Ultrasound-guided Percutaneous Neuromodulation in Anterior Cruciate Reconstruction

Ultrasound guided percutaneous neuromodulation in femoral nerve. Patients were placed in supine lying with the anterior aspect of the hip uncovered. The intervention consisted of the application of a biphasic square wave electric current, with a frequency of 2 Hz, a phase duration of 250μs, and a maximum tolerable intensity to cause an exacerbated muscle contraction for 15minutes in total
