摘要

本研究為評估治療用超音波深部熱療後對人體深部組織之影響。以55名健康志願者提供之90個背都，自第二腰椎至第五腰椎旁肌，長10公分寬4公分區域，施以不同劑量與時間之超音波。並採用數字溫度計du8ls及AK8深部組織溫度探針測量溫度。每隔2分鐘計錄一次，測量深度由皮下5公分深起，每0.5公分作一記錄 ，至皮下0.5公分止。將所測之背肌隨機分為七組：A組30個背肌皆施以1.5瓦特／平方公分之超音波5分鐘；AA組l0個背肌，1.5瓦特／平方公分，10分鐘；B組10個背肌，1.0瓦特／平方公分，5分鐘；BB組l0個背肌，1.0瓦特／平方公分，10分鐘；C組l0個背肌，0.5瓦特／平方公分，5分鐘；CC組10個背肌，0.5瓦特／平方公分，10分鐘；CN組為對照組，10個背肌，0瓦特／平方公分，5分鐘。結果在剛施作完超音波時，A組最多可增5.5°C（在皮下4.5公分處）平均1.84°C；AA組最高增6.0°C（皮下4公分處）平均1.93°C；B組最高增3.2°C（皮下5公分處）平均1.6°C；BB組最高增3.5°C（皮下5公分處）平均1.79°C；C組最高增2.0°C（皮下5公分處）平均0.64°C；CC組最高增3.2°C（皮下5公分處）平均1.5°C；CN對照組溫度大部分不升反略降。本實驗發現作完超音波後在較深層組織溫度增高較多。所增加之溫度可維持約10分鐘至15分鐘後降回未作超音波前之溫度。施作10分鐘之組溫度之上升之維持時間皆比5分鐘之組大。由此可以證明臨床應用超音波治療時，在深部組織產生之熱度與使用超音波之劑量與時間有正值係數相關。

Fifty volunteers' 90 backs (10 cm in length & 4 cm in width area at bilateral second to fith lumbar paraspinal muscle) were treated by therapeutic ultrasound with different intensities & times to evaluate the effect of heat produced by ultra-sound diathermy. The temperatures were measured with digital thermometer & AK 8 needle tissue electrode and rocorded every two minute interval at every 0.5 cm depth (0.5cm to 5cm from skin). The muscles were divded into seven
groups randomly. Group A;30 backs received ultrasound at an intensity of 1.5 watts/c㎡ for 5 minutes. Group AA; 10 backs, 1.5w,/c㎡ . 10 min. Group B: 10 backs, 1.0 w/c㎡, 5 min. Group BB: 10 backs, 1.0 w/c㎡, 10 min. Group C: 10 backs. 0.5 w/c㎡ , 5 min. Group CC: 10 backs 0.5 w/'c㎡, 10 min. Group CN: 10 backs, 0 w/'c㎡, 5 min. for control. The result showed Group A: highest rise 5.5°C at 4.5 cm depth from the skin, mean: 1.84°C; Group AA: highest rise 6.0°C at 4cm depth, mean 1.93°C; Group B: highest rise 3.2°C at 5 cm depth, mean: 1.6°C: Group BB: highest rise 3.5°C at 5cm depth mean: 1.79°C; Group C: highest rise 2°C at 5 cm. mean: 0.64 °C; Group CN: decrease slightly. It was found that that the highest rise of temperature occured in the deeper area of tissue and decreased with tissue depth. All temperature rise decreased with time passing and returned to initial temperature within 10 to 15 minutes. Groups of 10 minute treatment got higher temperature rise and manitained longer periods than those of groups of 5 minute treatment with statistics significance.
