Needle electromyography (NEE) would be more valuable if it could predict outcomes after lumbar epidural steroid injections (LESIs) in lumbosacral radiculopathy (LSR).
We investigated the predictive value of NEE for outcome after LESI compared with other known predictive variables in 89 subjects with clinical LSR. Seventy patients completed the study, which included diagnostic lower extremity NEE and LESI. Outcome measures included changes in pain, physical function, and psychosocial function [assessed using the Pain Disability Questionnaire (PDQ)].
NEE was an independent predictor of long-term pain improvement after LESI and was not predictive of PDQ functional improvement. A regression model, with NEE as one of several independent variables, showed strong outcome-predictive ability.
NEE is an independent predictor of long-term pain relief after LESI for LSR. Abnormal NEE is predictive of better outcome than normal NEE. A regression equation including NEE and other independent predictors was predictive of pain and functional outcomes.
如果针肌电图（NEE）能够预测腰椎硬膜外类固醇注射（LESI）治疗腰骶神经根病（LSR）后的结果，它将更具价值。
我们研究了 89 例临床 LSR 患者的 NEE 对 LESI 后结果的预测价值，并与其他已知的预测变量进行了比较。70 名患者完成了这项研究，其中包括诊断性下肢 NEE 和 LESI。结局指标包括疼痛、身体功能和心理社会功能的变化（使用疼痛残疾问卷[PDQ]评估）。
NEE 是 LESI 后长期疼痛改善的独立预测因素，而不是 PDQ 功能改善的预测因素。包含 NEE 作为几个独立变量之一的回归模型显示出很强的结局预测能力。
NEE 是 LESI 治疗 LSR 后长期缓解疼痛的独立预测因素。异常的 NEE 比正常的 NEE 预测更好的结果。包括 NEE 和其他独立预测因子的回归方程可预测疼痛和功能结局。
