Short-term physical training enhances mirror system activation to action observation

Figures & data

Table 1. A description of the unfamiliar hand actions performed in the videos and performed by the participants in the execution group.

Action 1	A ball is squeezed with all fingers on both hands and then rotated in the squeeze
Action 2	A desk bell is rung with the back of the hand
Action 3	The index finger and little finger move outwards, then the index and middle finger move in opposite way to the little and ring finger
Action 4	A ball is in-between both hands and rotated back and forth
Action 5	A pair of scissors are opened and closed with two little fingers
Action 6	A long toy is twirled between fingers on one hand

Figure 1. Percentage change from pre- to post-test for hand action observation and static hand observation in a) central alpha, b) occipital alpha, c) central beta, and d) occipital beta power for both training groups.

Figure 2. Mean action-static difference across the central electrodes in the post-training task for each training repetition frequency for both training groups in a) alpha and b) beta power. The square point represents the mean data for each training repetition frequency by training group and the circle point represents individual data.
