The Application of Neuromodulation in Sciatic Nerve

Overview

The objective of this study will be to analyze the muscle activity of the short head (SHBF) and long head of the biceps femoris (LHBF) after the application of ultrasound-guided percutaneous neuromodulation (NMP) in the tibial or common fibular nerve compartment of the sciatic nerve. Authors will recruit healthy subjects and they will receive asymmetric biphasic rectangular current through a needle into the sciatic nerve. The sample was divided into two groups: one to which the technique was applied in the lateral compartment and another group, in the medial compartment of the nerve. The protocol used was 5 seconds of stimulation, 55 seconds of rest for 5 minutes at a frequency of 100 Hz and a phase duration of 350 microseconds. The electrical activity (recruitment of muscle fibers and maximum contraction) of the SHBF and LHBF and the muscle strength of the knee flexors were recorded by requesting the participants isometric flexion of the knee in the prone position. The percentage of change of each variable was also analyzed.
