Multi-finger grip function test analyzer and method based on multi-directional stable deflection moment

Abstract

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.

Description

technical field [0001] The present disclosure relates to the field of finger grip function testing, in particular to a multi-finger grip function test analyzer and method based on multi-directional stable deflection moments. Background technique [0002] The hand is one of the most precise and distinctive organs on the human body, and it is also one of the three important organs that make people highly intelligent. The main function of the hand is to grasp and manipulate objects. [0003] Accurate testing of hand grasping function is an important technical requirement in the fields of neurophysiology research, clinical pathology testing, health screening and disease prevention. [0004] The generalized hand grip function mainly includes two aspects: "hand grip strength" and "hand grip motor control". evaluate. During the research and development process, the inventor found that the existing form of evaluation of fine motor control of fingers is mainly a doctor's subjectiv...

Problems solved by technology

During the research and development process, the inventor found that the existing form of evaluation of fine motor control of fingers is mainly a doctor's subjective diagnosis and analysis, so that the tester completes the specified task and fills in the scale to draw a conclusion. For example, the Wolf Motor Function Evaluation Scale is mainly used to To evaluate the rehabilitation status of hemiplegic upper limb motor function, however, the scope of this method is narrow and limited to mild to moderate stroke patients; at the same time, the scale has too many items and the evaluation time is long, so it is deleted Whether certain items can maintain high reliability and validity needs to be further studied, and the method of scoring functional ability by observing the completion of the tester has certain subjectivity. Different doctors may get different results. Quantitative and accurate assessment
