Background: Spasticity is a common and disabling problem in multiple sclerosis (MS), but its effect in other CNS inflammatory demyelinating diseases (CNSIDDs), such as neuromyelitis optica spectrum disorder (NMOSD) is not widely studied. This study aims to compare subjective and objective measurements of spasticity in NMOSD patients and determine associated factors.
Methods: A prospective cross-sectional study was performed on CNSIDD patients attending the Multiple Sclerosis and Related Disorders Clinic at Siriraj Hospital, a tertiary hospital in Thailand, from June to November 2020 was performed.
