Needle electromyography predicts outcome after lumbar epidural steroid injection

Abstract

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.

The Relationship Between History and Physical Examination Findings and the Outcome of Electrodiagnostic Testing in Patients With Sciatica Referred to Physical Therapy

“…12,13 This is significant in terms of this investigation because it improves the likelihood that patients were properly classified based on the results of their EDX testing. In this investigation, 19 of 38 (50.0%) patients were classified as having evidence of radiculopathy, a percentage that is consistent with previous research 5,8,15,26 ; therefore, the likelihood that patients were misclassified based on their EDX test findings is low, given the demonstrated effectiveness of the 6-muscle EMG screening examination used in this study for identifying EMG-confirmable radiculopathies. 12,13 The results of this investigation are likely clinically meaningful because they suggest that the relationship between select patient history and physical examination findings and the outcome of EDX testing is weak and appears to be of limited clinical usefulness.…”

“…However, recent studies have suggested that the presence of radiculopathy found on EDX testing may be a favorable prognostic factor for recovery. 5,8 Therefore, establishing history and/or physical examination findings in patients with sciatica that could accurately predict the outcome of EDX testing would benefit patients and clinicians. The purpose of this study was to investigate the relationship between select patient history and physical examination findings and the outcome of EDX testing in patients with sciatica referred to physical therapy.…”

“…[13] Tedaviye Yanıtın Tahmini Tartışmalı olmakla birlikte, az sayıda çalışmada, EMG-pozitif radikülopati olgularının epidural steroid enjeksiyonlarına ve cerrahi tedaviye daha iyi yanıt verdiği gösterilmiştir. [14][15][16] …”

Electrodiagnostic Testing Before Epidural Steroid Injections

“…The researchers concluded that patients with negative NEE should not be excluded from a trial of LESI. We performed a prospective, multiple regression study and found that abnormal NEE consistent with EDX impression of radiculopathy moderately predicted long‐term improvement in pain after LESI [17]. Positive EDX evidence of radiculopathy was predictive of statistically significant better improvement in both pain and functional scores compared with no EDX evidence of radiculopathy, although the patients with normal NEE also tended to favorably respond to LESI [17].…”
