After 15 sessions of treatment , a significant reduction was determined in the composite spasticity score ( 2.75 ; 99 % CI , 1.31-4 .19 ; P < .001 ) , the muscle tone score ( 1.75 ; 99 % CI , 0.16-3 .34 ; P = .006 ) , and the ankle clonus score ( 0.75 ; 99 % CI , 0.18-1 .32 ; P = .003 ) in the experimental group , whereas none of the outcome variables revealed a significant reduction in the control group .
