Although several anterior approaches to sciatic nerve block have been described, they are used infrequently. The authors describe a new anterior approach that allows access to the sciatic nerve with the patient in the supine position. ⋯ This approach represents an easy and reliable anterior technique for performing sciatic nerve blocks.

Randomized Controlled Trial Clinical Trial
Effect of the duration of electrical stimulation on the analgesic response in patients with low back pain.
Electrical stimulation of peripheral nerves produces acute analgesic effects. This randomized, sham-controlled, crossover study was designed to evaluate the effect of differing durations of electrical stimulation on the analgesic response to percutaneous electrical nerve stimulation in 75 consenting patients with low back pain. ⋯ The recommended duration of electrical stimulation with percutaneous electrical nerve stimulation therapy is 30 min.
