Randomized Controlled Trial Clinical TrialTranscutaneous electrical nerve stimulation: nonparallel antinociceptive effects on chronic clinical pain and acute experimental pain.
To investigate to what extent a single 60-minute session of transcutaneous electrical nerve stimulation (TENS) would modify chronic clinical pain, acute experimental pain, and the flexion reflex evoked in chronic low back pain patients. ⋯ The same TENS protocol had different degrees of antinociceptive influence on chronic and acute pain in chronic low back pain patients.

Randomized Controlled Trial Clinical Trial
Effectiveness of Harpagophytum extract WS 1531 in the treatment of exacerbation of low back pain: a randomized, placebo-controlled, double-blind study.
Two daily doses of oral Harpagophytum extract WS 1531 (600 and 1200, respectively, containing 50 and 100 mg of the marker harpagoside) were compared with placebo over 4 weeks in a randomized, double-blind study in 197 patients with chronic susceptibility to back pain and current exacerbations that were producing pain worse than 5 on a 0-10 visual analogue scale. The principal outcome measure, based on pilot studies, was the number of patients who were pain free without the permitted rescue medication (tramadol) for 5 days out of the last week. The treatment and placebo groups were well matched in physical characteristics, in the severity of pain, duration, nature and accompaniments of their pain, the Arhus low back pain index and in laboratory indices of organ system function. ⋯ However, subsidiary analyses, concentrating on the current pain component of the Arhus index, painted a slightly different picture, with the benefits seeming, if anything, to be greatest in the H600 group and in patients without more severe pain, radiation or neurological deficit. Patients with more pain tended to use more tramadol, but even severe and unbearable pain would not guarantee that tramadol would be used at all, and certainly not to the maximum permitted dose. There was no evidence for Harpagophytum-related side-effects, except possibly for mild and infrequent gastrointestinal symptoms.

Randomized Controlled Trial Clinical Trial
The effect of repeated epidural sympathetic nerve block on "failed back surgery syndrome" associated chronic low back pain.
To assess the therapeutic benefits of repeated epidural local anesthetic administration on pain perception and straight leg raise (SLR) in patients suffering from chronic low back pain. ⋯ 46 patients completed the study. VAS for pain was marginally lower in Group B. However, statistical significance was not demonstrated. During the hospitalization period, the SLR in both study groups significantly (0.008) improved with time. However, no difference between the groups was demonstrated. In both groups, 1 week, 1 month, and 3 months after discharge, the SLR was comparable to prestudy recordings. In Group B, at 1 week, 1 month, and 3 months after discharge, patient-generated VAS for pain were significantly (p = 0.002) higher when compared to pain scores at the time of patient discharge.

Randomized Controlled Trial Comparative Study Clinical TrialPostoperative pain after lumbar disc surgery: a comparison between parenteral ketorolac and narcotics.
Lumbar discectomy is a common elective surgical procedure but many patients still experience postoperative back pain which may delay hospital discharge. We therefore evaluated the efficacy of a parenteral non-steroidal antiinflammatory agent, ketorolac, for the management of post-surgical pain. ⋯ These results suggest that ketorolac, when used with PRN narcotics, is more effective than PRN narcotics alone for postoperative pain following lumbar disc surgery. In addition, this strategy also may contribute to early discharge from hospital after lumbar disc surgery.

Randomized Controlled Trial Clinical Trial
The reduction of chronic nonspecific low back pain through the control of early morning lumbar flexion. A randomized controlled trial.
Eighteen-month, randomized controlled trial with partial crossover. ⋯ Controlling lumbar flexion in the early morning is a form of self-care with potential for reducing pain and costs associated with chronic, nonspecific low back pain.
