- Abstract:
- Motor dysfunction of cerebral palsy is usually characterized by abnormal crawling postures such as rabbit-hopping, ataxia and left-right swaying in the early crawling stage, but there is still a lack of objective and quantized measurement methods for clinical evaluation of these abnormal crawling postures in children with cerebral palsy. Based on acceleration sensors and inter-joint coordination analysis theory, a measurement and analysis system is designed for abnormal crawling postures in children with cerebral palsy. The system mainly includes the following functions: (1) acceleration data acquisition based on MPU9250 sensors (2) inter-joint coordination analysis based on acceleration signals and non-negative matrix decomposition algorithm. The design initially implements the acquisition and storage of acceleration data from the main joints of limbs during crawling, as well as realizes the feature analysis on inter-joint coordination.
