Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Tests: The non-dominant left arm was tested. The subjects performed a sequential point-to-point movement task on the graphics tablet. Initially, the participants were required to perform 3 sequences without errors to familiarize themselves with the setup, the task and the sequence. Then, they performed the pre-test which consisted of two blocks of 6 sequences, i.e. 12 sequences, with a 30 s break between blocks. Two min after starting the appropriate stimulation, they performed 2 blocks of 6 sequences (identical to the pre-test). After finishing the tDCS stimulation, the participants performed a post-test, which was also identical to the pre-test. The participants returned after 24 hours to perform a retention test, which was equivalent to the pre- and post-tests. Two outcome measures were used: movement time (s) and the reaction time (s) of the reaching movements.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
HD-tDCS 2 mA
Single session of 20-min HD-tDCS to the right primary motor cortex with an intensity of 2 mA. The session lasted approximately one hour. The participants returned after 24 hours to perform a retention test.
HD-tDCS 2 mA
anodal high definition transcranial direct current stimulation of the right primary motor cortex with an intensity of 2 mA
HD-tDCS 1.5 mA
Single session of 20-min HD-tDCS to the right primary motor cortex with an intensity of 1.5 mA. The session lasted approximately one hour. The participants returned after 24 hours to perform a retention test.
HD-tDCS 1.5 mA
anodal high definition transcranial direct current stimulation of the right primary motor cortex with an intensity of 1.5 mA
Control
Single session of 20-min of sham HD-tDCS. The session lasted approximately one hour. The participants returned after 24 hours to perform a retention test.
HD-tDCS sham
sham stimulation of the right primary motor cortex
