Exoskeleton Device For Left Hemiplegia Patients With Electromyograph

Abstract

Abstract Loss of motion is a condition in which muscle activity in a part of the body is lost; it is also known as paralysis. Loss of motion is most commonly caused by a severe stroke, in which the blood supply to a portion of the cerebrum is cut off. Hemiplegia is a sort of loss of motion which influences half of the body, i.e., one arm and one leg of same side of the body will not be functioning. Normally, left hemiplegia is a severe disease caused by a lack of blood supply to the cerebrum’s right hemisphere. Fixed frameworks, such as Lokomat, are used in rehabilitation centres to assist patients in resuming their normal activities. However, the results provided by those frameworks are extremely time-consuming and will only benefit patients who can walk on a treadmill. However, these frameworks are not portable and cannot be used for home or day-to-day exercises. To overcome these disadvantages, this paper presents the ergonomic framework, which includes an exoskeleton that guides and assists in the development process of the left upper arm. The entire framework is powered by a compatible and miniaturized motor via a microcontroller, which aids in the development of patient flexion and augmentation. Meanwhile, EMG acquisition would be done by putting flexible pre-gelled electrodes to know the recuperation of physiological neuro-muscular activities of the subject.
