Effectiveness and Safety of the Electrically Powered Orthopedic Exercise Device on Gait Ability in Patients With Hip Joint Diseases
Sponsor: Yonsei University
Summary
Gait is an essential daily activity performed through the complex coordination of the central and peripheral nervous systems and the musculoskeletal system. Gait disorders can negatively affect quality of life, increase the risk of falls, decrease the ability to perform daily activities, and limit physical activity. Various musculoskeletal diseases can cause gait impairment, with hip osteoarthritis and osteonecrosis of the femoral head (ONFH) being the most representative conditions. Various interventions can be attempted during the early stages of hip joint disease progression. However, improvement in symptoms does not necessarily indicate a halt in disease progression. As the condition advances in most patients, thinning of the full-thickness hip cartilage or collapse of the femoral head occurs, leading to restricted hip range of motion, weakness of the lower limb muscles and functional deterioration, resulting in the need for total hip arthroplasty. THA offers significant improvements in pain relief and function, regardless of the patient's preoperative status, and can reduce long-term healthcare costs. However, performing THA at an early stage with minimal functional improvement is not recommended. Postoperative complications, such as infections, aseptic loosening, and instability, are potential risks, with younger patients aged 45-64 showing higher revision surgery rates compared to those aged 65 and older. This highlights the need for new interventions that can delay the time to surgery while improving gait function and muscle strength. Therefore, this study aims to explore the clinical feasibility of the Angel Suit H10 (Angelrobotics, Seoul, Korea) by assessing whether wearing the Electrically Powered Orthopedic Exercise Device improves gait function in patients with hip joint diseases, along with evaluating user satisfaction and device safety.

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.
