There were 193 males and 134 females
with mean age 62.2+12.1 years old (min 21, max 93)
participating in the present study. A hundred and two
patients had spasticity of both elbow and knee flexors.
Thirty-four patients had spasticity of either elbow or
knee flexors. Therefore, the total prevalence of
poststroke spasticity was 41.6% (95% CI = 36.4-47.0).
Focusing on the single joint, the prevalences of
spasticity of elbow and knee flexors were 4.9% and
5.5% respectively. (Table 1). Among those who
developed spasticity, it could be elicited on admission
in most patients. The degree of spasticity according
to the MAS score was grade 1 for the majority. The
number of patients who had spasticity with MAS
grade 1+ and 2 were quite close in value. Notably,
significant spasticity which was defined as the muscle
tone abnormalities with MAS grade 3 and 4, was
very few. Only one patient had spasticity with MAS
grade 3 and none reported spasticity with MAS
grade 4 (Table 2).
