Effects of dual task on gait velocity and cadence in cerebral palsied children with spastic hemiparesis or diparesis.

Gait is generally considered an automated process with little or no cognitive input. In most individuals with Cerebral Palsy (CP), walking restrictions may accompany during childhood and adolescence. The aim of this study was to determine the effects of dual task on Gait Velocity (GV) and Cadence (C) in Cerebral Palsied Children with Spastic Hemiparesis or Diparesis (CPCSHD). Fourteen boys, seven girls' spastic hemiparesis children (mean age: 13.33 ± 3.79 years) and twelve girls, nine boys' diparesis children (mean age: 14.44 ± 3.24 years) were included in the study. Forty-two CPCSHD having level 1 or 2 according to the Gross Motor Function Classification System (GMFCS) were included in this comparative study. GV was calculated using a chronometer for a 10-m walk on the ground with shoes. Cadence was calculated accounting the number of steps during 1-min walk. Both GV and C tests were performed by each participant with single task first. After the single task, all were asked to perform the dual task carrying a plastic water-filled bottle. There were no significant differences between the hemiparesis and diparesis in terms of demographics data. When children with hemiparesis and diparesis compare each other, no significant differences were found in terms of all the outcome parameters. The results obtained from this study indicate that walking speed and cadence decrease during a dual motor task in CPCSHD (p > 0.05). When hemiparesis and diparesis groups were compared, no difference was found between the groups.
