Association Between Spasticity and Functional Impairments During the First Year After Stroke in Korea : The KOSCO Study

The aim of the study was to investigate the correlation between
spasticity severity and functional outcomes during the first year after stroke.
DESIGN: The Korean Stroke Cohort for Functioning and Rehabilitation is a large,
multicenter, prospective cohort study of all patients with acute first-ever
stroke admitted to participating hospitals in nine Korean areas. To investigate
the correlation between spasticity severity and functional status measured by
using the Institutes of Health Stroke Scale (NIHSS), Modified Barthel Index
(MBI), Functional Independence Measurement (FIM), Fugl-Meyer Assessment (FMA),
Functional Ambulatory Category (FAC), modified Rankin scale (mRS), and American
Speech-Language Hearing Association National Outcome Measurement System
Swallowing Scale (ASHA-NOMS), data were analyzed at 3, 6, and 12 mos after the
occurrence of stroke. RESULTS: A total of 7359 stroke patients, 3056 were finally
included. Prevalence rates of spasticity in patients after stroke were 6.8% at 3
mos, 6.9% at 6 mos, and 7.6% at 12 mos. The scores of mRS and NIHSS were higher
and those of K-MBI, FIM, FMA, and ASHA-NOMS were lower in more severe spastic
patients, indicating poorer functional outcomes (P < 0.05). CONCLUSIONS: This
study demonstrated the coexistence of spasticity and poor functional outcome
during the first year after first-ever stroke patients.
