Abstract
We assess the effects of EEG biofeedback training on levodopa-induced dyskinesia (LID) in patients with Parkinson's disease (PD) using a sham feedback controlled study design. Nine subjects were randomized into either a treatment group or control group and underwent 24 sessions of either active feedback training or sham feedback. The training protocol aimed at increasing 8–15 Hz activity while inhibiting excess 4–8 Hz and 23–34 Hz activity at the C3-C4 derivation. There were no statistically significant differences baseline to post-active neurofeedback training as compared to sham feedback training in primary outcome measures assessing change in dyskinesia severity, nor in secondary outcome measures assessing change in clinical features of PD. Nonsignificant trends were observed in subjects’ PD home diaries indicating a decrease in the severity of motor fluctuations. Baseline to post-training comparisons of secondary outcome measures in quantitative EEG analysis showed significant interaction effects with...
