Echo-guided Percutaneous Electrical Nerve Stimulation of the Femoral Nerve

Efficacy of Echo-guided Percutaneous Electrical Nerve Stimulation of the Femoral Nerve on Explosive Strength and Metabolic Response in Healthy Subjects. A Randomised Clinical Trial.

Introduction. Variables such as pain and strength can be modified in the short and medium term by the application of currents. The percutaneous form of percutaneous needle-guided acupuncture can eliminate the impedance of the surrounding tissues that limit the optimal diffusion of the current to the target tissue. It is necessary to objectify the metabolic response of this technique and its effects in terms of strength and metabolic response.

Objective. To evaluate the safety and efficacy, in acute and subacute phases, of percutaneous electrical nerve stimulation in healthy subjects.

Method. Single-blind randomised clinical study. Thirty-two subjects will be recruited and randomised to the experimental and control groups. The intervention in the experimental group will consist of a percutaneous percutaneous electrical nerve stimulation of the femoral nerve, while in the control group the same intervention will be performed without increasing the intensity of the current. The primary variable will be vertical jump height (My Jump® iOS app) and the secondary variable will be skin temperature (Hikmicro M60 model Hangzhou).

Inclusion Criteria:

• Persons aged 18 and 24.

• Who sign the informed consent document.

Exclusion Criteria:

• Medical diagnosis of chronic systemic diseases or diseases that may interfere with thermographic imaging (rheumatoid arthritis, fibromyalgia, deep vein thrombosis, etc.).
• Having undergone lower limb surgery in the 24 months prior to the study.
• Intake of drugs that may influence the thermographic response (antipyretics, non-steroidal anti-inflammatory drugs, topical solutions on the area to be studied, etc.).
• People with nickel allergy or belonephobia (needle phobia).
