简要总结
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.
