Preoperative MRI findings and functional outcome after selective dorsal rhizotomy in children with bilateral spasticity.

Purpose: To identify MRI characteristics that may predict the functional effect of selective dorsal rhizotomy (SDR) in children with bilateral spastic paresis.

Methods: We performed SDR in a group of 36 patients. The gross motor functioning measure-66 (GMFM-66) was applied before and after SDR.
