  • Heating of injured tissue has been used for centuries for pain relief and reduction of muscle spasm. In physical therapy locally applied heating gents are used not only to promote relaxation and provide pain relief, but they are also used to increase blood flow, to facilitate tissue healing, and to prepare stiff joints and tight muscles for exercise. Superficial heating agents primarily cause in increases in skin and superficial cutaneous tissue temperature. Superficial heating agents such as hot packs, paraffin wax, Deep heating agents, including shortwave diathermy and continuous-wave ultrasound, can increase tissue temperature at depths ranging from 3to 5cm without overheating the skim and subcutaneous tissue.

  • 본 연구에서는 초음파를 이용하여 피부 혈관에서 그 위치에 대한 혈류 신호정보를 얻을 수 있는 펄스파(pulsed wave) 시스템을 이 분야에 응용하기 위한 가능성을 고찰하였다. 20MHz의 변환자로 수신된 신호들은 시간 영역에서 서로 비교하여 편이량을 cross-correlation방법을 사용하여 혈류속도를 구하였다. 피부의 매우 작은 혈관에서 혈류속도 거출시 발생되는 문제점에 대해 in-vitro와 in-vivo 실험을 통해서 이 방법의 효용성을 보이고 그 문제점에 대한 해결 방법을 제시한다. 시간 편이량 측정은 cross-correlation방법에 의해 정규화된 계수에서 최대점을 찾는 것이며 송신주기에 따라 반사된 수신 신호에서부터 cross-correlation방법을 사용하여 속도를 구한다. In-패패 실험을 통해 작은 튜브 내의 깊이에 대한 속도 정보를 주는 속도 profile과 이론적으로 계산된 속도 rpofile을 비교하였으며 토끼 귀 부분의 auriculares caudales에서 소동맥과 소정맥에 대한 혈류속도 profile을 구하였다. 수신 신호에서 진동에 의한 오차는 DFT를 사용하여 보정하였고 클루터 신호는 전체 수신 신호를 평균하여 하나의 기준 수신 신호를 정하여 이것에서 다른 수신 신호 값을 뺌으로써 감소시켰다.

  • Acupuncture works by stimulating peripheral sensory nerves and their endings causing an increase in cutaneous blood flow and microcirculation, as well as release of neurotransmitters, neuropeptides, and hormones. SP6 Patch is a nanoscale nontransdermal device that mildly stimulates Stomach 36 (zusanli) and other acupuncture points. As stimulation of these points has been indicated to have an effect on hypothalamic function, it is of great research interest to investigate the effect of SP6 Patch on the physiology of organs that are affected by hypothalamic regulation. Bioelectrical tissue impedance data indicative of cellular physiologic organ function, using an Electro Interstitial Scan (EIS) system, were acquired from hypothalamus, pancreas, liver, intestines, kidneys, thyroid and adrenal glands in 10 (1 male, 9 females) volunteers while wearing the SP6 Patch daily for 1 week. EIS testing was performed at baseline with no patch, 30 min after wearing the patch, and after wearing the patch 12 h/day for 1 week. Subjects were instructed to keep well hydrated during the study period. All subjects served as their own control. The hypothesis was: The SP6 Patch worn 12 h/day on the Stomach 36 acupuncture point for 1 week, may significantly improve cellular physiologic functional status of different organs measured by EIS. All tested organs achieved significant improvement in their functional physiologic status after wearing the SP6 Pach 12 h/day for 1 week compared to baseline with an overall average statistical power > 89%. Based upon these results the hypothesis was accepted as true.
