Abstract
Outpatients (151) treated with epidural or subarachnoid blocks [lidocaine with epinephrine and triamcinolone] for low-back pain not due to malignancy were questioned by mail 1-2 yr after treatment to assess their current functional status as compared with that at the time of treatment. The importance of both gender-associated differences in life functioning and the circumstances of pain onset were emphasized, while the proposition that nerve-block treatment of low-back pain was useful was supported, particularly so since the majority were cases of chronic pain. The complexity of factors in the total treatment situation, the operation of psychologic, social and economic forces in determining the outcome of treatment, and the need for detailed criteria in studies evaluating treatment effects were also emphasized.
