Table 1_Motion matters: visual perception and motor functioning in children and youths with spastic cerebral palsy.docx

In individuals with cerebral palsy (CP), a condition characterized by disorders of movement and posture attributed to disturbances of the developing brain, Cerebral Visual Impairments (CVI) are common. CVI involves difficulties with organizing and interpreting visual information.

Gait alterations and activity limitations in children with CP such as reduced; walking speed, step length, and motor skill performance, may be over-attributed to the motor and musculoskeletal disorders. Knowledge of how visual perception influence motor functioning in individuals with CP is sparse. The aim of this study was to investigate global motion perception, the ability to interpret the coherent direction of visual motion, and reported features of CVI in children and youths (C&Y) with spastic CP at different levels of motor functioning.</p>Methods<p>C&Y aged 8–20 (mean age 14:4) years, CP; 37 (gross motor functioning classification system, GMFCS, I; 28, II-III; 9) and typically developing (TD); 36, performed a computer-based Visual Motion Coherence Test (VMCT) evaluating global motion perception at three velocities (score: 0.0–1.0, low scores indicate difficulties).
