| 中文摘要 | 臨床上超音波應用於肌腱炎,韌帶拉傷,減少粘黏,傷口癒合等症狀。 以達到減少疼痛,加速組織癒合,放鬆關節攣縮的效果。其作用機轉主要為超音 波在穿透組織時被組織吸收而產生的熱效應及機械式的振動效應。其中熱效應的 治療機轉,是由於組織溫度昇高兩增加組織癒合的速度。本篇研究使用超音波於 不同的部位,如關節及肌肉,探討在深淺部溫度的改變。使用分離的雞腿作研究 材料,除去表皮,使超音經由介質,直接進去關節或肌肉組織。同時分離之雞腿 少去關節及肌肉部位血流不均勻的因素,提供一個簡化模型單純比較臨床上使用 之超音波使關節及肌肉組織產生溫度變化的不同。臨床上使用之超音波設在 1.5W/cm�握妤j度,1MH之頻率,以移動旋轉方式使用7分鐘,應用前及應用後1, 5,10,20分鐘,分別測量應用部分表面及1.5公分深之溫度。結果顯示不論應用 於關節或肌肉部位其深部或淺部溫度均在應用1,5,10,20分鐘後其溫度在統計 上有意義的增加 (p<0.05)。比較應用後1分鐘及應用前關節及肌肉的溫度增加則 發現並無明顯差別(p>0.05),但深部的改變大於表面之溫度(p<0.05)。這結果顯示 肌肉組織與關節部位之結締組織均可使用超音波有效的增加組織溫度。此結果除 了支持超音波對結締組織的病變應用外,也提供使用超音波改善肌肉病變如肌膜 炎或肌肉拉傷等肌肉的治療,對於使用在肌肉部位,組織溫度的增加,血流的改 變及使用之參數均須再更進一步研究。(中華物療誌1995;20(1):10-17) |
| 英文摘要 | Therapeutic ultrasound is applied in the treatment of tendinitis, ligament sprain, woundcare, and scar adhesion. The mechanism of therapeutic ultrasound includes thermal andmechanical effect. The principal effect of ultrasound is elevation of tissue temperature andaccelerating tissue repair. To study the superficial and deep temperature change in jointand muscle areas after ultrasound diathermy, isolated chicken leg model was used in thisstudy. The skin and subcutaneous tissue was removed, so that the ultrasound could enterthe applied joint and muscle tissue through media directly. The isolated chicken leg alsoexcluded the factor of different blood flow in the joint and muscle areas, and provided a verysimplified model to compare the effect of temperature change in the joint and muscle.Clinical used ultrasound machine was set in the intensity of 1.5 W/cm2, frequency of I MHz,and applied with circular moving technique for 7 minutes. The superficial temperature atthe surface, and the deep temperature at 1.5 cm depth were measured before ultrasounddiathermy, and 1 minute, 5 minutes, 10 minutes, 20 minutes after the application of ultrasound. The results showed that the superficial and deep temperatures of joint and musclewere significantly greater than the pre-test temperature (p<0.05). Comparing the temperature rise at 1 minute after ultrasound to pre-test temperature, for both joint and muscleareas, the temperature rise at the deep sites is greater than the rise at superficial site(p<0.05). However, there is no significant difference between the temperature rise at jointand muscle areas (p>0.05). These results demonstrated that in the isolated chicken legmodel, both joint and muscle tissue could be heated effectively in the superficial and deepsites with therapeutic ultrasound. This result supports the common use of ultrasound in thetreatment of problems in tendon, ligament and capsule around the joints, also suggests theeffective use of ultrasound in the treatment of muscle problems, such as myofacial pain,muscle strain. The temperature increase, blood flow change in the muscle, and the optimalparameter of therapeutic ultrasound for muscle need further investigation. (JPTA ROC1995;20(1):10-17) |
