Effects of Ascending and Descending Direct Current on the Handgrip Strength
Chile87 participantsStarted 2017-06-26
Plain-language summary
Electrical stimulation currently has a wide range of clinical applications, being used for activities such as strengthening, pain control, edema management, or inflammation control after injury or surgery. One of the classic forms of electrotherapy is the Direct current (galvanic current), which stands out for its unique effects (polar and interpolar effects) and that are not achieved with other modalities of electrotherapy. Within these effects those activators or suppressors of nervous system activity are described. One of the applications of direct current is to produce sedation or excitation on the nervous system through longitudinal applications (longitudinal galvanization). This application technique is known as the upstream or downstream effect of the direct current or "Leduc Effect", in which it is postulated that an ascending type longitudinal galvanization has excitation effects of the central and / or peripheral nervous system. The study will evaluate the influence of the upward and downward direct current effect when performing a manual dynamometer test while monitoring by miofeedback in college students.

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.
