Contractures in the involved upper extremity at the shoulder, elbow, or wrist
- Moderate to severe tone in the involved upper extremity
- Flaccid involved upper extremity
- Full, active isolated movement of the involved upper extremity
- Corrected visual acuity worse than 20/50 for distance
- Cognitive or other deficits that would negatively affect their ability to follow
directions or track visual targets
- Unstable cardiovascular orthopedic or neurological conditions that would preclude
exercise in short-duration, high work-load trials
