Abstract

The aim of this study was to determine the effect of action observational physical training (AOPT) on manual dexterity and corticomotor facilitation in stroke patients. Ten hemiparetic patients participated in this study. Each subject was asked to participate the three conditions; base condition (Base), physical training (PT), AOPT. Participants were asked to observe the action in the video that a therapist moved the blocks during the AOPT conditions. Corticomotor facilitation was determined in three conditions by monitoring changes in the amplitude of motor-evoked potentials (MEPs) elicited in hand muscles by transcranial magnetic stimulation. MEP responses were measured from the first dorsal interosseous after participants attended to three conditions. For the manual dexterity, Box and Block test (BBT) was used. The results of present study were summarized as follows: MEPs amplitude significantly tended to be larger than PT and Base condition. The scores of BBT in the AOPT condition were also significantly larger than other conditions. In conclusion, this finding of present study indicates that physical training for observation of an action is beneficial for enhancing a dexterity of paretic arm in stroke patients.
