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.

Figure 3: Mean success rate (%) and response time (s) to stimuli for each trial in each game improved as sessions progressed: (A) ball game, (B) cave game, and (C) rhythm game. Error bars indicate standard error.

Mentions: Mean response time decreased significantly across sessions during the balloon game (B=-0.138, SE=0.030, p=0.002), cave game (B=-0.410, SE=0.120, p=0.011), and the rhythm game (B=-0.037, SE=0.009, p=0.003). The success rate for the balloon game increased significantly across training sessions (B=1.140, SE=0.145, p<0.001). A trend toward an increased success rate (B=0.083, SE=0.038, p=0.059) was observed during the cave game. Success rate increased significantly across sessions of the rhythm game (B=0.155, SE=0.213, p=0.001) (Fig. 3).
