Objective of the study was to test and analyze benefits of a new motor-progress-facilitating socio-psychological adaption model for the musculoskeletal-disorders-diagnosed preschoolers and their families. Methods and structure of the study. We sampled for the motor-progress-facilitating socio-psychological adaption model testing experiment the musculoskeletal-disorders-diagnosed children and their family members (n=122+122). Progress of the sample was tested by seven survey methods, including two questionnaire surveys of our own design to rate the motor progress and self-serving skills. The experimental model was designed to advance the family socio-psychological adaption by three adaptive physical education courses for the children with the family counseling on every issue of the musculoskeletal-disorders-diagnosed child upbringing and training. Results and conclusion. The motor-progress-facilitating socio-psychological adaption model was tested to improve the family socio-psychological adaption resource, with the group motor skills tested to grow by 2.19 points and self-serving skills to 9.65 points on average. The model with the test data and analyses is recommended for application by the adaptive physical education specialist community in the preschool education, rehabilitation and other relevant establishments.
