Efficiency of Leg Exoskeleton Use in Rehabilitation of Cerebral Stroke Patients

Abstract

Abstract The study aimed to evaluate the effectiveness of functional and motor activity restoration, including the walking function, in patients after an ischemic stroke using the ExoAtlet lower limb exoskeleton. Patients and methods. A clinical study was carried out on 42 patients who had undergone a cerebral infarction in the mid cerebral artery system with a post-stroke paresis of the leg, and who had undergone a rehabilitation course in a round-theclock hospital during the early recovery period. Patients were randomized into two equal groups comparable in terms of the stroke severity: the patients in group 1 were receiving a standard rehabilitation program (control group), the patients in group 2 were additionally receiving a course of gait rehabilitation using the ExoAtlet exoskeleton - 10 sessions, 5 sessions per week for 14 days. Results. The study demonstrated the effectiveness of the ExoAtlet exoskeleton used in the rehabilitation of stroke patients over the standard course of rehabilitation. The advantages include a decrease in the hemiparesis degree, an increase in the muscle strength of the paretic limb, an improvement in balance, an improvement and acceleration of the walking process. The obtained results of the instrumental study confirmed the benefits of physical training on the Exoskeleton, which was demonstrated through an increase in stability and balance, as well as through a decrease in the energy consumption index for maintaining the stable verticalization. Conclusion. The usage of the ExoAtlet exoskeleton increases the effectiveness of rehabilitation measures and improves motor and functional activities of patients who have suffered a cerebral stroke.
