Immediate Neurophysiological Effects of PENS on Radial Nerve in Patients With Lateral Epicondylalgia

"The technique will be performed ultrasound-guided on the radial nerve, the places of the needle's insertions will be the following:~Needle will be placed at under the lateral intermuscular septum between the triceps brachii and brachialis, approximately 10cm superior to the lateral epicondyle Needle will be placed at the upper third of the forearm on the posterior interosseous nerve after passing the arcade of Frohse's~The percutaneous electrical stimulation will be realized with a transcutaneous electric nerve stimulation (TENS) current:~TENS Frequency 2 Hz TENS Pulse width - 250 microseconds Duration - 30 minutes. TENS Intensity - Increased at an intensity of visible motor response of the innervated musculature and maximal tolerable intensity.~Administration - One single session."
