Descrizione dettagliata
This project is also designed to investigate the optimal application timing of tDCS in combination with MT in patients with subacute and chronic stroke.
Patients with subacute and chronic stroke will be recruited and randomized into one of the 3 groups: sequentially apply tDCS and MT group (SEQ), apply tDCS concurrently with MT group (CON), and MT with sham tDCS group (SHAM).
All participants will receive 40 minutes of MT followed by 30 minutes of functional task training.
For the participants in the SEQ group, 20 minutes of tDCS will be applied prior to MT, while tDCS will be applied concurrently with MT for the first 20 minutes in the CON group.
As for the SHAM group, tDCS electrodes will be placed on the scalp without actual current output.
The interventions will be carried out 90 minutes per day, 5 days per week, for 4 weeks.
Behavioral outcomes will be assessed by blinded evaluators before, after, and 3 months post intervention.
To study the possible interaction of treatment group and time of outcome evaluations, group (SEQ vs. CON vs. SHAM groups) × time (pretest vs. posttest vs. follow-up) repeated measures ANOVA will be performed.
Additionally, the partial eta square (η2) will be calculated to determine the effect size of interest.

Sperimentale: sequentially apply tDCS and MT
The participants in the SEQ group will first receive a-tDCS applied over M1 lesioned without any active arm practice for 20 minutes.
For the following 20 minutes, the participants will receive the MT, while the electrodes will be remained on the scalp without stimulation (sham tDCS).
Then the electrodes will be removed from the scalp, and the participants will continue another 20 minutes of MT without tDCS.
The treatment session will be ended with 30 minutes of functional task practice.

In addition to MAL, the ActiGraph GX3 accelerometers (ActiGraph, Shalimar, FL, USA) will be used to quantitatively assess the amount of arm use in the participants' home settings.The actigraphy will be placed on bilateral wrist for 3 consecutive days before and after the 1-month intervention.
The participants will carry the actigraphy all day except for activities that involve water, such as swimming or bathing.
Using the actigraphy, investigators will be able to record and calculate the number of hand movements per minute, and the data will be analyzed with the MAHUFFE software (http://www.mrc-epid.cam.ac.uk/).
