I. Neural mechanism
1. Genetically determined neural network instruction system
Fetal and neonatal movements: feeding, breathing, foraging, sucking, blinking, coughing and gargling, etc. Infant walking, whole body movement, etc.
This is the instinct for survival of life.
2. Acquired motor experience
Movement is present in every moment of life, whether it is touching, running, talking, or blinking. All movement depends on muscle activity.
Second, the conditions required for the development of normal motor function
1.Normal brain function
Motor center – brain, cerebellum, subcortical thalamus and basal ganglia normal spinal cord and peripheral nerves bones, muscles, tendons complete and sound sensory system.
2.Motor disorders
(1) neurological abnormalities caused by.
(2) Biomechanical abnormalities: that is, mechanical abnormalities cause abnormal movements.
3.Common problems and diseases of motor development
Delayed motor development.
(1) Just gross motor development is backward, i.e., individual differences.
(2) Backward, may suffer from neuromuscular diseases, mild hemiplegia, mild ataxia, mild cerebral palsy.
Overall developmental backwardness: i.e., overall backwardness in mental retardation, motor, language, social, and adaptive
Cerebral palsy.
Motor developmental backwardness and abnormalities
Neurological abnormalities
May or may not be accompanied by language, intellectual or social impairment
Neuromuscular disorders.
Abnormalities at birth, or sometime after birth, varying from disease to disease, mostly manifested by hypotonia, i.e. floppy children
Skeletal and joint problems.
For example: congenital hip dislocation, injury to bone and joint, inflammation, etc.
About nutritional problems
Severe malnutrition: medical history with recurrent diarrhea, pneumonia, etc.
Rickets (calcium deficiency): Severe rickets can cause delayed motor development.
