Demographic data of each individual of the group of patients.

<p>For each participant, the following data was obtained at the time the patient began the study: The age (years), months since the stroke, the Medical Research Council (MRC) score, the location of the lesion and the Barthel Index.</p

Summary of the kinematic parameter for the patients' group (PG) and control group (CG).

<p>Bars represent the mean of frequency (FREQ), number of inversions of velocity (NIV) and the average maximum velocity (Max Vel) for finger tapping (FT), hand tapping (HT) and forearm pronation-supination (PS). Error bars represent the standard deviation of the mean (SEM). Significant differences after training in the MG are indicated (* p<.05, ** p<.01).</p

Correlation between changes on the position of the CoG in the mediolateral edge and changes on the number of inversion of velocity (NIV) for hand tapping (HT) from subjects in PG.

<p>Rounded points were considered outlier values after corresponding test and were excluded from the sample.</p

Summary of the plastic changes observed with the cortical maps.

<p>(A) Displacement of the center of gravity (CoG) across time for the affected and unaffected hemisphere in PG. The origin of each arrow represents the baseline coordinates of the CoG. Arrowheads represent the position of the CoG at evaluation 2. Each arrow is colored differently, corresponding to each subject from PG. (B) Displacement of the medial coordinate of the center of gravity (CoGx) of motor mapping representation through time. In the affected hemisphere (left), almost all patients showed a displacement on the mediolateral edge of the CoG to more temporal regions.</p

Example of performance of fast diadochokinetic finger.

<p>Detail of the signal recorded from one marker with the 3D movement-analyzer during finger and hand tapping movements of the affected hand of one representative patient (A) and one control subject (B). The marker was attached on the index finger (finger tapping) and from methacarpophalangeal joint (hand tapping). Time courses of the displacement in cm measured in both evaluations are displayed.</p

Results of ANOVA analysis of each dependent variable concerning diadochokinetic movements performed with the contralateral hand.

<p>Units of each dependent variable are also shown. Notes: FREQ = frequency; VMAX = maximal velocity; NIV = number of inversion of velocity; FT = finger tapping; HT = hand tapping; PS = pronation-supination; deg = degree; s = second.</p

Results of ANOVA analysis of each dependent variable concerning electrophysiological measurements obtained after the stimulation of each hemisphere (affected and unaffected) (* <i>p</i><.05; ⁺.05<<i>p</i><.1; n.s. not significant).

<p>Notes: MEP = peak-to-peak amplitude of the motor evoked potential; RMT = resting motor threshold; AMT = active motor threshold; CoG_x = mediolateral coordinate of the center of gravity; CoG_y = anteroposterior coordinate of the center of gravity; CSP = cortical silent period; µV = microvolts; ms = milliseconds; cm² = squared centimeters.</p
