Selective Dorsal Rhizotomy: Patient Demographics and Postoperative Physical Therapy.

BACKGROUND

Selective dorsal rhizotomy (SDR) is a surgical procedure that permanently alters lower extremity spasticity, common in children with spastic cerebral palsy (CP). Intensive postoperative physical therapy (PT) is recommended following SDR. The first purpose of this study is to describe and compare patient demographics between children who received SDR and the population of children with CP at one institution. The second purpose of this study is to compare the completed dose of postoperative PT with the clinically recommended dose for a subset of ambulatory children who underwent SDR.

METHODS

This retrospective, observational study included 60 children with spastic CP following SDR. A subset (n = 12 ambulatory children) was included to describe the dose of postoperative PT. Information gathered from electronic medical records included age at the time of SDR, sex, Gross Motor Function Classification System level, anatomic distribution, race, county-level habitancy, health insurance provider, timed current procedural terminology codes, and location for postoperative PT encounters within a single institution.

RESULTS

Black or African American children (P = 0.002), children living in large central metro areas (P = 0.033), and children with public insurance (P ≤ 0.001) were significantly less likely to receive SDR. Children undergoing SDR do not achieve the recommended dose of PT after hospital discharge.

CONCLUSION

SDR is not equally accessed by patient populations, and postoperative PT frequency is below current recommendations throughout the rehabilitation process. Future studies need to investigate why these disparities exist and what prevents children from meeting the clinically recommended dose of postoperative PT after SDR.
