Fig. (3) fMRI with MR_CHIROD in a 63-year old chronic stroke patients, four years after his MCA stroke. A, left: Patient performing the motor paradigm halfway through training. B, right: Patient performance after training. The patient squeezed the MR_CHIROD at 45%, 60%, and 75% of maximum grip force. Activation threshold P < 0.05, corrected; activation maps are superimposed on patient T1-weighted anatomical image. SMC activation is the larger arrow; SMA activation is the smaller arrow.
