| Abstract: | Left hemisphere injury can cause right spastic arm paralysis and aphasia, and recovery of both motor and language functions shares similar compensatory mechanisms and processes. Contralateral cervical seventh cross transfer (CC7) surgery can provide motor recovery for spastic arm paralysis by triggering interhemispheric plasticity, and self‐reports from patients indicate spontaneous improvement in language function but still need to be verified. To explore the improvements in motor and language function after CC7 surgery, we performed this prospective observational cohort study. The Upper Extremity part of Fugl‐Meyer scale (UEFM) and Modified Ashworth Scale were used to evaluate motor function, and Aphasia Quotient calculated by Mandarin version of the Western Aphasia Battery (WAB‐AQ, larger score indicates better language function) was assessed for language function. In 20 patients included, the average scores of UEFM increased by.40 and 3.70 points from baseline to 1‐week and 6‐month post‐surgery, respectively. The spasticity of the elbow and fingers decreased significantly at 1‐week post‐surgery, although partially recurred at 6‐month follow‐up. The average scores of WAB‐AQ were increased by 9.14 and 10.69 points at 1‐week and 6‐month post‐surgery (P <.001 for both), respectively. Post‐surgical fMRI scans revealed increased activity in the bilateral hemispheres related to language centrals, including the right precentral cortex and right gyrus rectus. These findings suggest that CC7 surgery not only enhances motor function but may also improve the aphasia quotient in patients with right arm paralysis and aphasia due to left hemisphere injuries.
