Abstract

|
Objective: Contralateral seventh cervical nerve transfer (contralateral C7 transfer) is a newly attempted method to restore upper extremity motor function in the patients with spastic arm paralysis. The aim of this study was to investigate the effects of contralateral C7 transfer on upper extremity motor function in the patients with spastic hemiplegia after stroke.
Design: A retrospective cohort study.
Methods: Thirty-four patients with spastic hemiplegia after stroke was investigated. All patients registered between January 2020 and February 2021. The subjects were assessed on upper extremity motor function, cognition, and spasticity before and after contralateral C7 transfer. The upper extremity motor function was measured using the Fugl-Meyer upper extremity scale and box & block test. The cognition and spasticity were assessed by Korean version mini mental state examination (K-MMSE) and modified Ashworth scale from baseline to 8 weeks after the surgery.
Results: The Fugl-Meyer upper extremity scale and modified Ashworth scale were significantly improved after contralateral C7 transfer (p<0.05). However, box & block test and K-MMSE were no significant changes after the surgery (p＞0.05).
Conclusions: This study suggested that the contralateral C7 transfer was a feasible and practical approach to improve upper extremity motor function in the patients with spastic hemiplegia after stroke, but further study is required to identify the long-term effects after the contralateral C7 transfer.
