Dr. Joe Hidler, CEO of Aretech and inventor of the ZeroG Gait and Balance Training System discusses the research he and colleagues have done which has served as the catalyst as to why ZeroG was developed. This podcast was hosted by the Northern New Jersey Spinal Injury System with support from the National Institute on disability and Rehabilitation Research. US Department of Education grant H133N110020.
Dr. Hidler explains that one of his favorite quotes in relation to motor learning comes from John Krakauer, M.A., M.D., “Rehabilitation needs to emphasis techniques that promote the formation of an appropriate internal model and not just the repetition of movements.” Dr. Hidler describes how movements occur using internal model formations which start at birth and continue into adulthood. How does this work in stroke patients who have been using their internal models their entire life which now no longer are appropriate? Everything changes so now there is inefficient motor control.
Error signals are very important in the learning process. The variability of tasks and the task variability in the acquisition phase is very important and improves performance in subsequent sessions in the generalizing of learning new tasks. The ZeroG Gait and Balance Training System differs from other robotic rehabilitation systems which move the limbs for the patient. ZeroG builds on the basics of motor learning and motor control strategies to help progress patients while learning variability of tasks.
