To determine if improvements in pain after epidural steroid injections (ESIs) were related to electromyographic (EMG) findings in patients with radicular symptoms and clinical findings consistent with radiculopathy. ⋯ Mean leg and back pain scores improved significantly after ESI in all 3 EMG groups: those with positive, normal, and equivocal findings. Results of this study do not suggest that ESI is contraindicated in patients with normal EMG findings.
