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

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 beta-band activity decreased posttraining. Therefore, the participants' FOG and beta-band activity decreased. Rhythmic finger movement training shows potential as an effective intervention for FOG; more study is needed.
