본 연구에서는 전기 근육 자극(electrical muscle stimulation, EMS)에 사용되는 기존의 하이드로겔 패드의 단점인 사용 편의성, 쾌적성 등을 보완할 수 있는 e-textile (electronic textile)을 이용한 전기 근육 자극(electrical muscle stimulation, EMS) 패드인 EMSCT (electrical muscle stimulation conductive textile)를 연구를 하고자 하였다. SWCNT (Single-Walled Carbon Nanotube)와 H₂O의 농도 및 함침 공정 횟수를 변수로 하여, EMSCT는 5가지 직물(라디론, 네오프렌, 스판쿠션, 폴리100%, 베르가모)에 전도성을 부여하여 실험이 진행되었다. SWCNT (Single-Walled Carbon Nanotube)와 H₂O을 이용한 패딩 공정을 거쳤으며, 교류 측정 결과 하이드로겔과 가장 유사한 교류를 나타내는 것은 SWCNT:H₂O = 2:1의 베르가모 원단이라는 결과를 얻을 수 있었다. 또한, 편의성, 사용성, 심리적 만족성에 관한 사용성 평가를 통해 기존 하이드로겔 패드에 비해 EMSCT가 좋은 사용성을 가진다는 결과를 얻을 수 있다.

The aim of this paper is to design and evaluate calf braces that are equipped with Electrical Muscle Stimulation (EMS) modules. These braces are intended to alleviate calf pain in PARA Taekwondo athletes. The paper also seeks to assess the effects of different textile electrode designs. PARA Taekwondo participants are at a heightened risk of injuries and pain due to the nature of this exercise, which is designed for individuals with disabilities. Additionally, there is a significant risk of strain on the lower limb muscles in PARA Taekwondo compared to regular Taekwondo. To address this issue, calf taping methods are commonly used. In this study, we develop calf EMS protective gear and aim to examine the effects of different textile electrode designs inspired by taping methods. We evaluate the differences in the effects of three different textile electrode designs through visual analog scale (VAS) and range of motion (ROM) measurements. The results show that EMS protective gear has the potential to reduce calf pain among PARA Taekwondo athletes, with electrode designs inspired by kinesiology taping providing the most effective pain relief. This research suggests that these findings may be applicable to other sports disciplines, body areas, and everyday pain relief scenarios.

This study aimed to design a knee brace with dry electrode EMS (Electrical Muscle Stimulation) for elite badminton players suffering from knee pain and assess its effectiveness in relieving pain and improving mobility. The assessment measured knee joint range of motion (ROM), Sargent jump height, and pain perception using a visual analog scale (VAS). Four experimental groups were established: stability, pain induction after 100 squats, muscle soreness induction with a regular knee brace, and muscle soreness induction with the EMS knee brace. The most suitable knee brace was selected from four samples to design the EMS knee brace. The conductive fabric was integrated into the inner surface of the knee brace to enhance EMS conductivity for the quadriceps muscles. Tensile strength tests showed that the dry electrode did not significantly affect the physical functionality of the knee brace.Regarding knee joint ROM and Sargent jump height, the EMS knee brace outperformed muscle soreness induction with a regular knee brace and wearing a standard knee brace. VAS measurements demonstrated that the EMS braces effectively alleviated pain perception in most cases. The results indicate the potential for developing EMS braces to alleviate pain and prevent injuries for athletes across various sports.
