摘要
The present disclosure discloses a multi-finger grasping function test analyzer and method based on multi-directional stable deflection torques, which can accurately detect and quantitatively assess the grasping function of all five fingers participating simultaneously. The test analyzer comprises a test device and a processor; the test device is configured to measure multi-directional three-dimensional forces and three-dimensional torques during the grasping process of subject's fingers; and the processor is configured to acquire the multi-directional three-dimensional force and three-dimensional torque data of the fingers measured by the test device to form multiple three-dimensional force and three-dimensional torque vector time series, perform multi-scale sample entropy analysis on the multiple three-dimensional force and three-dimensional torque vector time series to obtain dynamic coupling complexity values of multi-time scales, and calculate an indicator of dynamic coordination between the fingers.
