背景與目的：柯雷氏骨折常因跌倒、運動傷害及車禍而發生，尤其在骨質疏鬆的老人及停經的婦女更是常見。因此本研究的目的是評估經皮神經電刺激（TENS)對柯雷氏骨折病人術後疼痛的療效。
材料與方法：將36位合乎納入標準的柯雷氏骨折病人術後隨機分成兩組，每組18人如下：（1)實驗組，術後接受TENS治療，每日20分鐘，連續5日；（2)對照組，方法與實驗組相同，但施行假TENS治療。主要評估是根據Visual Analogue Scale（VAS），次要評估是根據pain control analgesia（PCA）和NSAID使用的總劑量以及嘔吐發生次數。
結果：實驗組於術後第一天到第五天TENS電刺激後的VAS減少都比對照組大，但實驗組從術後第二天到第五天的TENS電刺激前的VAS與對照組相似；TENS不能減少PCA、 NSAID使用的總劑量和嘔吐的次數。
結論：經皮神經電刺激能緩解柯雷氏骨折病人的術後疼痛，但這種止痛效果是短暫，因此推論可應用於臨床需要短暫止痛的病人。
Background and Purpose: The most etiology of Colles’ fracture is resulting from old age associated with osteoporosis and falling down on the ground. They are poor tolerance to the non-steroid anti-inflammatory drug (NSAID) in old aged patients, and that easily results in occurrence of gastric ulcer even perforation. There is an important topic how to decrease to dose of NSAID in post-operative patient. Many studies report that transcutaneous electric nerve stimulation (TENS) has analgesic effect. Therefore, the aim of the present study was to assess the analgesic effect of TENS on post-operative pain in patients with Colles’ fracture.
Materials and Methods: The present study was a randomized, double blinded controlled clinical trial. A total of 36 patients with Colles’ fracture, and all of them qualified the inclusion criteria and were divided randomly into two groups of 18 patients as follows: 1) experimental group, received TENS treatment continuous 5 days, 20 min in duration every day; control group, the methods were identical the experimental group, but received sham TENS treatment (without electric stimulation). Primary measure was according the visual analogue scale (VAS), and secondary measure was according to the counts of pain control analgesia (PCA), nausea, and the dose of NSAID.
Results: The decrease of VAS was greater in the experiment group than that in control group from first to 5th days after operation, whereas the VAS was similar between 2nd to 5th days prior to the TENS after operation. The counts of PCA, nausea and the dose of NSAID were not significant difference between experiment and control groups.
Conclusion: TENS may transient relief the post-operative pain in patients with Colles’ fracture, suggesting TENS may use in the patient who need short-term analgesia.
