The following phenomena must be taken seriously by parents to consider sensorimotor disorders and seek professional participation in sensorimotor training: First, visual abnormalities: children have difficulty with eye movements, poor hand-eye coordination, and often misread words, numbers, and radicals. Second, vestibular function and movement abnormalities: children do not spin in circles or are afraid to rotate their bodies, have poor body balance, fall easily, do not walk in a straight line, move awkwardly, and have difficulty jumping rope and riding bicycles. Third, abnormalities in skin sensation such as touch: children are too sensitive or too dull to tolerate exogenous contact with body skin such as shampooing, bathing, and changing clothes. There may also be abnormalities in the senses of smell, location or pain. Fourth, timidity and fear: hate shaking, afraid to climb high, unable to go down stairs smoothly, slow to adapt to unfamiliar environment. Fifth, abnormalities in other mental activities: such as poor concentration, persistence and distribution of attention, and inefficiency in doing things. The causes of individual sensory integration disorder are multifaceted and can be broadly divided into three aspects: genetic factors, environmental factors and genetic and environmental interaction factors. Individuals with sensory integration disorders are mostly the result of the interaction between genetic and environmental factors, and there are large individual differences.
