Patients with higher education, lower age, full-time working status and lower fear-avoidance beliefs typically had better outcomes following caudal epidural injections for chronic unilateral lumbar radiculopathy, according to recently published study data.
A total of 116 patients with chronic unilateral lumbar radiculopathy were included in the sham-controlled clinical trial on epidural injection of glucocorticoids. The researchers used the Oswestry Disability Index (ODI) and the VAS score for low back pain and leg pain as outcome measures, defining success at follow-up as a score of 17.5 or lower for VAS leg pain, 22.5 or lower for VAS back pain and 20 or lower for Oswestry Disability Index (ODI). They also used logistic multivariable regression analysis to evaluate 15 clinically relevant variables, including demographic, psychosocial, clinical and radiological data.
