The Peabody Motor Development Scale is an excellent scale for assessing motor development in infants and toddlers written by experts in motor development assessment and intervention therapy in the United States. The scale consists of six subtests, including posture, reflexes, movement, physical manipulation, grasping and visual-motor integration, with results expressed as gross motor, fine motor and total motor development quotients. Gross motor assesses the child’s ability to respond to environmental changes, maintain postural balance, move and catch, throw and kick a ball. Fine motor assesses the child’s ability to use fingers, hands and upper arms to grasp, draw and manipulate objects. The total motor quotient consists of two components: gross motor quotient and fine motor quotient. The scale is not only applicable to children aged 0-5 years with motor developmental delays and the evaluation of motor rehabilitation, to understand the percentile and developmental equivalent age of the child’s various skills among children of the same age, but also the accompanying motor training program, which can be targeted and effective for rehabilitation.
