background

Most of the movements in daily life need to be accomplished through hand functions, such as arm lifting, bending, grasping, pinching, rotating and the like. Persons with a decline or loss of upper limb motor function due to certain factors need to be comprehensively evaluated in order to develop a proper rehabilitation plan and evaluate the progress of the patient's rehabilitation.

the assessment of upper limb function typically includes static assessment and dynamic assessment. Static evaluation is simply a visual inspection of the patient's hand and a measurement of dimensions, such as degree of trauma, degree of deformation, physiological dimensions, etc. Dynamic assessment refers to the assessment of the patient's hand (including arm) motor abilities, including range of motion, strength, speed, etc. The evaluation means comprises the steps of doing some specified actions under the guidance of a doctor, such as arm stretching, grasping a prop with a specific shape and the like, and finally making evaluation by the doctor according to the performance of the patient.

In the existing upper limb function evaluation system, static evaluation is the basis of all evaluation and diagnosis, which can not only carry out accurate diagnosis measurement by means of professional examination equipment, but also carry out measurement and evaluation by doctors through visual examination or experience, but the result of the static evaluation cannot well guide the rehabilitation treatment process or evaluate the rehabilitation progress. The hand motion function of the patient can be accurately evaluated by means of dynamic evaluation guided by the doctor, but the evaluation result can be greatly influenced by the doctor because the process requires deep participation of the doctor, for example, the professional level and the working habit of different doctors can influence the evaluation result, and in addition, the evaluation method is difficult to be carried out in real time in the rehabilitation training process of the patient, so that the patient and a rehabilitation therapist cannot know the rehabilitation progress of the patient in real time.

Therefore, it is urgently needed to provide a new upper limb function evaluation method for solving the problems that dynamic evaluation cannot be performed simultaneously with rehabilitation training in the prior art and the like.
