Abnormal spinal morphology has become one of the physical and mental health hazards of children and adolescents.To meet the needs of universal spine health screening,this study designs an intelligent handheld device for spinal morphology screening.Based on the inertial sensor and rolling operation mode,the device implements the dynamic collection of multi-parameter spinal shape,the construction of virtual simulation model,the measuring of Cobb Angle,the determination of spinal morphology type,etc.,and is matched with interactive software on intelligent mobile terminal.The comparative experimental results show the test results of this device have high correlation with the manual measure-ment results of professional physicians,with the advantages of shorter detection time,more convenient operation,and intelligent display and so on.
