Abstract

Background. Spasticity is prevalent and disabling in persons with multiple sclerosis (MS), and the development of the Multiple Sclerosis Spasticity Scale-88 (MSSS-88) provides an opportunity for examining the perceived impact of spasticity and its association with gait in this population. Purpose. This study examined the association between the perceived impact of spasticity and spatio-temporal parameters of gait in persons with MS. Methods. The sample included 44 adults with MS who completed the MSSS-88 and 4 walking trials on a 26-foot GAITRiteTM electronic walkway for measurement of spatio-temporal components of gait including velocity, cadence, base of support, step time, single support, double support, and swing phase. Results. The overall MSSS-88 score was significantly associated with velocity ( π‘Ÿ = βˆ’ 0 . 3 7 1 ), cadence ( π‘Ÿ = βˆ’ 0 . 3 0 6 ), base of support ( π‘Ÿ = 0 . 3 5 7 ), step time ( π‘Ÿ = 0 . 3 0 5 ), single leg support ( π‘Ÿ = βˆ’ 0 . 3 8 8 ), double leg support ( π‘Ÿ = 0 . 3 7 9 ), and swing phase ( π‘Ÿ = βˆ’ 0 . 3 8 6 ). Conclusions. The perceived impact of spasticity coincides with alterations of the spatio-temporal parameters of gait in MS. This indicates that subsequent interventions might target a decrease in spasticity or its perceived impact as an approach for improving mobility in MS.
