Clinical Trial Summary

Low-frequency percutaneous electrical stimulation is the application of an electrical current of <1000Hz through acupuncture needles located on the epineurium of the peripheral nervous system. The hypothesis is that by placing the electrode, needle, closer to the nerve, a greater stimulation of the same will be achieved, thus being able to obtain greater effects. The goal is to determine if this technique has any effect on grip strength in the short term.


Description:

Single-blind randomized clinical trial of n = 12 healthy subjects. 4 assessments of the grip strength of the non-dominant hand will be made using a digital dynamometer, by a blinded investigator. A V0-pre-intervention, a V1-post-intervention, a V2 at 24 hours and a V3 at 10 days after the intervention. Subjects will be randomly assigned by EPIDAT 3.1, to an experimental group or a control group, with n = 6 each group. In the experimental group, an ultrasound-guided percutaneous electrical stimulation will be performed. With a pointer, a symmetrical biphasic low-frequency current of 10 Hz and 240 microseconds will be applied to the median nerve and ulnar nerve, until reaching the excitomotor threshold, with applications of 10 seconds and rests of 5 seconds until reaching a stimulation of 1 minute. total over each nerve. In the control group, the same invasive procedure will be performed, but no type of electrical stimulation will be applied. Statistical analysis will be performed by another blinded assessor, using IBM SPSS Statistics 24. A two-factor ANOVA (intervention-time) with Bonferroni correction will be performed.
