Preliminary investigation of feasibility and test-retest reliability of a novel
electroencephalography (EEG)-based brain mapping system in healthy children and
children with cerebral palsy (CP). DESIGN: Correlation statistics. SETTING: University brain mapping and neurorehabilitation laboratory. PARTICIPANTS: A
convenience sample of children (N=12; 5 healthy children, mean +/- SD,
12.6+/-0.89y; 7 children with CP, mean +/- SD, 9.71+/-1.1y) participated in the
study. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Mu band (8-12Hz)
power values in event-related spectral perturbation maps during reach and grasp
hand movements were repeatedly measured on 2 separate occasions (2h apart).
Intraclass correlation coefficient (ICC(1,2)) tests were computed to determine
test-retest reliability at the standard level of significance
(P<.004). In
addition, the feasibility of the system was determined by evaluating potential
differences in the cortical activation areas obtained from topographical maps
during actual reach and grasp motor tasks between healthy children and children
with CP. RESULTS: The test-retest reliability results showed excellent
reliability between the repeated measures, ranging from .93 (P=.000) to .99
(P=.000). Our EEG brain mapping system was capable of distinguishing differences
in the cortical activity power (mu band power spectra) between healthy children
and children with CP. CONCLUSIONS: To our knowledge, this study is the first
evidence demonstrating the feasibility and reliability of the EEG brain mapping
system. Clinically, this system provides important insights into neuroplasticity
associated with motor recovery after treatment and can also be used as real-time
neurofeedback or noninvasive neuromodulation in the course of neurologic
rehabilitation.
