Primary outcomePrimary: Difference of Maximum Grip Strength — 03; 0; -02 Kilograms (Kg)
Summary
The design aims to investigate the value of direct current, specifically the polar effects this has, and its influence on neuromuscular changes described in the literature. This research proposal seeks to assess the influence of application anode and cathode pole in muscle strength when testing handgrip dynamometry by healthy subjects. The study will evaluate changes in muscle strength when performing a manual dynamometer test in a group exposed to the application of cathode, another exposed to the application of anode, compared with a control that will not receive the intervention will be evaluated. Subsequently the investigators proceed to compare the maximum force obtained from the dynamometry test in each of groups and between the groups .
