To report the effects of scrambler therapy in patients diagnosed with failed back surgery syndromes and to analyze the factors affecting pain before and after the therapy.
This study included 26 patients (12 males and 14 females). The Oswestry Disability Index (ODI) and Brief Pain Inventory (BPI) before and after scrambler therapy, Beck Depression Inventory (BDI) score before therapy, and residual pain after therapy were assessed. The changes in the ODI, BPI, and residual pain before and after the therapy were analyzed using the Wilcoxon signed rank test. Spearman correlation analysis and Fisher's exact test were used to confirm the correlation between BDI and other factors. Multiple regression analysis was used to identify independent factors predicting residual pain, posttherapy ODI, and posttherapy BPI.
The ODI changed from 25.69 ± 7.98 to 21.80 ± 9.41 ( < 0.05), and the BPI changed from 68.96 ± 18.00 to 61.62 ± 20.27 after scrambler therapy ( < 0.05). In addition, residual pain changed from 100 to 76.15 ( < 0.05). The BDI was negatively correlated with the duration of scrambler therapy and positively correlated with the initial OPD and BPI. In multiple regression analysis, residual pain was significantly correlated with the BDI ( < 0.05).
Scrambler therapy can be used to change the total scores of the ODI and BPI after 5 sessions of treatment. Also, residual pain was significantly related to the BDI. Clinical significance of depression severity on pain should be further investigated via prospective studies.
报告使用紊乱仪治疗失败性腰椎术后综合征患者的效果，并分析治疗前后疼痛的影响因素。
本研究纳入 26 例患者（男 12 例，女 14 例），治疗前后采用 Oswestry 功能障碍指数（ODI）和简明疼痛量表（BPI）评估，治疗前采用贝克抑郁量表（BDI）评估，治疗后评估残余疼痛。采用 Wilcoxon 符号秩检验分析治疗前后 ODI、BPI 和残余疼痛的变化，采用 Spearman 相关分析和 Fisher 确切概率法确认 BDI 与其他因素的相关性，采用多元逐步回归分析识别预测残余疼痛、治疗后 ODI 和治疗后 BPI 的独立因素。
ODI 从 25.69±7.98 降至 21.80±9.41（<0.05），BPI 从 68.96±18.00 降至 61.62±20.27（<0.05）。此外，残余疼痛从 100 降至 76.15（<0.05）。BDI 与紊乱仪治疗持续时间呈负相关，与初始 ODI 和 BPI 呈正相关。多元逐步回归分析显示，残余疼痛与 BDI 显著相关（<0.05）。
紊乱仪治疗 5 次后可改变 ODI 和 BPI 的总分。残余疼痛与 BDI 显著相关。需要进一步通过前瞻性研究探讨抑郁严重程度对疼痛的临床意义。
