With the renewal of medical philosophy, the concern for children with congenital heart disease is no longer limited to the structural problems of the heart, but the overall growth and developmental status and quality of life of children with congenital heart disease are getting more and more attention. Many medical reports show that children with congenital heart disease have significantly lower motor development than normal children, 60% of children with congenital heart disease have moderate or severe motor impairment, and children with congenital heart disease with mild uncorrected lesions and no residual lesions after surgery also have reduced motor development, and many of the reasons for the reduction are due to overprotection by parents, health care providers, educators, or other health professions, and most children with congenital heart disease Children’s physical activity does not meet healthy physical activity guidelines, and children with predilection are at greater risk for developmental delays, cognitive behavioral abnormalities, and speech impairment. Growth and development assessment, rehabilitation management, continuous monitoring and regular follow-up during the treatment process are very important and indispensable, and need the high attention of medical staff and parents. The Peabody Developmental Motor Scale (PDMS) is a comprehensive motor function assessment scale that is widely used in China and abroad to assess the motor development of all children from 0 to 72 months of age. The PDMS has both quantitative and qualitative functions and consists of two separate components, the Gross Motor Assessment Scale (GMS) and the Fine Motor Assessment Scale (FMS), which can assess the gross motor and fine motor development of children respectively. The Gross Motor Assessment Scale consists of 151 items that test the abilities of five skill areas, including reflexes, balance, acquisition and release, fixation, and movement; the Fine Motor Assessment Scale consists of 98 test items that test the abilities of four motor skill areas, including grasping, hand use, hand-eye coordination, and manipulative dexterity. At the end of the test, the PDMS scale can give five kinds of scores: raw score, equivalent age, percentage, standard score for each subtest, and the combined developmental quotient, all of which have different meanings and uses. The raw score is the sum of all the scores of each test; the equivalent age is calculated from the raw score of each subtest and represents the age at which the test taker is able to move in the energy area measured by the subtest, which can be used to understand the actual age of the baby; the percentage allows parents to see clearly where the child’s ability is in the overall peer group; the standard score can most clearly The standard score is the most reliable score that the PDMS can give, by adding up the standard scores of different subtests and converting them to obtain the gross motor development quotient, the fine motor development quotient, and the overall motor development quotient, respectively. and overall motor development quotient. Gross motor is the movement that involves large muscles and most of the body, and is the overall movement of the trunk and limbs, including lifting, rolling over, sitting, climbing, standing, walking, running, jumping, etc. Gross motor developmental quotient is derived from a combined analysis of scores from several subtests that test the applied function of the large muscle system and reflects the ability to apply the large muscle system to respond to environmental changes, maintain posture when movement is not required, move from one location to another, and grasp, throw, and kick a ball. The fine-motor development quotient is the child’s ability to grasp objects, build blocks, draw pictures, and control objects using the fingers, hands, and part of the arms. The fine-motor development quotient is the result of a combined analysis of two tests of the small muscle system applied functional subtests, which test the child’s level of fine-motor development. The overall motor development quotient is derived from the combined analysis of all gross motor subtests and fine motor subtests. Therefore, these developmental quotients can be compared between different populations and can be a good indicator of the overall level of functioning of the tested person, and the overall motor development quotient is the best indicator to assess the overall motor development level. Currently, the PDMS has been very widely used internationally, and in general the PDMS has some uses: the results of the PDMS can be used to evaluate a child’s motor skill level relative to children of the same age; the gross motor development quotient and the fine motor development quotient of the PDMS can be compared with each other to determine whether there is a difference in a child’s gross motor and fine motor development levels; the application of the The PDMS can be used to analyze both quantitatively and qualitatively the motor skills of each individual, and the motor skill deficits of the test subjects can be identified and translated into individual training goals; the PDMS can be used to evaluate the motor skill progress of a child. In summary, the PDMS is a comprehensive motor function assessment scale that is useful in determining a child’s motor function level, developing treatment plans, and identifying intervention programs and evaluating treatment outcomes. the PDMS test takes approximately 45-60 minutes. Children with congenital heart disease need regular motor development assessment to form a continuous monitoring process, which is recommended every 6 months. Only in this way can motor, speech and behavioral disorders that occur in children with congenital heart disease be detected early, so that appropriate rehabilitation and health guidance programs can be developed early.
