Effectiveness and Safety of Electrically Powered Orthopedic Exercise Device for Gait Disorders

In the researchers' words

Aging is a global trend, and consequently, the prevalence of age-related diseases is increasing. Gait disorders are common among the elderly and can result not only from various underlying conditions affecting gait but also from the decline in physiological and neurological functions associated with the normal aging process. Gait is a fundamental daily activity that requires the coordinated integration of the central and peripheral nervous systems, as well as the musculoskeletal system. Therefore, impairments in any of these systems-including the nervous, cardiovascular, respiratory, or musculoskeletal systems-can lead to gait dysfunction. Gait disorders negatively impact quality of life by increasing the risk of falls, reducing the ability to perform activities of daily living (ADLs), and limiting physical activity. Accordingly, various approaches to maintaining and improving gait function in older adults are being actively explored. Currently, gait aids such as canes and walkers are commonly used to support individuals with gait impairments. These devices help redistribute body weight by providing a broader base of support, thereby assisting with balance and stability. However, they do not directly facilitate the movement of the lower limbs. To enhance gait function, numerous studies have investigated repetitive lower-limb movement training using bicycles or robotic…
