밸런스 보드 (Balance Board, BB)를 활용한 운동은 균형 감각 발달, 코어 근육 강화 등 신체 운동 능력 향상과 집중력 증진에 효과적이다. 특히, 다양한 디지털 콘텐츠와 연동되는 스마트 밸런스 보드 (Smart Balance Board, SBB)는 기존 밸런스 보드에 비해 적절한 피드백을 제공하여 운동 효과를 극대화한다. 그러나 대부분의 시스템들은 시/청각적인 피드백만 제공하여 사용자의 운동 몰입도 및 흥미 그리고 운동 자세의 정확성에 미치는 영향을 평가하지 못한다. 본 연구에서는 멀티 센서를 활용하여 다양한 피드백과 정확한 자세로 훈련이 가능한 몰입형 스마트 밸런스 보드 (Imemersive-SBB, I-SBB)를 제안한다. 제안된 시스템은 아두이노 기반으로 보드의 자세을 측정하는 자이로 센서, 유/무선 통신을 위한 통신 모듈, 사용자의 정확한 발 위치를 유도하는 적외선 센서, 촉각 피드백을 위한 진동 모터로 구성되어 있다. 측정된 보드의 자세는 칼만 필터 (Kalman Filter)를 이용하여 부드럽게 보정되고, 멀티 센서 데이터는 FreeRTOS를 활용해 실시간으로 병렬처리된다. 제안된 I-SBB는 다양한 콘텐츠와 연동하여 사용자의 집중도 및 몰입도 향상과 흥미 유발에 효과적임을 보인다.

The purpose of this study was to investigate whether there were improvements on balance when both ankle-jointed calf muscles and hip muscles, which affect balance capabilities, were activated through taping techniques and EMS. In this study, the One Leg Standing Test, a static balance test, was conducted by experimenting on a flat floor, foam pad, and a stretching board with a gradient of 20 degrees, respectively, to study static balance capabilities in different situations. Nine healthy men in their 20s were measured five times every five minutes considering muscle fatigue, and the difference between each variable was analyzed through post-test using nonparametric statistical analysis. Our results showed an equal increase in static balance capability was similar when EMS was applied only to calf muscles and only to hip muscles. Notably most improvements were seen when wearing calf supporters and taping technology pants, and applying EMS together. It was also found that the difference between EMS electric stimulation and balance capability was greater when wearing and applying supporters and taping technology pants. Based on the results of the present study, a muscle support band and EMS of taping techniques can improve balance capabilities. These findings are expected to form a basis for solutions Improving the balance capabilities

The purpose of this study was to effectively improve the thigh muscles of adult women working from home due to COVID-19. In this study, ten adult women working from home performed 1) an electromyography test, 2) a static balance test on a balance board, and a 3) dynamic balance test by squatting on a Bosu ball four times: before electric muscle stimulation (EMS), after EMS, after high-intensity circuit training (HICT), and after EMS plus HICT. For this test, EMS was attached to a medical knee support to manufacture an EMS knee band that could be easily worn regardless of the location. For the experiment, EMS(electric muscle stimulation) was attached to the medical knee protector to manufacture an EMS knee band that can be easily worn regardless of location, and was measured based on the right foot. The study results confirmed that in all tests (electromyography test, static balance test on the balance board, and dynamic balance test by squatting on a Bosu ball), thigh strength improved in the order of treatment before EMS, after EMS, after HICT, and after EMS plus HICT. The study showed that people working from home or with activity restrictions due to COVID-19 had better exercise effects when wearing the EMS knee band and performing HICT, even in a small space.
