Relationship between finger-tapping parameters and severity of medial temporal lobe atrophy.

The vertical and horizontal axes indicate the parameters of the finger-tapping movements and severity of medial temporal lobe atrophy. The SD of distance rate of velocity peak in extending movements of the non-dominant hand was r = 0.51 and p<0.001. The SD of distance rate of velocity peak in extending movements is defined as the SD of the value calculated as the position of the distance at which the velocity is maximal during the finger opening movement as a ratio to the amplitude.
