Outcome
Type Measure Description Time frame Safety issue
Primary Correlation coefficient between strength of connection and the Fugl-Meyer Assessment score Strength of connection is obtained by calculating a correlation coefficient between time courses of both regions in fMRI data. Through study completion, an average of 1 year
Primary Correlation coefficient between the FA value of a tract and the Fugl-Meyer Assessment score FA value is obtained by assessing a diffusion anisotropy of a specific tract in DTI data. Through study completion, an average of 1 year
