Description

A kind of measuring device and method pointing kneading ability for Parkinsonian

Technical field

The present invention relates to a kind of grading device, particularly relate to the grading device that a kind of Parkinsonian of being exclusively used in points the judgement of kneading ability.

Background technology

Parkinson disease are a kind of person in middle and old age's neurodegenerative diseases, its Clinical symptoms is usually expressed as static tremor, bradykinesia, hypermyotonia and postural balance obstacle, and its pathological characteristic mainly contains 3 points: (1) selectivity substantia nigra of midbrain dopaminergic neuron is lost; (2) Striatal Dopamine Content significantly reduces; (3) there is Lewy body in black substance and locus coeruleus;

At present, for Parkinsonian diagnosis, Parkinsonian international clinical criteria is normally adopted to diagnose: concrete criterion is as follows: (1) static tremor, bradykinesia, gear sample myotonia and Postural reflecting barrier, the feature that Parkinsonian one of at least to need to have in static tremor, bradykinesia two; (2) Parkinsonian symptoms of patient and sign are not due to cerebral trauma, cerebrovascular disease, the cerebral tumor, viral infection or other known nervous system disease, and caused by known medicine and chemical toxicant; (3) patient must possess following sign: significantly property apparent motion obstacle, cerebellum disease, nuclearity dysphonia, postural hypotension (change is more than more than 30mmHg), cone infringement and amyotrophy altogether on core; (4) Dopar test effectively; The patient simultaneously meeting above-mentioned four standards can clinical diagnosis be parkinson disease; But the concordance being through parkinson patient that this clinical criteria diagnoses out and pathological diagnosis only has 70%-75%, and its specificity is not high; In clinical research and epidemiological study, for ensureing the accuracy of diagnosis as far as possible, except requiring that patient meets except above-mentioned four standards, also whether the symptom of demand fulfillment patient and sign have asymmetric must performance when onset or in the course of disease, if patient occurs asymmetricly showing that Parkinsonian specificity will improve significantly to about 90%;

But above-mentioned Parkinsonian clinical symptoms is mainly based on motor symptoms, but still there is non-motor symptoms, mental symptom that non-motor symptoms mainly comprises (1), is embodied in attention deficit; Personality, disturbance in cognition; Vision (visual space disturbance of perception, color discrimination capability deteriorates), disturbance of consciousness; Depressed; Indifferent; Lack pleasant sensation; Intense; Manic; Anxiety; Visual hallucination; Computing power, memory, orientation force, judgment are lost; (physiology) illusion; Dull-witted; Cognitive impairment (intellectual function, psychomotor control, the exception of high-level cognitive function and cognitive Plasticity); Lively dreamland; (2) autonomic nerve symptom, is mainly manifested in constipation, postural hypotension, perspiration, sexual dysfunction, dysuria, sialorrhea; (3) sensory disturbance, is mainly manifested in numbness, pain, spasm, ekbom syndrome (RLS), anosmia; (4) sleep disorder, is in particular in insomnia, uneasy lower limb syndrome (RLS), periodic limb movement (PLM), rapid eye movement (REM) sleep, nonrapid eye movements,sleep, behavior disorder, the daytime is drowsiness;

Therefore, should Comprehensive Treatment be taked for the motor symptoms of PD and non-motor symptoms, comprise Drug therapy, operative treatment, rehabilitation, psychotherapy and nursing etc.; Drug therapy, as first-selection, is the essential therapeutic arsenals in whole therapeutic process, and operative treatment is then the effective means of supplementing out economy of one of Drug therapy; No matter the treatment means of current application is medicine or operation, all can only improve symptom and can not stop the development of the state of an illness, more cannot cure; To the treatment of parkinson patient, effectively improve symptom to reach, improve the quality of living as target, adhere to " dose titration ", " reaching promising result with minimum dose "; Treatment should be different according to individuation feature difference; Therefore, to the determination of PD symptom, the state of an illness can be specified and improve or worsen further, and with the selection of therapeutic scheme with define great and close relationship;

To the judgement in stage residing for parkinson patient, unified parkinson disease rating scale (Unified Parkinson ' s Disease Rating Scal, UPDRS) are generally adopted to assess in the world; Score value is higher, and PD symptom is more serious; UPDRS is used to summarize the unified scale measuring parkinson patient various aspects ability, is divided into three parts: Part I: spirit, behavior and emotion (comprising test event 1-4); Part II: daily routines (comprise test event 5-17, filled in by patient); Part III: motor function (comprise test event 18-31, doctor checks); Part IV: the complication (comprise test event 32-42, refer to last week) for the treatment of; But, use in UPDRS in reality, be but faced with numerous difficulties, mainly the defining standard disunity of some projects, cause its accurate evaluation to cause great difficulty; In these four parts, first and second, the test of the most projects of four parts has fixed quantisation standard, be easier to measure, and the testing standard of some projects of Part III is fuzzyyer, and maintain fixing more difficult when some standards quantized are measured in repeatedly different occasion by examiner; Wherein, the 23rd test item of Part III is mediated for finger, and mainly the kneading of thumb and forefinger amplitude peak, the fastest frequency, specifically comprises following content: (1) normal (>15 time/5 seconds); (2) comparatively slow, the amplitude less (11-14 time/5 seconds) of frequency; (3) obvious obstacle: senilism, interval (7-10 time/5 seconds) can be had; (4) serious hindrance: comprise difficulty in starting, midway interval (3-6 time/5 seconds); (5) tensible forefinger (0-2 time/5 seconds) hardly; Known according to this standard, the condition of Measurement accuracy finger kneading ability is: the standard operation that (1), finger are mediated is the kneading of thumb and forefinger amplitude peak, the fastest frequency; (2), time restriction is within 5 seconds.(3), to the evaluation of finger pinch function be divided into 5 ranks, be respectively: 1. normal; 2. frequency is comparatively slow, amplitude is less; 3. obvious obstacle; 4. serious hindrance; 5. tensible forefinger hardly; The evaluating basis of these 5 ranks is the kneading number of times in 5 seconds, specific as follows: if it is for 15 times normal that kneading number of times is greater than; Be greater than and be less than 14 times for 11 times for frequency is comparatively slow, amplitude is less; Be greater than 7 and be less than 10 times for obvious obstacle; Be greater than 3 and be less than 6 times for serious hindrance; Be less than 2 times for tensible forefinger hardly; To above-mentioned standard according to carrying out refinement magnitude again, it can thus be appreciated that, 15 and 14,11 and 10,7 and 6, be only all because a difference of taking second place can cause different gradings between 3 and 2;

And in practical operation, in order to control group difference, also in order to save manpower, often need an operator to evaluate these projects; For an operator, before this project of mensuration, patient association be taught and carry out thumb and forefinger with the kneading of amplitude peak, the fastest frequency; In order to avoid patient forgets, within short 5s, operator should parameters, observe stopwatch change, also want the number of times of number of observation and counting, also to reject and mediate standard compliant kneading in the middle part of number of times, record effectively mediates number of times, and these job contents, for an operator, are unaffordable work load and pressure at short notice; Look back the standard of Measurement accuracy, if 1 counting be in 15 and 14 by mistake, 11 and 10,7 and 6, between 3 and 2, the larger error of measuring and grading will be caused; Especially between 15 and 14 times of rapid movement, will cause the qualitative error of grading, because it is for 15 times normal for being greater than, and be for 14 times abnormal, namely frequency is comparatively slow, amplitude is less;

Defect above on all traditional operations, not accurately and the degree that cannot decline to the finger of patient ability of mediating or development process make the problems such as confirmation exactly, slip up causing the test of the 23rd project, and then cause the error of motor function so that the scoring of UPRDS Part III, then cause the larger problems such as the error of follow-up correlation analysis;

In order to meet to the precise requirements measured in height-precision experiment, the present invention designs a kind of letter pointed kneading ability and judge; Particularly, when a series of research carrying out parkinson patient, by finger pinch function grading device, this device is the high accuracy appreciable levels and follow-up study analysis foundation accurately that accurate parkinson disease finger can be provided to mediate ability, parkinson patient is provided information in finger pinch function accurately, the finger motion function of parkinson patient can be learnt simultaneously, learn PD, prevent accident and carry out treating the finger pinch function grading device detected.
