摘要

本研究評估干擾波對背痛術後仍有嚴重背疼、腿痛的止痛效果共計26例。其申男性17人，女性9人。平均年齡46.5±11.7歲。椎間盤突出者最多佔16例。共分3組，術後1週內即接受干擾波治療者為急性組9人，1週後至半年者為亞急性組6人，其它為慢性組11人。以術後完全無法忍受的疼痛為10分、中等程度為5分，不痛為0分，作術前、干擾波治療前後疼痛的比較。結果以急性組效果最好，與亞急性、慢性組比較具有統計上差異。另以單純椎間盤突出術後仍有異常疼痛卻未接受干擾波治療患者8人作為急性組的對照組，結果顯示干擾波對背痛術後疼痛是有所助益的。故干擾波可減輕背痛術後的疼痛，尤其是原因單純椎間盤突出術後急性期的止痛，不失為一有效可行的方法。

The purpose of this study was to evaluate the effectiveness of interferential therapy for pain control of severe back or leg pain after back surgery.
Twenty six patients were studied (17 males, 9 females) with mean age of 46.5 + 11.7 years. Three different groups of patients based on the time of receipt of interferential therapy after surgery were analysed. The acute group received therapy within one week, while subacute group between the second week and half an year after operation, chronic group was consisted of all other cases. Herniation of intervertebral disc was the most common cause of back pain in the study.
The degree of pain was estimated by numerical score between 0 and 10 before and after operation. Ten represents very intensive pain, 5 is moderate pain, but o is no body .The higher the score, the more severity of pain is indicated.
In addition, 8 patients as control group after disectomy or laminectomy without interferential therapy is compared with the acute group.
The results were (1) The effectiveness of pain relief by inter- ferential therapy in acute group had significant difference statiscally when compared with subacute and chronic group. All of acute group patients had improvement in pain after therapy. However, there were only 2 of 6 patients in subacute group and 6 out of 11 patients in chronic group had improvement in pain after therapy ( X2 = 8.06, p＜ 0.025 ). To analyze the degree of pain with numerical score, it showed that the scores before and after interferential therapy were 8.00 ±1.32 and 2.44±1.24 in acute group, 7.17 ±1.72 and 6.50 ±2.26 in subacute group, 6.73±2.61 and 5.55 ±2.38 in chronic group, respectively. There were significant differences for both acute and chronic group (paired t-test, t=12.5, p＜0.001; t=2.36, p＜0.025 ) ,but not for subacute group ( t=1.58, p＞0.05). (2) Acute group patients alsoe had more satisfactory results than control group without interferential therapy. In control group, the numerical score of the second to third day after back surgery was 6.50 ±1.41, while it was 5.00 ±1.93 at discharge. Significant difference between acute group and chronic group was found (t=3.29 , p＜0.01).
In conclusion, interferential therapy is, more effective for pain relief in acute than subacute or chronic group postoperatively, especially in patients with herniation of intervertebral disc.
