The mean MEP amplitudes recorded from the right FDI muscle during observation of index and static videos at high and low stimulation intensity in experiment 1.

<p>The MEP amplitudes are presented as <i>z</i>-scores (mean ± SE). Significant differences are indicated by asterisks (*<i>p</i> = 0.001).</p

Three different videos used in this study.

<p>Experiment 1 consisted of: (i) static hand and; (ii) index-finger movements. Experiment 2 consisted of: (i) static hand; (ii) index-finger movements and; (iii) little finger movements. One TMS pulse was delivered per video at either 2500 or 3500 ms after video onset.</p

The mean MEP amplitudes recorded from the participants' right FDI (left panel) and right ADM (right panel) muscles during observation of index, little, and static videos recorded from the FDI-OSP (white) and ADM-OSP (black) in experiment 2.

Individual participant's values for OSP and resting motor threshold percentage.

<p>The most common OSPs were 4 cm lateral and 1.5 cm anterior for FDI-OSP, and 4 cm lateral for ADM-OSP (all relative to Cz). The mean threshold value was 47% for FDI-OSP and 50% for ADM-OSP.</p

Mean (± SD) onset times (ms) for BP and NS’ components of the MRCP at week 1 and week 5, together with <i>p</i> values from the ANOVA analysis.

<p>A separate ANOVA was conducted for each component of the MRCP.</p
