Brief 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 .

Arm Intervention/treatment
Experimental: Cathode Stimulation
Group that is involved with the (black) negative electrode seeking the polar effect of nervous increased excitability and conductivity with the current application.
Device: Cathode stimulation
Electrical stimulation through the cathode or negative pole, in which a peripheral nerve will be subject to the passage of a direct current seeking increased excitability and conductivity during the passage of current.
Other Name: Cathode Polar effect

Experimental: Anode Stimulation
Group that is involved with the (red) positive electrode seeking the polar effect of nervous excitability and conductivity decreased with the current application.
Device: Anode stimulation
Electrical stimulation through the anode or positive pole, in which a peripheral rib will be subjected to the passage of a direct current seeking to reduce excitability and conductivity during the passage of current.
Other Name: Anode Polar effect

Placebo Comparator: Control
Group that will be placed electrotherapy without operation, but only installation. Patients in this group will see the team work but it will not be delivering current.
Device: Placebo
Current application without the actual electric conduction to the person occurs. This will be achieved by adjusting parameters while installing another channel and not one that is working.
Other Name: Non intervention




Primary Outcome Measures :
  1. Difference of Maximum Grip Strength [ Time Frame: Baseline and 1 hours later (1 session of treatment), assessed as up to 1 month. ]
    The difference in maximum grip strength is that value in kilograms obtained between the best score of the first three gripping attempts made before the intervention compared to the best result obtained from the three attempts after the intervention. The maximum force difference will express the force changes before and after the participants are exposed to one of the treatments.


Secondary Outcome Measures :
  1. Difference of Maximum Grip Strength for Males [ Time Frame: Baseline and 1 hours later (1 session of treatment), assessed as up to 1 month. ]
    The difference in maximum grip strength for males is that value in kilograms obtained between the best score of the first three gripping attempts made before the intervention compared to the best result obtained from the three attempts after the intervention considering only the men of each group. Maximum force difference will express the force changes before and after the participants are exposed to one of the treatments.

  2. Difference of Maximum Grip Strength for Females [ Time Frame: Baseline and 1 hours later (1 session of treatment), assessed as up to 1 month. ]
    The difference in maximum grip strength for females is that value in kilograms obtained between the best score of the first three gripping attempts made before the intervention compared to the best result obtained from the three attempts after the intervention considering only the women of each group. Maximum force difference will express the force changes before and after the participants are exposed to one of the treatments.
