Control Strategies for Robot Therapy

Abstract

The patients hit by stroke have primary concerns of upper and lower limb weakness. To recover from these disorders patients, undergo a process known as rehabilitation. Robotic devices have the potential to address this area as noted by the previous studies. The purpose of this technology is build such devices which serves individuals motor impairments to practice the movement without the supervision of therapist. Formerly several devices were developed but such resources are limited. Studying and improving the devices used in therapy maximises the potential of restoration and provides greater means of access to cost effective healthcare devices. Control strategies play a substantial role in the success of these type of robotic devices. The purpose of this study is to document a review of control strategies which have been implemented previously on the rehabilitation robotic devices assisting either upper or lower limb in order to facilitate the development of new and improved strategies.
