ObjectiveTo develop a rehabilitation program of nature posture treatment (NPT) suspension therapy based on the International Classification of Functioning, Disability and Health-Children and Youth version (ICF-CY) framework, and apply it to neurodevelopmental disorders. MethodsThe ICF-CY theoretical group (group A) and NPT suspension therapy group (group B) were established. Group A searched literature from common databases, to extract high-frequency words related to suspension therapy and match with categories of ICF-CY, to develop ICF-CY theoretical framework of the NPT suspension therapy. Group B developed specific rehabilitation procedures and training items based on the framework to compose the training pool. A total of 110 children aged less than six years with neurodevelopmental disorders and associated motor impairments were selected from outpatient or inpatient of the First Affiliated Hospital of Xinxiang Medical University, between October, 2019 and October, 2022. They were randomly divided into control group (n = 55) and clinical group (n = 55), who received routine neurodevelopmental therapy and NPT suspension therapy program based on ICF-CY, respectively, for a week. The incidence of satisfaction, acceptance and adverse events were observed. ResultsTwo cases in the control group and four cases in the clinical group dropped down. For the clinical group, the incidence of satisfaction was 98% (50/51), with acceptance of 96% (49/51), and one adverse event occurred. For the control group, the incidence of both the satisfaction and acceptance was 100%, and no adverse event occurred. There was no significant difference in the incidence of satisfaction, acceptance and the adverse event (P > 0.05). ConclusionThe NPT suspension therapy program based on the ICF-CY framework is safe and acceptable for children with neurodevelopmental disorders.
