This study investigates the potential advantages of employing a multisensory integration approach in motor learning and performance. By repeatedly stimulating various sensory systems, such as combining visual and auditory cues, the brain may effectively process and learn from relevant sensory stimuli. The research focuses on examining the control and coordination of reaching and grasping a tennis ball in six children with cerebral palsy (CP) under two conditions: a non-sound ball (NS) condition and a pure tone sound (PTS) ball condition, from their seated positions. Quantitative data on upper limb movement were collected using a 3D Qualisys motion capture system. Preliminary findings suggest that the audio-visual condition (pure tone sound ball) demonstrated a more synchronized movement pattern compared to the visual condition (non-sound ball). This suggests that the addition of sound cues to the ball may have facilitated the integration of multiple sensory inputs. Consequently, children were able to simultaneously utilize visual and auditory information to guide their hand movements. This integration of sensory cues likely promoted increased attention to relevant sensory inputs, ultimately resulting in improved motor performance.
