Abstract
For individuals with Cerebral Palsy (CP), functional reaching is key to independence.
Previous research indicates benefits for multisensory input, while presently it is unknown how
sensory input occurs during goal-directed movements in CP. This study considered the influence of an auditory stimulus during the planning or execution phases of a goal-directed reach task.
Three conditions were presented: No Sound, Sound:Before, and Sound:During. Adult
participants (10 CP; 10 TD) reached from a home switch to one of two targets. Reaction time
analyses demonstrated a significant main effect for condition, with decreased RT in the SB
conditions for both groups. Analysis of variable error revealed significant main effects for group and condition; the CP group executed more consistent movements in both conditions. Analysis of ttPV/movement time revealed a significant interaction, indicating the CP group engaged online control relatively earlier in SB. Overall, the SB condition improved planning, execution, and accuracy of reaching movements for individuals with CP.
