HealthWACH: Stroke rehab
Tue, 24 Sep 2013 02:00:00 GMT —
COLUMBIA (WACH)A stroke or â??brain attackâ?? occurs when a blood clot blocks an artery or a blood vessel breaks, disrupting blood flow to an area of the brain. When either of these things happens, brain cells begin to die and brain damage occurs. Whenever brain cells die during a stroke, abilities controlled by that area of the brain are lost. These abilities include speech, movement, and memory. People love their smartphones, but many of us take for grant the technology that is packed into our phones and tablets. Researchers at The Ohio State University Wexner Medical Center are inspired by it. They are the first to test the innovative approach that combines blue tooth technology with a computer program that charts the movement of a patientâ??s arms and legs during rehabilitation. â??These moving body parts are in a constant state of motion, but with this technology we can figure out how they are all working together. This gives us the ability to objectively, precisely, figure out at the bedside or in a rehab facility, how well someone is improving,â?? Stephen Page, PhD, FAHA, an occupational therapist at The Ohio State University Medical Center, was quoted as saying. Six sensors are placed on the participantsâ?? arms, legs, and chest. As the person walks the sensors relate information to each other and back to a computer that charts how and where the person is moving.Researchers are using this new technology to evaluate progress in a study that is combining electrical muscle stimulation, which has been used to improve muscle function for decades, with active motion on a recumbent bicycle. The goal of the study is to determine whether the combination of active motion and electrical stimulation provides added benefit for the patient through neuroplasticity, or retraining the brain. The first part of the study will examine ten people. Over the course of ten weeks, half of the participants will get the electrical stimulation on their legs while biking, and the other half will get a placebo.
Dr. Stephen Page says that close to 80 percent of stroke survivors have difficulties with arm movement. Most therapists have assumed for many years that there was only a small window of opportunity to rehabilitate arms that were damaged by a stroke. They would focus on the arms in the early stages of rehab. Dr. Page launched a new study to help change this notion. The study uses a hi-tech elbow brace known as â??bionic arm.â?? â??All of our muscles have whatâ??s called EMG or electromyography. It is essentially a signal that our muscle sends out when itâ??s moving, or attempting to move,â?? he said. â??When the patients attempt to move, even if itâ??s slow, or not even visible, this device will magnify those attempts to move and the robot inside will kick in and help them to move the rest of the way,â?? Dr. Page was quoted as saying. Researchers believe that the brain can actually be retrained to move the arm on its own, regardless of how long ago a patient had a stroke. They think the repetitive use of the â??bionic armâ?? will rewire the patientsâ?? brains.
