Early Postural Stability Changes in Patients Undergoing Correction of Spinal Deformity: A Prospective, Controlled Pilot Study.

Keister, Alexander BS a,b; Grossbach, Andrew MD b; Toop, Nathaniel MD b; Mallory, Noah BS a,b; Gibbs, David BS a,b; Xu, David MD b; Viljoen, Stephanus MD b

doi : 10.1097/BRS.0000000000004527

AB Background Context. Adult spinal deformity (ASD) is a prevalent condition often requiring surgical intervention. Improved outcomes among ASD patients have been shown to correlate with postoperative spinopelvic parameters, yet little is currently known about the role of postural stability and balance assessment for ASD patients.
