Effectiveness of Eco-guided Neuromodulation of the Femoral Nerve on the Performance of Amateur Athletes. Randomized Controlled Crossover Clinical Trial
This randomized crossover study aims to evaluate whether different percutaneous electrical nerve stimulation (PENS) protocols produce changes in neuromuscular performance in healthy adults.
PENS involves the ultrasound-guided application of an electrical current through a needle to modulate motor neuron excitability.
Each participant will undergo five intervention sessions: (1) a long-term potentiation (LTP)-based protocol with impulse trains, (2) a 10 Hz protocol with 10 s stimulation and 10 s rest repeated ten times, (3) a 5-55 protocol with 100 Hz stimulation for 5 s followed by 55 s rest repeated five times, (4) a high-intensity burst (HIB) protocol applied at a high current intensity close to 1000 mA and repeated three times, and (5) a placebo condition.
All interventions will be applied bilaterally by an experienced physiotherapist under ultrasound guidance, with a two-week washout between sessions.
The objective of this trial is to assess whether these stimulation patterns produce measurable changes in squat execution velocity, jump performance, and quadriceps strength.
The findings may help identify the most effective stimulation strategy for enhancing neuromuscular performance.

Intervention / Traitement |
|---|---|
|
Expérimental: Theta Burst Protocol
The intervention consists of the bilateral, ultrasound-guided insertion of a needle for percutaneous electrical nerve stimulation (PENS), following a theta-burst pattern designed to produce long-term potentiation-like effects.
An asymmetric biphasic compensated current with a rectangular positive phase and a triangular negative phase is applied at a frequency of 100 Hz for 5 seconds, followed by 55 seconds of rest, repeated five times.
The pulse width is 240 µs, and the intensity is maintained above the motor threshold and below the pain threshold.

Expérimental: 10-10-10 Protocol
The intervention consists of the bilateral, ultrasound-guided insertion of a needle for percutaneous electrical nerve stimulation (PENS).
An asymmetric biphasic compensated current is applied, with a rectangular positive phase and a triangular negative phase, at a frequency of 10 Hz, pulse width of 240 µs, and an intensity above the motor threshold and below the pain threshold.
Each stimulation period lasts 10 seconds, followed by 10 seconds of rest, repeated ten times.

Expérimental: HIB Protocol (High-Intensity Burst)
Ultrasound-guided PENS protocol consisting of high-intensity bursts applied bilaterally at a current intensity close to 1000 mA, repeated three times.
The intensity is set individually, approaching but not exceeding the participant's tolerance threshold.
