Percutaneous Neuromodulation on the Anterior Pain Knee

Anterior knee pain (AKP) is one of the most frequent pathologies of the lower limb, in young and adult subjects. In the field of Physiotherapy, ultrasound-guided Percutaneous Neuromodulation (PNM) is defined as the application through a needle with ultrasound guidance of an electrical current at low or medium frequency, seeking a sensitive and / or motor response of a peripheral nerve in some point of its trajectory, or of a muscle in a motor point, with a therapeutic objective. The objective of this study is to analyze that the effect of PNM on the femoral nerve produces statistically significant changes in pain, joint range and knee functionality in patients with chronic AKP. Thirty subjects will be recruited, which will be divided into 2 groups: group 1 to which PNM will be applied to the femoral nerve of the pain knee; and group 2 to which PNM will be applied to the femoral nerve of the non-pain knee. The PNM intervention with NMP will consist in the single application of an asymmetric rectangular biphasic current (250 microseconds, 10 Hz)
