Direct Current Cathode and Anode Effects and Changes in Handgrip Strength. Evaluation Through a Dynamometer Test
Chile150 participantsStarted 2015-09
Plain-language 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 .

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
