Ultrasound-guided Percutaneous Electrical Stimulation for Gluteus Muscle Dysfunction After Low Back Pain Episode

"Valera \& Minaya protocol:~US-guided PNM with the conventional frequency of the Valera Minaya protocol, with localised location on the peripheral nerve. Stimulation of the upper gluteal nerve and lower gluteal nerve will be performed, with 10 stimulations, with 10 seconds of stimulation and 10 seconds of rest, at a frequency of 10 Hz, with a pulse amplitude of 250 μs, and of maximum intensity tolerable by the patient that causes an exacerbated muscle contraction.~The specific device used will be an electric needle stimulator, AS Super 4 Digital, Schwa-medico Holistic Health, Ehringshausen, Germany."

"High-frequency US-guided PNM with localised peripheral nerve location. Ten 10-second stimulations of the upper gluteal nerve and lower gluteal nerve will be performed, with frequency sweeps of 20Hz -100Hz with a pulse amplitude of 250 μs, and of maximum intensity tolerable by the patient that causes an exacerbated muscle contraction, with 10 seconds of rest between each stimulation.~The specific device used will be an electric needle stimulator, AS Super 4 Digital, Schwa-medico Holistic Health, Ehringshausen, Germany."
