Brief summary (from the registry)
The goal of this pilot clinical trial is to evaluate whether the ultrasound-guided percutaneous peripheral nerve stimulation through a needle results in greater gains in strength and power compared to the administration of current through surface electrodes in patients undergoing strength and power assessments. The main questions it aims to answer are: Does percutaneous stimulation of the superior and inferior gluteal nerves using ultrasound-guided needles enhance strength and power more effectively than transcutaneous stimulation through electrodes? Is the effectiveness of current delivery significantly different between percutaneous and transcutaneous methods when assessed with a linear encoder in a standarized hip extension exercise? Participants will: Be randomized into two groups: one undergoing ultrasound-guided percutaneous stimulation of the gluteal nerves (experimental group) and the other undergoing transcutaneous stimulation through electrodes (control group). The same stimulation protocol at 10 Hz frequency with the maximum muscle contraction evoked without pain will be performed in both groups. Then, the participants will undergo strength and power assessment before and after therapy administration using a linear encoder in a hip extension exercise. Researchers will compare the experimental group to the control group to see if the method of current delivery (percutaneous vs. transcutaneous) has a significant impact on the gains in strength and power. This comparison is based on the hypothesis that percutaneous delivery of current, guided by ultrasound, is more effective than simply positioning a surface electrode for transcutaneous stimulation. The evaluation of strength and power will be performed through a linear encoder that measures peak strength and concentric power in each repetition, conducted by a blind operator unaware of the patients' group allocations.
