Abstract

The purpose of this study is to investigate the recovery of sensation and the restoration of upper limb function according to transcranial direct current stimulation over the primary somatosensory cortex in patients with chronic stroke with sensory deficit. 20 patients with chronic stroke divided into 10 experimental groups and 10 control groups. Patients received transcranial direct current stimulations over the primary somatosensory cortex on the side of the stroke lesion, and The control group applied sham tDCS to the same location. Intervention was conducted 5 times a week, 20 minutes per session for a total of 2 weeks. Assessment was performed using the Erasmus MC modifications to the Nottingham Sensory Assessment(EmNSA), Semmes-Weinstein monofilament examination(SWME) for somatosensory, and Fugle-Meyer Assessment(FMA), Motor Activity Log(MAL), and accelerometer for upper extremity function. Assessment was conducted before and after the intervention. As a result of the study, the experimental group showed a significant improvement in the overall tactile sense, proprioception, cortical sense, and perception sensitivity than the control group, and showed a statistically significant difference in the usage amount of the upper limb. Based on the results of this study, it is thought that the possibility of effective clinical application of transcranial direct current stimulation for recovery of somatosensory and upper extremity function is thought to be increased.

본 연구의 목적은 감각 결손이 있는 만성 뇌졸중 환자를 대상으로 경 두개 직류 전류 자극을 체성감각피질에 적용했을 때, 감각의 회복과 상지 기능의 회복을 알아보고자 하는 것이다. 만성 뇌졸중 환자 20명을 실험군 10명, 대조군 10명으로 나누어 실시하였다. 실험군은 환측 체성감각피질에 경 두개 직류 전류 자극을 적용하였으며, 대조군은 위상 자극을 실시하였다. 중재는 총 2주간, 10회, 회기 당 20분씩 진행되었다. 체성감각 평가는 The Erasmus MC modifications to the (revised) Nottingham Sensory Assessment(EmNSA), Semmes-Weinstein monofilament examination(SWME), 상지기능 평가는 퍼글마이어평가(FMA), 운동 활동 척도(MAL), 가속도계를 사용하였다. 연구 결과, 실험군은 대조군보다 전체적인 촉각 감각과 고유수용성 감각, 피질 감각, 지각의 민감도에서 유의한 개선을 보였으며, 환측 상지의 사용량에서 통계학적 유의한 차이를 나타냈다. 본 연구 결과를 기반으로 체성감각 회복과 상지기능의 회복을 위한 tDCS의 효과적인 임상 적용의 가능성을 높일 수 있을 것으로 생각된다.
