Comparison of Electromyography Activity in Accordance with Contact Pad Type during the Use of a Standing Table for Pediatric Patients with Brain Lesions

뇌병변 소아환자의 기립보조기 사용 시 접촉 패드 유형에 따른 근활성도 비교

This study conducted a comparative analysis of the contraction pattern of trunk and lower limbs muscles of handicapped children with brain lesions during the use of foam pad and air pad for fixing a standing table to the body for pediatric patients with brain lesions using a standing table product applied with a pneumatic air fitting system. There was a difference in the measurement of muscle strength activity by muscle in accordance with pad type (foam pad vs. air pad). A large difference was found with big movements (movements of eating), while a small difference was discovered with small movements (writing and reading movements). This was found to furnish a little more comfort to users compared with the existing foam pad during the use of a standing table product applied with a pneumatic air fitting system.

본 연구에서는 Pneumatic air fitting system을 적용한 기립보조기 제품을 뇌병변 소아환자를 대상으로 기립보조기의 신체 고정용 폼패드(foam pad)와 에어패드(air pad) 사용 시, 뇌병변 장애아동들의 체간 및 하지근육의 수축 양상을 비교 분석하였다. 연구결과, 패드(foam pad vs. air pad) 유형에 따른 근육별 근력 활성도는 차이가 있었다. 이러한 차이는 큰 동작(식사동작)에서 크게 나타나고, 작은 동작(쓰기동작, 읽기동작)이 작게 나타났다. 이는 Pneumatic air fitting system을 적용한 기립보조기 제품 사용 시, 기존 폼패드에 비해 사용자에게 좀 더 편안함을 제공하는 것으로 나타났다.
