Neurological in origin, Motor Skills Disorder (MSD) is a developmental disorder that impairs motor coordination in daily activities. Many kids with High-Functioning Autism (HFA) and Asperger’s (AS) experience deficits in motor skills development, which often manifest as abnormal clumsiness (although it may not be major enough to be considered a disorder in and of itself).
MSD is a result of weak or disorganized connections in the brain, which then translates to trouble with motor coordination. Movements are performed because the brain sends messages to the area requiring action. MSD is a result of weak or poorly structured neural pathways to the moving parts of the body.
Clumsiness is a matter of poor balance and gross motor coordination. The origin of this deficit is the vestibular system of the inner ear. The vestibule is an organ responsible for maintaining balance and coordination and is located beside the cochlea, which acts as a sound receptor. Although they attend to different information, the proximity of the vestibule and cochlea allows them to work together. But, if one system is not functioning well, the other is concurrently affected.
