Description
Technical field
The invention belongs to computer application and medical rehabilitation field, and in particular to a kind of multi-channel nerve function quantitative is evaluated
System.
Background technology
Human society has entered into aging society, and the chronic disease of harm elderly population turns into the important disease for threatening human health
Disease.Wherein, cerebrovascular disease, dementia, the Parkinson's of influence nervous function are in rising trend in the worldwide incidence of disease,
The characteristics of with high mortality, high disability rate, patient's life-span and quality of life are had a strong impact on, bring heavy negative to society and family
Load.
The diagnosis process of these diseases need to generally undergo clinical data collection, doctor and be judged according to knowledge and experience, finally
Form the process of diagnosis.Therefore, nervous function and structure volume data evaluation, collect be diagnosis of nervous system diseases and
The foundation stone of research.
Nervous system includes perception, cognitive and three partial functions of motion, due to the functional localization feature of nervous system, to upper
Stating the evaluation of three partial functions most can directly judge whether nervous system is undermined damaged part.For a long time, various bodies
Sense, motor function evaluation method and cognitive function assessment method are widely used in clinic, can itemize and evaluate vision, the sense of hearing, touch
The many nervous functions of feel, memory, notice, operation perform function, muscular strength, Muscle tensility, mutual aid, balance etc..
Neurosurgeon and the nervous system disease researcher carry out routine work using above-mentioned evaluation method.It is clear that
These evaluation methods place one's entire reliance upon the experience of estimator, qualitative subjective evaluation are carried out to nervous function, although part evaluation side
Method has hierarchical concept, but this classification is not undoubtedly the quantitative data of equivalent difference.Its deficiency mainly has the following aspects:①
Estimator's subjective judgement determines evaluation result;2. non-quantitation data;3. dependent on scene evaluation and test, information-based, digitized degree is low,
Whole data storage and recovering and analysis can not be carried out to detection key element.
Therefore, because the complexity of nervous system structures and function, it is existing volume data evaluate collection mode have according to
The characteristics of relying subjective experience to judge, can not quantify and lack globality, clinical diagnosis and clinical research to the nervous system disease
Bring great uncertainty.
