Purpose
This was a randomized, blinded study of transforaminal epidural injection of clonidine versus a similar injection of corticosteroid for acute lumbosacral radiculopathy. The hypothesis was that clonidine will be as effective as steroid for this condition.

Primary Outcome Measures:
- Pain Intensity Score at 4 Weeks as Measured by Pain Intensity Numerical Rating Scale (PI-NRS) [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]11-point ordinal scale measuring patient pain, ranging from 0 (no pain) to 10 (most severe/disabling pain).
Secondary Outcome Measures:
- Pain Intensity Score at 2 Weeks as Measured by Pain Intensity Numerical Rating Scale (PI-NRS) [ Time Frame: 2 weeks ] [ Designated as safety issue: No ]11-point ordinal scale measuring patient pain, ranging from 0 (no pain) to 10 (most severe/disabling pain).
- Pain Disability Score at 2 Weeks as Measured by the Roland-Morris Disability Questionnaire [ Time Frame: 2 weeks ] [ Designated as safety issue: No ]This scale measures functional disability due to back pain. The score of the scale is the total number of items checked, from a minimum of 0 (no disability) to a maximum of 24 (great disability). Roland MO, Morris RW.

- Pain Disability Score at 2 Weeks as Measured by Oswestry Low Back Pain Disability Questionnaire (ODI) [ Time Frame: 2 weeks ] [ Designated as safety issue: No ]This questionnaire measures a patient's permanent functional disability. The questionnaire consists of 10 sections with 6 statements each of increasing point value (from 0 to 5). The score is a percentage of the total, with higher score showing greater disability. Minimum detectable change is 10%, with a 90% CI. Change of less than this may be attributable to error in measurement.

- Pain Score at 2 Weeks as Measured by the Multidimensional Pain Inventory (MPI) [ Time Frame: 2 weeks ] [ Designated as safety issue: No ]The MPI is a comprehensive instrument comprised of 12 scales divided into three parts for assessing a number of dimensions of the chronic pain experience including pain intensity, emotional distress, cognitive and functional adaptation, and social support. Reference: Kearns RO, Turk DC, Rudy TC. The West Haven-Yale Multidimensional Pain Inventory (WHYMPI). Pain 1985; 23:345-356. Subscales were not used; the DOS WHYMPI computer program version 2.1 was used to score the instrument. Scores range from 0 (no pain) to 100 (highest pain). A score of 50 is the mean for patients with chronic pain.

Detailed Description:
Patients with approximately 3 months of low back pain and leg pain due to intervertebral disc herniation were randomized to transforaminal epidural injections of 2% lidocaine and either clonidine (200 or 400 micrograms) or triamcinolone (40 mg) (corticosteroid). Patients received one to three injections administered at about 2 weeks apart. Patients, investigators, and study coordinators were blinded to the treatment. The primary outcome was an 11-point Pain Intensity Numerical Rating Scale at 1 month. The hypothesis was that clonidine will be as effective as steroid for this condition.
