Technical field
The present invention relates to a kind of grading device, particularly relate to a kind of measuring device being exclusively used in Parkinsonian's lower limb flexibility ratio and judging, when further relating to experiment to parkinson patient carry out world unify the 26th project in parkinson disease rating scale Part III lower limb flexibility ratio is evaluated in needed for measuring device.
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 26th test item of Part III is lower limb flexibility ratio, the mainly motility of lower limb under knee sprung state, and mainly refer to that heel of repeatedly having stood on tiptoe fast makes lower limb lift, heel raises at least 6cm; Usually five kinds of state displays are had: (1) 0 represents normal condition; (2) 1 represent that action is slightly slowed down or amplitude slightly diminishes; (3) 2 represent moderate infringement; Cardinal symptom performance has senilism, can have interval, and namely amplitude reduces, and is easy to tired, has time-out once in a while in action; (4) 3 represent grievous injury, and comprise difficulty in starting, midway interval, hesitate when namely action starts, action has break-off phenomenon in carrying out; (5) 4 expressions almost can not complete test;
According to this table analysis, the condition of Measurement accuracy lower limb flexibility ratio comprises: 1, the standard operation of project testing is that quick heel of repeatedly having stood on tiptoe makes lower limb lift, and the too high at least 6cm of heel; 2, the not free restriction of test process; 3,5 ranks are divided into the evaluation of lower limb flexibility ratio: normal; Slight obstacle; Obvious obstacle; Serious hindrance; Almost can not complete; Parkinsonian judgement is carried out, mainly according to the situation of the evaluating basis observation test person of these 5 ranks according to this table; But, to the standard foundation that the observation of tester is often fixed, quantized; Therefore, for same patient, the test of different time sections does not have unified standard, the evaluation criterion that the evaluation for multiple even large quantities of patient is ununified yet, and different experiments, different test mans carries out the standard of this project testing standard ununified especially to patient; Even if in same test, tester is owing to having different states in different time, the standard under different conditions is very non-constant, and test result may be caused to produce severe deviations with the practical situation of patient in experiment; When comparing to different experiments, because standard is uncontrollable, this skew may be larger;
Because above conventional test methodologies exists many disadvantages, can not accurately and the degree that cannot decline to the lower limb flexibility ratio of patient or development process make and confirming accurately, slip up causing the test of the 26th project, and then cause the error of motor function so that the scoring of UPRDS Part III, then cause the error of follow-up correlation analysis;
