Abstract

The purpose of this study was to determine whether olfactory stimulation would improve spasticity, balance ability and quality of life in stroke patients. Twenty-one stroke patients were recruited and were randomly divided into two groups: olfactory stimulation group (n=10) and sham stimulation group (n=11). Participants in both groups received conventional physical therapy for 30 minutes before the intervention. Additionally, subject in the olfactory stimulation group performed olfactory stimulation using lavender oil for 6 minutes (2 minx3 set), five times a week for two weeks, while the sham stimulation group conducted olfactory stimulation using water for the same amount of time. Composite-Spasticity-Score was used to assess spasticity level of ankle plantar-flexors. Dynamic balance was measured using a TUG. Postural-sway distance was measured using a force platform. Quality of life were measured by SF-36. There was no significant difference within group and between the groups in the spasticity. Significant improvement in postural-sway and TUG were observed in the olfactory stimulation group compared to the sham stimulation group (p<0.05). The Mental Componnt Summary of the SF 36 in the olfactory stimulation group improved significantly greater than the sham stimulation group (p<0.05). Our findings indicate that olfactory stimulation is beneficial and effective to improve balance ability and quality of life in stroke patients.

본 연구는 만성 뇌졸중 환자를 대상으로 2주간 후각 자극이 균형, 경직 및 삶의 질에 미치는 효과를 규명하기 위하여 실시되었다. 단일맹검 및 사전 무작위 임상시험으로 진행되었으며, 21명의 만성 뇌줄중 환자는 무작위로 후각자극군(n=10)과 속임 후각자극군(n=11)으로 배정되었다. 후각자극 군은 라벤더 오일을 2주간 주 5회, 총 10회 시행하였고, 속임 후각자극 군은 물을 적용하였다. 경직은 Composite Spasticity Score (CSS)를 사용하여 측정하였고, 정적 균형은 힘판(force plate), 동적균형은 Timed up and go test(TUG), 삶의 질은 Short-Form 36 items(SF-36)를 사용하였다. 훈련 후 후각자극 군이 속임 후각자극 군에 비해 정적균형이 유의하게 개선되었으며(p<.05), 경직과 동적균형은 집단 간 유의한 차이가 없었다. 또한, 후각자극 군에서 SF 36의 정신적 건강요약과 총점이 속임 후각자극 군에 비해 유의하게 개선되었다. 본 연구는 후각자극이 만성 뇌졸중 환자의 정적균형과 삶의 질을 효과적으로 향상시킴을 증명하였다.
