Effectiveness and Safety of Electrically Powered Orthopedic Exercise Device for Gait Disorders
Sponsor: Yonsei University
Summary
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 devices. However, the extent of functional improvement resulting from such training remains unclear, and the long-term efficacy is still uncertain. Recent advancements in sensing technology for joint motion and actuator efficiency have led to the development of wearable assistive devices that are significantly more compact and lightweight compared to conventional robotic systems. This study aims to evaluate the effectiveness of a newly developed electrically powered orthopedic exercise device in patients with gait disorders by assessing changes in gait parameters upon wearing the device, thereby exploring its clinical feasibility.

Electrically Powered Orthopedic Exercise Device
Participants who pass the screening undergo an evaluation of gait function and balance ability without wearing the Electrically Powered Orthopedic Exercise Device. Afterward, the patient wears the motorized orthopedic exercise device for a total of four adaptation sessions. In each session, the patient performs short-distance walking within 10 meters while wearing the device to explore the appropriate assistive mode and level of support that match their physical condition. No evaluations are conducted while wearing the device during sessions 1, 2, and 3. After the 4th session, an evaluation identical to the one conducted without the device is performed while wearing it, and a satisfaction survey is conducted.
