Stroke Clinical Trial - Brain Connectivity as a Biomarker of Response to

Status Not yet recruiting

Clinical Trial Summary

A randomized, double-blind, sham-controlled clinical trial will be conducted with 30 people with stroke, recruited at a referral hospital in João Pessoa. After recruitment they will be randomized into two groups: Group 1 - active stimulation and group - 2 sham stimulation. Participants will receive 10 sessions of ETCC, for 20 minutes, on alternate days (3 times a week), where the electrodes will be positioned over the primary motor cortex. 3 minutes of EEG at rest will be taken from each participant, and they will be instructed not to be actively involved in any cognitive or mental activity. In the first and last meetings, evaluations will be carried out, the outcomes evaluated will be: motor function, quality of life and functional connectivity.

Clinical Trial Description

Previous studies analyzed by systematic reviews suggest that the effects of ETCC may vary between subjects, where some stroke patients may not receive any additional benefits from therapy. Thus, it is necessary to use a biomarker that manages to elect those who will possibly benefit from the electric current. Therefore, the objective of this study is to investigate whether the EEG measures of functional connectivity of the target network of the stimulation are associated with the response to ipsilesional anodic ETCC in patients with stroke in the late subacute phase. as well as to observe if these findings can be associated with a clinical improvement of the patient. For that, a randomized, double-blind, sham-controlled clinical trial will be carried out with 30 people with stroke, recruited at a referral hospital in joão Pessoa. After recruitment they will be randomized into two groups: Group 1 - active stimulation and group - 2 sham stimulation. Participants will receive 10 sessions of ETCC, for 20 minutes, on alternate days (3 times a week), where the electrodes will be positioned over the primary motor cortex. 3 minutes of EEG at rest will be taken from each participant (Eyes open and eyes closed), and they will be instructed not to be actively involved in any cognitive or mental activity. In the first and last meetings, evaluations will be carried out, the outcomes assessed will be: motor function, quality of life and functional connectivity. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
