Improvement and Neuroplasticity after Combined Rehabilitation to Forced Grasping

Figure 8

Three-dimensional maps of hemodynamic responses (changes in the oxy-Hb concentration) in the brain while the patient performed pinching with the left hand under continuous electrical stimulation of the extensor side of the forearm before BTX-A treatment (a) and after BTX-A treatment (b). There was activation in both SMC and ipsilesional PFC before BTX-A treatment, and the activation area was more localized at the ipsilesional SMC after BTX-A treatment.
