Problems solved by technology

However, this evaluation method is usually affected by the operating experience of the scoring physician and the state and emotion of the person being tested during the evaluation, so the evaluation results are still not objective and accurate enough.

Embodiment Construction

[0047] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0048] The "pointing" and "fist" gestures are two commonly used international standard indicators for assessing the hand motor ability of Parkinson's patients. In the following, the two specified actions will be taken as examples to describe how to evaluate the hand motor ability of Parkinson's patients in combination with specific embodiments. However, it should be understood that the embodiments of the present invention are not limited to specific sports actions, and the principles of the present invention may also be applied to other actions or the assessment of the athletic ability...

Abstract

The invention provides a method and system for quantitative evaluation on the hand motion ability of patients with Parkinson's diseases. Hand surface electromyographic signals of an examinee during the specific action execution are captured by a wearable electromyogrphic transducer; and the hand motion capability of the examinee is subjected to quantitative evaluation on the basis of a trained motion capability classifier corresponding to the specific action by extracting time domain features and frequency domain features from the surface electromyographic signals and the features relevant to the completion conditions of the specific action. By using the method and the system, the hand motion capability of the patients with Parkinson's diseases can be objectively and accurately subjected to grade evaluation.

Description

technical field [0001] The invention relates to the quantitative evaluation of motor ability, in particular to a quantitative evaluation method and system for Parkinson's patient's hand motor ability. Background technique [0002] The motor symptoms of patients with Parkinson's Disease (PD) mainly include slowness of movement, resting tremor, and muscle stiffness. At present, the detection and evaluation of the motor ability of PD patients mainly relies on the PD Rating Scale (Unified Parkinson's Disease Rating Scale, UPDRS) provided by the International Sports Association for grade evaluation. For example, the hand motor ability of Parkinson patients is usually divided into It is graded from 0 to 4. Grade 0 is equivalent to the hand motor ability of normal people. The higher the grade, the worse the hand motor ability. However, this evaluation method is usually affected by the scoring physician's operating experience and the state and emotion of the person being tested dur...
