Effect of Rhythmic Finger Movement Training on Freezing of Gait and Electroencephalography Activity in People With Parkinson Disease

Abstract

We examined the effects of rhythmic finger movement training on freezing of gait (FOG) and electroencephalography (EEG) activity in 3 participants with Parkinson disease (PD). Participants underwent 3 minutes' rhythmic finger movement training twice daily for 4 weeks. We measured walking condition acceleration and EEG activity with and without a doorway, pre- and postintervention. Freezing index (FI), indicating FOG, was calculated from acceleration data. The high walking condition FI observed pretraining with a doorway decreased posttraining. The high pretraining frontal β-band activity decreased posttraining. Therefore, the participants' FOG and β-band activity decreased. Rhythmic finger movement training shows potential as an effective intervention for FOG; more study is needed.
