국소 진동자극과 과제 지향적 훈련의 동시 적용이 뇌졸중 환자의 상지 기능 개선에 미치는 효과 = Effects of Simultaneous Application of Focal Vibration Stimulation and Task-Oriented Training in the Improvement of Upper Extremity Motor Function after Stroke

다국어 초록 (Multilingual Abstract)

Purpose : The purpose of this study was research the effects of simultaneous application of focal vibration stimulation and task-oriented training to improve upper extremity motor function after stroke.
Method : The study period was from January, 2018 to April, 2019, to 23 patients who were suitable for selection criteria. Participants were divided into two groups: a vibration stimulation task-oriented training group, and task-oriented training group. Training was conducted a total of 20 sessions, five times a week for 30 minutes a day for four weeks. the amount of use of the affected and unaffected side by accelerometers, and BBT, ARAT was measured with a pre-test, a post-test.
Result : Both groups showed statistically significant changes in BBT, ARAT, amount of use of the affected and unaffected side. The results of the comparison between the groups, amount of use of the affected side, and BBT and grasp and gross movement item of the ARAT showed significant changes in the experimental group compared to the control group.
Conclusion: It found that it was more effective when providing simultaneous application of focal vibration stimulation and task-oriented training than when task-oriented training. In future studies, a comparative study involving a group with only vibration stimulation is required for a large number of subjects for generalization.

연구목적 : 본 연구의 목적은 국소 진동자극과 과제 지향적 훈련을 동시 적용하였을 때 뇌졸중 환자의 상지 운동 기능의 개선에 대한 효과를 알아보는 것이다.
연구방법 : 연구 기간은 2018년 1월부터 4월 까지 진행되었으며, 대상자 선정기준에 적합한 23명을 대상으로 실시되었다. 연구 대상자들은 진동자극과 과제 지향적 훈련의 동시적용한 실험군, 과제 지향적 훈련만 실시한 대조군으로 나눠졌다. 두 그룹은 4주간, 주 5회, 일 30분의 중재를 수행하였으며, 가속도계를 사용하여 환측과 건측의 사용량, BBT, ARAT를 중재 전후로 시행하였다.
연구결과 : 두 그룹 모두 BBT와 ARAT, 환측과 건측의 사용량에서 통계학적 유의한 변화를 보였다. 그룹 간 비교 결과, 환측의 사용량, BBT, ARAT 중 grasp와 gross movement 항목에서 실험군은 대조군보다 유의한 변화를 나타냈다.
결론: 손목폄근에 국소 진동자극과 과제 지향적 훈련의 동시적용은 과제 지향적 훈련만 실시하는 것보다 상지 기능 개선에 더 효과적이었다. 추후 연구에서는 본 연구의 일반화를 위해 진동자극만 실시한 그룹을 포함하고, 더 많은 연구대상자를 대상으로 시행되어야 할 필요가 있다.
