Efficacy of rehabilitation robotics for walking training in neurological disorders: A review

Abstract

Abstract-Robot-assisted treadmill training is an established intervention used to improve walking ability in patients with neurological disorders. Although it has been shown that attention to the task is a key factor for successful rehabilitation, the psychological state of patients during robot-assisted gait therapy is often neglected. We presented 17 nondisabled subjects and 10 patients with neurological disorders a virtual-reality task with varying difficulty levels to induce feelings of being bored, excited, and overstressed. We developed an approach to automatically estimate and classify a patient's psychological state, i.e., his or her mental engagement, in real time during gait training. We used psychophysiological measurements to obtain an objective measure of the current psychological state. Automatic classification was performed by a neural network. We found that heart rate, skin conductance responses, and skin temperature can be used as markers for psychological states in the presence of physical effort induced by walking. The classifier achieved a classification error of 1.4% for nondisabled subjects and 2.1% for patients with neurological disorders. Using our new method, we processed the psychological state data in real time. Our method is a first step toward real-time auto-adaptive gait training with potential to improve rehabilitation results by optimally challenging patients at all times during exercise.

New Trends In Rehabilitation Of Patients With Multiple Sclerosis

“…Taka forma rehabilitacji jest szczególnie przydatna u chorych ze znacznym zaburzeniem funkcji chodu. Technika ta ma na celu odtworzenie fizjologicznego wzorca chodu z zachowaniem optymalnych kinematycznych i czasowych parametrów [16][17][18].…”

The road ahead for rehabilitation robotics

“…In this single-topic issue dedicated to rehabilitation robotics, we have assembled an outstanding collection of articles that introduce, review, and study various upper-and lower-limb robotic technologies. Tefertiller et al provide a much-welcome clinical perspective with a comprehensive review of the evidence to date for the efficacy of robotic devices for lowerlimb therapy [6]. The latest in overground gait training systems is represented in this issue with an article on ZeroG [1].…”
