The fascicular anatomy of the sciatic nerve may not influence the muscular activity of the biceps femoris after applying percutaneous electrical nerve stimulation: a randomized clinical trial.

Background: Electrical nerve stimulation is an effective therapeutic tool in the field of rehabilitation for the management of musculoskeletal conditions.

Objective: To analyze the muscle activity of the short head of the biceps femoris (SHBF) and long head of the biceps femoris (LHBF) after the application of percutaneous electrical nerve stimulation to the common fibular versus tibial nerve compartment of the sciatic nerve.

Methods: Thirty-eight healthy subjects received electrical stimulation (asymmetric biphasic rectangular waveforms) through a needle in the sciatic nerve.
