Scatter plot of the Fugl - Meyer Upper Extremity scores before and after treatment. Fitted models in the RFVE and ULC groups are displayed in dashed and dotted line, respectively. The plot shows the better score at F-M UE scale after RFVE compared with ULC therapy, adjusted for the severity of pre treatment motor impairment. Empty circle (о) represents individual F-M UE score of the RFVE patients group, cross symbol (+) represents individual F-M UE score of the ULC patients group.
