Design and implementation of a low cost gait refrain ment device which helps in the mobility of the MS (multiple sclerosis) patients is discussed in this paper. Walking impairment is one of the most ubiquitous features of Multiple Sclerosis. There is an increasing trend in using robots for medical purposes especially in neuro rehabilitation. There are some commercial exercise machines used for such rehabilitation purposes. However, these machines have limited use because of their insufficient freedom of movement and lack of flexibility. This paper introduces an exoskeleton robot manipulator for gait assistance for Multiple Sclerosis patients. This exoskeleton is capable of supporting the bodyweight of the patient partially. It takes the EMG signals of the patient to generate the control signals and deliver it to the actuator. The exoskeleton proved to be of much help to the MS patients in walking as the patient with relapsing remitting Multiple Sclerosis disease can control it like their normal leg. © 2006-2013 Asian Research Publishing Network (ARPN).
