Robotics Lab Helps Stroke Patients with Recovery From: Rice University Press Release - 11/29/2007 By: Jade Boyd Robotics engineers at Rice University will work with a local rehabilitation hospital over the next two years to study the effectiveness of a PC-based system in assisting stroke patients with their recovery. Experts at Rice's Mechatronics and Haptic Interfaces Laboratory (MAHI) developed the prototype rehabilitation system, which uses force-feedback technology to enable patients to "feel" their environment in virtual reality. Patients can use the joystick to move objects on a computer screen in a smooth and precise manner, and their hands will be guided by the stick's ability to resist movements in the wrong direction. "The computer can precisely measure how a patient responds to every single exercise," says Marcia O'Malley, an assistant professor of mechanical engineering and materials science who also serves as the director of MAHI. "We hope to refine our system to allow patients to recover faster and to allow therapists to more precisely monitor patients' recovery." Cost will no longer limit the use of computer-controlled robots to small-scale physical rehabilitation efforts in a few years, O'Malley says. Also, patients have embraced the technology.

But robotics engineers at Rice University hope to speed the recovery process by developing a joystick system to help patients improve eye-to-hand coordination. The research effort, led by Rice's director of the Mechatronics and Haptic Interfaces Laboratory, Marcia O'Malley, uses the concept of force feedback technology - called "haptics" - to enable people to "feel" their environment while in virtual reality. Haptic refers to the perception of touch, and in the prototype rehab system, the joystick has motors that push the stick-to-resist moves in the wrong direction. As a result, the patient's hands are guided along the right path. Repetition of the exercise enables the patient to precisely control objects on a PC screen. O'Malley noted that while researchers have used computer-controlled robots for physical rehabilitation since the early 1990s, the technology has been too costly to use on a large scale. She expects this will change over the next few years as more patients embrace the technology. Read the entire article at: http://www.media.rice.edu/media/NewsBot.asp?MODE=VIEW&ID=10323&SnID=2319883
