Pearson correlation is shown as CORR (r) and Feature X correlation as fx, both unitless. The table displays per-task correlation averages for all subjects for each task. Note that the Dyno task does not have an fx value, as fx requires joint angle changes, which were fixed in this task. Dyno also includes preliminary sessions (n=10), while main cohort for all tasks has n=6. These correlation values represent the comparison of AA voltage values with ID moments as calculated through OpenSim.
