ABSTRACT

Objective: To improve lower extremity function and balance in elderly persons, we developed a novel, three-dimensional interactive augmented reality system (3D ARS). In this feasibility study, we assessed clinical and kinematic improvements, user participation, and the side effects of our system.

Methods: Eighteen participants (age, 56-76 years) capable of walking independently and standing on one leg were recruited. The participants received 3D ARS training during 10 sessions (30-minute duration each) for 4 weeks. Berg Balance Scale (BBS) and the Timed Up and Go (TUG) scores were obtained before and after the exercises. Outcome performance variables, including response time and success rate, and kinematic variables, such as hip and knee joint angle, were evaluated after each session.

Results: Participants exhibited significant clinical improvements in lower extremity balance and mobility following the intervention, as shown by improved BBS and TUG scores (p<0.001). Consistent kinematic improvements in the maximum joint angles of the hip and knee were observed across sessions. Outcome performance variables, such as success rate and response time, improved gradually across sessions, for each exercise. The level of participant interest also increased across sessions (p<0.001). All participants completed the program without experiencing any adverse effects.

Conclusion: Substantial clinical and kinematic improvements were observed after applying a novel 3D ARS training program, suggesting that this system can enhance lower extremity function and facilitate assessments of lower extremity kinematic capacity.

The angle of each joint (curved arrow) was calculated based on joint position using the 3D kinetic sensor. (A) External hip rotation angle, (B) internal hip rotation angle (angle of a vector from the knee to the ankle, with a vertical reference vector in the coronal plane), (C) hip extension and flexion angle, and (D) knee flexion angle (angle of a vector from the hip to the knee, with a vertical reference vector in the sagittal plane).

Mentions: Several movement parameters for the joint of interest in each game were also recorded during the exercises: the angle of hip flexion and external and internal hip rotation during the balloon game, and the knee flexion angle in the cave and rhythm games (Fig. 2).
