Randomized Controlled Trial Clinical Trial
[Caudal epidural injection in the management of lumbosacral nerve pain syndromes].
The effect of epidural steroid injections was assessed in 39 patients with lumbar nerve root compression syndromes in a double-blind controlled trial, the patients were allocated at random to 3 groups. In group A (n = 13) the patients received a caudal epidural injection of 1 ml (7 mg) bethametason (Diprophos) in 10 ml normal saline and 20 ml local anesthetic (Lignocaine 1%). The second group B (n = 13) received a caudal epidural injection of 20 ml local anaesthetic (Lignocaine 1%) and 10 ml normal saline. ⋯ After four weeks there was no significant difference. No major complications or side effects were seen in our trial. The raised leg sign due to epidural steroid injection showed better results in comparison to steroid injection around of the sacral hiatus were seen.

Randomized Controlled Trial Comparative Study Clinical TrialThe effect of stimulus frequency on the analgesic response to percutaneous electrical nerve stimulation in patients with chronic low back pain.
Low back pain (LBP) is one of the most common medical problems in our society. Increasingly, patients are turning to nonpharmacologic analgesic therapies such as percutaneous electrical nerve stimulation (PENS). We designed this sham-controlled study to compare the effect of three different frequencies of electrical stimulation on the analgesic response to PENS therapy. Sixty-eight consenting patients with LBP secondary to degenerative lumbar disc disease were treated with PENS therapy at 4 Hz, alternating 15 Hz and 30 Hz (15/30 Hz), and 100 Hz, as well as sham-PENS (0 Hz), according to a randomized, cross-over study design. Each treatment was administered for a period of 30 min three times per week for 2 wk. The pre- and posttreatment assessments included the health status survey short form and visual analog scales for pain, physical activity, and quality of sleep. After receiving all four treatments, patients completed a global assessment questionnaire. The sham-PENS treatments failed to produce changes in the degree of pain, physical activity, sleep quality, or daily intake of oral analgesic medications. In contrast, 4-Hz, 15/30-Hz, and 100-Hz stimulation all produced significant decreases in the severity of pain, increases in physical activity, improvements in the quality of sleep, and decreases in oral analgesic requirements (P < 0.01). Of the three frequencies, 15/30 Hz was the most effective in decreasing pain, increasing physical activity, and improving the quality of sleep (P < 0.05). In the global assessment, 40% of the patients reported that 15/30 Hz was the most desirable therapy, and it was also more effective in improving the patient's sense of well-being. We conclude that the frequency of electrical stimulation is an important determinant of the analgesic response to PENS therapy. Alternating stimulation at 15-Hz and 30-Hz frequencies was more effective than either 4 Hz or 100 Hz in improving outcome measures in patients with LBP. ⋯ The frequency of electrical stimulation seems to be an important determinant of the analgesic efficacy of percutaneous electrical nerve stimulation. Mixed low- and high-frequency stimulation was more effective than either low or high frequencies alone in the treatment of patients with low back pain.

Randomized Controlled Trial Clinical Trial
A randomized controlled trial of nonpharmacologic approaches for relief of low back pain during labor.
Low back pain is common during labor. Our randomized controlled trial compared the effectiveness of 3 nonpharmacologic approaches for relief of back pain. ⋯ Intracutaneous sterile water injections are more effective than standard care (back massage, bath, and mobilization) or transcutaneous electrical nerve stimulation for relieving low back pain during labor.

Randomized Controlled Trial Comparative Study Clinical Trial
Influence of estrogen-progestin treatment on back pain and disability among slim premenopausal women with low lumbar spine bone mineral density. A 2-year placebo-controlled randomized trial.
A 2-year randomized controlled trial. ⋯ It seems that this regimen may have alleviating effects on nighttime back pain and functional back disability in slim osteopenic premenopausal women.

Randomized Controlled Trial Comparative Study Clinical Trial
Percutaneous electrical nerve stimulation for low back pain: a randomized crossover study.
Low back pain (LBP) contributes to considerable disability and lost wages in the United States. Commonly used opioid and nonopioid analgesic drugs produce adverse effects and are of limited long-term benefit in the management of this patient population. ⋯ In this sham-controlled study, PENS was more effective than TENS or exercise therapy in providing short-term pain relief and improved physical function in patients with long-term LBP.
