Abstract

Background: The main key to the 4th industrial era is robots, and wearable robots are incorporated into human healthcare. Samsung Electronics' Bot Fit is a hip joint-centered assistive robot that can induce walking posture and energetic walking exercises.

Methods: This study is a cross-section study. Fifty-eight subjects consisting of older and younger adults participated. The straight walking test was conducted under the conditions of bare body, wearing the wearable robot Bot Fit assist mode, and applying voice coach. Spatio-temporal gait parameters were analyzed and the statistical significance level was set at 0.05.

Results: When assist mode and voice coach were applied, pelvic movement in 3 axes, stride length, and walking speed compared to the bare body increased. In young adults, stride length difference decreased in assist mode 1 and voice coach 1 compared to the bare body.

Conclusion: Bot Fit's assist mode and voice coach method positively influence walking efficiency, posture, stride length, and speed, though potential interaction effects between these interventions should be considered. Personalized, real-time adjustments show promise for optimizing walking exercises, warranting further investigation into their long-term and population-specific effects.

期刊介绍： BMC Musculoskeletal Disorders is an open access, peer-reviewed journal that considers articles on all aspects of the prevention, diagnosis and management of musculoskeletal disorders, as well as related molecular genetics, pathophysiology, and epidemiology. The scope of the Journal covers research into rheumatic diseases where the primary focus relates specifically to a component(s) of the musculoskeletal system.
