Cordo Lab Conducts Stroke Rehab Research

Preliminary findings from the laboratory of Paul Cordo, Ph.D., indicate that individuals who have experienced a stroke, and whose muscle weakness has stabilized can benefit from a three-part approach to rehabilitation. In addition to range-of-motion and exercise, patients receive sensory stimulation. Dr. Cordo has developed computerized exercise machines for the wrist (and fingers) and the ankle that are placed in the homes of the subjects. The subject puts his arm or leg into a sleeve or boot that delivers vibration to the limb. The vibration stimulates sensory pathways, which, it is hoped, will invigorate the motor pathways in the brain that control movement. The subject is expected to exercise with the device for 30 minutes per day, every day.  Periodically during the 6-month duration of the test a technician will visit the home to download data from the computer. 

Volunteers (ages 18-85) who have had a stroke at least six months ago and are otherwise in good health will be considered for this study. As a prerequisite for consideration, all potential subjects must first be examined by an Oregon Stroke Center physician involved in the study. Participation will depend on overall severity of stroke symptoms, willingness to exercise every day, and how much sensation remains in the affected limb.

While this study might provide clues regarding a person’s ability to repair the injury caused by a stroke and, thereby, improve function, this experiment is designed to test the merit of this rehabilitation approach. By participating in the study, a stroke patient and his/her family caregiver will have the opportunity to participate in the science of stroke recovery. If you or a loved one or friend feel that you might be interested, please feel free to contact Linda Cordo at 503-494-8773.
