Cordo Lab Conducts Stroke Rehab Research

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, fingers, and the ankle that can be used by individuals who have had a stroke. The subject puts his/her 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 3-4 treatments per week for 30 minutes per treatment for the duration (30 treatments) of the participant’s participation in the study. 

Volunteers (ages 18-85) who have had a stroke at least one year 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 the study physician. Participation will depend on overall severity of stroke symptoms, how much sensation remains in the affected limb, and willingness to complete all study requirements. 

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 will have the opportunity to participate in the science of stroke recovery.
