Abstract
Aim: This study aimed to examine whether motor imagery (MI) ability can be measured by use of the EEG Mu-rhythm. Second, this study provide the MI ability in children with unilateral Cerebral Palsy (uCP), compared to healthy peers, based on behavioral data (accuracy and reaction times (RTs), and the EEG Mu-rhythm. Method: RTs, accuracy, and EEG data from 8-12Hz were analyzed in 10 children with uCP and 13 typically developing children during the Hand Laterality Judgment task (HLJ) including a control condition in which no MI is expected. Res nits: All control, but only 7 out of 10 uCP children were able to perform the HLJ task. The control group showed no differences in Mu-suppression between experimental condition and control condition, and no effects within the experimental condition where found. The 7 uCP children performed worse than control children, with higher task failures for palm view stimuli than back view stimuli. Second, an overall view x rotation interaction was found with longer RTs in palm view stimuli for lateral rotated hands than medial rotated hands. Finally, they showed a rotation effect on the EEG Mu-rhythm with more Mu-suppression for lateral rotated hands than medial rotated hands. Conclusions: The present study proved to be inadequate to conclude whether EEG Mu-rhythm is a reliable measurement for MI, since the control condition was too strict and also elicited MI. In the uCP children, it can be concluded that if children with uCP are able to perform a HLJ task, they use a MI strategy to solve the task. Problems in this group seems to be in abstract thinking, and therefore they could only use a MI strategy and no mental rotation strategy to solve the task. Further research should add a mental rotation task in the uCP group, to study the deficits in mental rotation versus MI.
