Predicting Response to Epidural Steroid Injections for Lumbar Spinal Stenosis with Biomarkers and Electromyography.

This exploratory pilot study revealed that some biomarkers and EMG findings indicative of inflammation and nerve root injury may be predictive of improvement following ESI in patients with LSS. The results of this study will be used to inform a fully powered study to further evaluate these relationships in LSS patients.
