Comparison of Foot Pressure Variables in Blind and Healthy Participants with Open and Closed Eyes While Walking
Introduction: Measurement of foot pressure variables can be used to assess the loads to which the human body is subjected in normal activities, like walking, or in more demanding situations such as sports. The purpose of this study was to compare the foot pressure variables in blind and healthy individuals with open and closed eyes during walking. Methods: The present study was a quasi-experim...
متن کاملReliability comparison of spontaneous brain activities between BOLD and CBF contrasts in eyes-open and eyes-closed resting states
Blood oxygenation level dependent (BOLD) and arterial spin labeling (ASL) are two predominant resting-state fMRI techniques in mapping spontaneous brain activities. At single voxel level, cerebral blood flow (CBF) measured by ASL and amplitude of low frequency fluctuations (ALFF) of BOLD have been recognized as useful indices to characterize brain function in health and disease. However, no stu...
متن کاملAmplitude differences in high-frequency fMRI signals between eyes open and eyes closed resting states
Recent studies employing rapid sampling techniques have demonstrated that the resting state fMRI (rs-fMRI) signal exhibits synchronized activities at frequencies much higher than the conventional frequency range (<0.1 Hz). However, little work has investigated the changes in the high-frequency fluctuations between different resting states. Here, we acquired rs-fMRI data at a high sampling rate ...

متن کاملThe Difference of Brain Functional Connectivity between Eyes-Closed and Eyes-Open Using Graph Theoretical Analysis
To study the differences in functional brain networks between eyes-closed (EC) and eyes-open (EO) at resting state, electroencephalographic (EEG) activity was recorded in 21 normal adults during EC and EO states. The synchronization likelihood (SL) was applied to measure correlations between all pairwise EEG channels, and then the SL matrices were converted to graphs by thresholding. Graphs wer...
