Abstract

This study was to investigate the effects of the hot compress pack on alleviating local muscular discomfort, stiffness in limbs as well as the chronic pains such as migraine in terms of hemodynamics. In this study, the hot compress band was put on the neck and the local physiological change on the stimulation site and the cranial blood circulation change were examined. We recruited healthy volunteers (n=8, mean age: 32.13 (4.61)), who participated in the magnetic resonance imaging (MRI) study. Local skin color and temperature were measured for the local effect of the hot compress band and the changes of intra-cranial and extra-cranial blood vessels were examined with MR angiography (MRA) images. The skin temperature increased from $36.4^{\circ}C$ at the rest condition to $36.7^{\circ}C$ and $37.1^{\circ}C$ after 15 min and 30 min stimulation, respectively. The change of the extra-cranial blood vessels between pre-stimulation and post-stimulation of 30 min was significantly increased (+38.8%), while the change of the intra-cranial blood vessels was negligible. In this study, we demonstrated that the hot compress band on the neck yielded the increase of local skin temperature on the stimulation site and it made an effect on the extracranial circulation. In conclusion, the stimulation with a hot compress could facilitate the blood circulation, causing to relieve the muscular discomfort, stiffness in limbs as well as the chronic pains such as migraine.

본 연구는 찜질 자극이 국소 통증을 완화시킬 뿐만 아니라 편두통과 같은 만성 질환의 통증 완화에 효과적으로 애용되고 있는 이유에 대한 근거를 혈류 역학적인 측면에서 고찰하고자 한다. 이를 위해 찜질 자극에 의한 자극 부위에서의 국소 혈류 변화가 일어나는 것을 관측하고, 이를 통해 두개 내 외부의 혈액 순환에 어떠한 변화를 야기하는지를 정상인 피험자 (n=8, 평균나이: $32.13{\pm}4.61$) 를 대상으로 자기공명영상 시스템을 이용하여 관측하였다. 국소 혈류변화는 찜질 자극에 의한 피부 색깔 및 온도 변화를 통하여 관측하고자 하였고, 두개 내 외부 혈관의 자극에 따른 변화를 자기공명혈관조영술을 통해 관측하고 영상을 분석하여 비교하고자 하였다. 찜질 자극 전 $36.4^{\circ}C$에서 자극 15분 후 $36.7^{\circ}C$, 그리고 자극 30분 후 $37.1^{\circ}C$ 로 피부온도가 상승한 것으로 나타났으며, 찜질 자극이 시작되는 시점과 자극 30분 후의 혈관 영상 분석 결과를 살펴보면 두개 내부 혈관에서는 유의한 변화를 보이지 않은 반면, 두개 외부 혈관에서는 찜질 자극 후 상당한 혈류 신호의 변화를 보여주었다(+38.8%). 결과에서 보듯이 찜질 자극 부위의 이러한 국소 온도의 변화와 두개 외의 혈류의 변화를 통하여 찜질 자극이 국소적으로는 근육 통증 및 편두통과 같은 만성질환의 통증을 완화시키는 효과를 발휘하고 더 나아가 혈액 순환을 촉진시키는 작용을 통하여 전신에 미치는 결림 현상 및 통증의 완화에 실질적으로 효과를 보일 수 있게 되는 것으로 사료된다.
