What is your doctor doing CURRENTLY to get your hand back? Or will this maybe BE AVAILABLE for your children and grandchildren?
Kessler Foundation participates in new study to test innovative treatment for hand paralysis
Kessler Foundation is participating in a phase II multi-site study of
an innovative treatment to improve hand function in stroke survivors.
Olga Boukrina, PhD, research scientist in the Center for Stroke
Rehabilitation Research, is the site's principal investigator. The study
is funded through a five-year $3.2 million grant from the National
Institutes of Health awarded to the principal investigator, Jayme S.
Knutson, PhD, director of Research and associate professor of Physical
Medicine and Rehabilitation at the MetroHealth System and Case Western
Reserve University.
This is the first multi-site clinical trial of contralaterally controlled functional electrical stimulation (CCFES), a new rehabilitation intervention for hand recovery following stroke developed by Knutson and colleagues. With CCFES, electrical stimulation is applied to the muscles of the weak hand through surface electrodes, causing the weak hand to open, a function that is often lost in stroke survivors. The patient controls the stimulation to their weak hand through a glove with sensors worn on their opposite, unaffected hand. Opening their unaffected hand delivers a proportional intensity of electrical stimulation that opens their weak hand, and enables them to practice using their hand in therapy. Researchers will enroll 129 patients who are 6 to 24 months post stroke who have upper extremity hemiparesis and limited hand movement.
The effectiveness of CCFES will be compared with two other treatments -- cyclic neuromuscular electrical stimulation (CNMES), which has pre-set duration and intensity of stimulation and operates independent of patient control, and traditional task-based training without stimulation. Participants will be randomly assigned to one of the three treatment options for 12 weeks. The research teams will administer the treatments and conduct blinded outcome assessments. The durability of functional improvements will be evaluated at 6-month follow-up. Study sites include the MetroHealth System (Jayme Knutson, PhD), the Cleveland Clinic (Ela Plow, PT, PhD), Emory University (A.M. Barrett, MD), and Johns Hopkins University (Preeti Raghavan, MD).

Because hand function is integral to so many activities of daily living, advances that improve function can have significant effect on the lives of stroke survivors. This study will help determine the optimal method for restoring hand function. We anticipate that putting the patients in control of stimulating their weak hand with CCFES may activate neuroplastic changes that lead to greater and longer lasting functional gains."
