Screening Diagnosis of Fall Risk After Stroke and Initial Intervention: A fNIRs Study

First Affiliated Hospital of Chongqing Medical University80 enrolled

Overview

This is a functional near infrared spectroscopy (fNIRs) study designed to screen for risk of falls after diagnosis of stroke and initial intervention.

This was an initial screening and preliminary intervention study. Each subject underwent two models of simultaneous fNIRs-EEG testing during the sit-to-stand process, the first without any intervention and the second based on biofeedback (EMG feedback) during the sit-to-stand process. Initial screening of fall risk in post-stroke patients was performed by comparing differences in brain activation and brain network connectivity between patients and healthy subjects. Preliminary validation the effectiveness of the EMG feedback-based sitting and standing training for post-stroke patients by comparing the differences of brain activation, brain network connectivity, and electromyographic changes during the sit-to-stand process in the two models.
