Description

本発明は、被験者の異常眼球運動(眼振)を記録する眼振記録装置に係り、特に、基礎医学や臨床医学において適用可能なめまい患者の診断に際して有効な眼振記録装置及びこれを用いた眼振検査システムに関する。   The present invention relates to an nystagmus recording device that records abnormal eye movements (nystagmus) of a subject, and in particular, an nystagmus recording device that is effective in diagnosing dizziness patients applicable in basic medicine and clinical medicine, and the same. The present invention relates to an nystagmus inspection system.

従来、基礎医学や臨床医学においては、めまい検査の一手法として眼振検査が既に知られている。
この種の眼振検査は、一般的に、病院の検査室にて電気眼振検査計(ENG:Electro Nystagmo Graphの略)を利用して行われる(例えば特許文献1,2参照)。
特許文献1には、ENGを用いた検査方法として、被験者に検査目的に応じた刺激を与え、それから得られる眼振図によって診断が行われていたことが開示されている。ここで、前記刺激の与え方としては、耳の近くに電気刺激を与えたり、耳内に一定の冷水又は温水等を注入したり、空気を出し入れし、加圧、減圧したり、スクリーン上に描かれた像を目で追わせたり、被験者を回転椅子に乗せて回転する方法などがある。
特許文献2には、被験者に提示する映像によって被験者の眼球を左右に往復運動させ、眼球の動きを眼球計測手段により計測し、この計測データに基づいてリズムゆらぎ解析を行う技術が開示されている。
Conventionally, in basic medicine and clinical medicine, nystagmus examination is already known as a technique for vertigo examination.
This type of nystagmus test is generally performed using an electrical nystagmus tester (ENG: Electro Nystagmo Graph) in a hospital laboratory (see, for example, Patent Documents 1 and 2).
Patent Document 1 discloses that, as an inspection method using ENG, a stimulus is given to a subject according to the inspection purpose, and diagnosis is performed based on an nystagmus obtained therefrom. Here, as a method of giving the stimulus, an electrical stimulus is given near the ear, a certain amount of cold water or warm water is injected into the ear, air is taken in and out, pressure is increased or reduced, or the screen is placed on the screen. There are methods to follow the drawn image with the eyes and to rotate the subject on a swivel chair.
Patent Document 2 discloses a technique in which a subject's eyeball is reciprocated left and right by an image presented to the subject, the movement of the eyeball is measured by eyeball measurement means, and rhythm fluctuation analysis is performed based on this measurement data. .

また、夜間睡眠中においても眼振記録を行う要請があり、例えば睡眠時無呼吸症候群の診断に利用されている(例えば特許文献3参照)。
この種の検査としては、病院の検査室にて睡眠ポリグラフ(PSG:Polysomnographyの略)と呼ばれる装置を用い、脳波、筋電、眼電、心電などの様々な生理データを計測し、睡眠深度、レム睡眠/ノンレム睡眠の状態を把握する手法が一般的であるが、被験者の額部に装着し眼球運動を計測する手段と、外乱の状況を計測する手段とを一体化し、外乱の大きさが予め設定した閾値を超えたときに外乱を受けていると判断し、眼球運動の情報から外乱の影響を修正する簡易型の睡眠状態検出装置も既に提供されている。
In addition, there is a request to record nystagmus during sleep at night, which is used for diagnosis of sleep apnea syndrome (see, for example, Patent Document 3).
This type of examination uses a device called a polysomnography (PSG) in hospital laboratories to measure various physiological data such as electroencephalogram, electromyography, electrooculogram, and electrocardiogram, and the depth of sleep. The method of grasping the state of REM sleep / non-REM sleep is common, but the size of the disturbance is integrated with the means for measuring eye movements and the means for measuring eye movements worn on the subject's forehead. There is already provided a simple sleep state detection device that determines that a disturbance is received when the threshold value exceeds a preset threshold and corrects the influence of the disturbance from the information of eye movements.

更に、睡眠中の眼振については、非特許文献1,2には、内耳性めまい患者の病的眼振がレム睡眠時には抑制されると報告されており、また、非特許文献3,4には、中枢性疾患においてレム睡眠下眼振が正常者と比べ異常に出ると報告されており、睡眠中の眼振を検査することは、内耳性疾患や中枢性疾患に対して診断的意義が高いものと言える。   Furthermore, regarding nystagmus during sleep, Non-Patent Documents 1 and 2 report that morbid nystagmus in patients with inner ear vertigo is suppressed during REM sleep, and Non-Patent Documents 3 and 4 Has been reported to cause abnormal REM sleep nystagmus in central diseases compared to normal subjects, and examining nystagmus during sleep has diagnostic significance for inner ear diseases and central diseases. It can be said that it is expensive.

しかしながら、特許文献1,2に示すように、従来における眼振検査としてENGを用いた手法は、検査装置の大きさのために耳鼻咽喉科外来において検査室にて行われることから、被験者の生活環境の中でのめまい発作を捉えることは難しかった。また、仮にめまい発作期であっても、必ずしも検査時間中に特徴的な発作が生じるとは限らず、めまい発作を正確に記録することは適わなかった。
更に、PSGを用いた睡眠状態検査では、PSGが病院の検査室設置型の大型機器であることから、被験者の生活環境の中での睡眠状態を正確に捉えることは難しい上、睡眠下での眼振を解析するものとは言えない。
更にまた、特許文献3に示す簡易型の睡眠状態検出装置では、被験者の生活環境の中での睡眠状態を正確に捉えることは可能かも知れないが、睡眠下での眼振を解析するものとは言えない。
However, as shown in Patent Documents 1 and 2, the conventional method using ENG as an nystagmus test is performed in an otolaryngology outpatient laboratory because of the size of the inspection apparatus, and thus the life of the subject It was difficult to capture dizzy seizures in the environment. Moreover, even if it is a vertigo seizure period, the characteristic seizure does not necessarily arise during an examination time, and it was not suitable to record a dizzy seizure correctly.
Furthermore, in the sleep state test using PSG, it is difficult to accurately capture the sleep state in the living environment of the subject because the PSG is a large device installed in the laboratory of the hospital. It cannot be said that the nystagmus is analyzed.
Furthermore, in the simple sleep state detection device shown in Patent Document 3, it may be possible to accurately capture the sleep state in the living environment of the subject, but the nystagmus under sleep is analyzed. I can't say that.

本発明は、以上の観点に立ってなされたものであって、被験者の生活環境に対応して被験者の異常眼球運動(眼振)を長時間に亘って記録可能とする眼振記録装置及びこれを用いた眼振検査システムを提供するものである。   The present invention has been made from the above viewpoint, and an nystagmus recording apparatus capable of recording a subject's abnormal eye movement (nystagmus) over a long period of time in accordance with the living environment of the subject. there is provided a nystagmus inspection system using.

−眼振解析−
本実施の形態において、眼振解析装置50は、頭位センサ21及び眼振センサ22からの計測情報を取り込んだ後、デジタルデータとして保存する。そして、保存されたデジタルデータについては必要な時間領域だけ区域設定した後に、眼振解析を開始する。

ここで、本実施の形態で用いられる眼振解析のアルゴリズムの一例について図5に基づいて説明する。
今、被験者に眼振が生じ、例えば眼球の左右方向運動を示すデジタルデータが図5に示すようなノコギリ刃状になっているものと仮定すると、デジタルデータのうち緩やかな坂はゆっくりと眼球が左右のいずれかの方向に移動していることを示し、急さな坂はその逆の方向へ急速に移動していることを示す。
このように、眼振とは、弓を引いて離すときのような緩除運動と急速運動とが交互に起こる状態である。
図中のデジタルデータのうち、1回のノコギリ刃部分が1回の眼振を意味し、これが1秒間に何回起こるかが(1)眼振の頻度(Hz)として算定されるものである。一方、(2)眼振数はめまい発作全体で何回眼振が起こったかとして算定される。
また、デジタルデータを微分変換すると、急速運動時(急速相)の微分波形は上下どちらかに棘状に突出した波形になり、予め閾値レベルを選定し、もとのデジタルデータ波形上で前記閾値レベルに対応するピーク閾値を決め、このピーク閾値の前後で変曲点1,2を割り出し、割り出した変曲点2から次の眼振の変曲点1に至るまでの変化(緩除相)から緩除相速度を算定するようにしたものである。そして、(3)最大緩除相速度は予め設定された区域内で算出した緩除相速度の最大値として算定される。
-Nystagmus analysis-
In the present embodiment, the nystagmus analysis device 50 captures measurement information from the head position sensor 21 and the nystagmus sensor 22 and then saves it as digital data. For the stored digital data, the nystagmus analysis is started after setting the necessary time region.
In the present embodiment, nystagmus analysis is performed on, for example, (1) nystagmus frequency, (2) nystagmus frequency, and (3) maximum gradual phase-out speed.
Here, an example of an nystagmus analysis algorithm used in this embodiment will be described with reference to FIG.
Now, assuming that the subject has nystagmus, for example, the digital data indicating the left-right movement of the eyeball has a saw-tooth shape as shown in FIG. It indicates that the vehicle is moving in either the left or right direction, and a steep slope indicates that it is moving rapidly in the opposite direction.
Thus, nystagmus is a state in which slow movement and rapid movement occur alternately when pulling and releasing a bow.
Of the digital data in the figure, one saw blade means one nystagmus, and how many times this occurs per second is calculated as (1) frequency of nystagmus (Hz). . On the other hand, (2) nystagmus frequency is calculated as how many times nystagmus occurred in the whole dizziness attack.
In addition, when differential transformation is performed on digital data, the differential waveform during rapid movement (rapid phase) becomes a waveform that protrudes in a spine shape in either the upper or lower direction, a threshold level is selected in advance, and the threshold value is selected on the original digital data waveform. The peak threshold corresponding to the level is determined, the inflection points 1 and 2 are determined before and after the peak threshold, and the change from the calculated inflection point 2 to the inflection point 1 of the next nystagmus (relaxation phase) The rate of gradual removal phase is calculated from (3) The maximum gradual phase removal speed is calculated as the maximum value of the gradual phase removal speed calculated within a preset area.

次に、本実施の形態に係る眼振検査システムの眼振解析例について説明する。
(1)めまい発作の発生時
今、図6に示すように、被験者Mに各センサ21,22(センサ23,24は省略)を装着し、眼振記録を行っていると仮定する。
今、めまい発作が発生する前では、被験者Mの頭位センサ21からの頭位データはあまり動いておらず、眼振センサ22からの眼振データも正常範囲になっている。
ところが、被験者Mにめまい発作が発生すると、被験者Mの頭位がめまい発作前に比べて大きく変化するため、頭位センサ21からの頭位データが激しく変化する。
更に、めまい発作に伴って被験者Mの眼振が異常になるため、眼振センサ22からの眼振データが正常範囲を外れて異常に変化する。
このように、被験者Mにめまい発作が起こると、頭位センサ21及び眼振センサ22からの計測データが大きく変化し、眼振検査においてめまい発作の発生が正確に把握される。
Next, an example of nystagmus analysis of the nystagmus examination system according to the present embodiment will be described.
(1) At the time of occurrence of dizziness attack As shown in FIG. 6, it is assumed that each of the sensors 21 and 22 (sensors 23 and 24 are omitted) is attached to the subject M and nystagmus is recorded.
Now, before the dizziness attack occurs, the head position data from the head position sensor 21 of the subject M does not move so much, and the nystagmus data from the nystagmus sensor 22 is in the normal range.
However, when a vertigo seizure occurs in the subject M, the head position of the subject M changes significantly compared to before the vertigo seizure, and thus the head position data from the head position sensor 21 changes drastically.
Furthermore, since the nystagmus of the subject M becomes abnormal with the dizziness attack, the nystagmus data from the nystagmus sensor 22 deviates from the normal range and changes abnormally.
Thus, when a vertigo seizure occurs in the subject M, the measurement data from the head position sensor 21 and the nystagmus sensor 22 change greatly, and the occurrence of the vertigo seizure can be accurately grasped in the nystagmus examination.

(2)REM睡眠時の眼振解析
図4及び図7(a)に示すように、睡眠解析の一つであるREM睡眠解析によりREM睡眠領域が算定されるため、REM睡眠領域にて眼振解析を実施することが可能である。
(3)トリガスイッチによる眼振解析
図2及び図7(b)に示すように、例えば被験者Mが睡眠中にめまい発作を患い、途中で起きたような場合には、被験者Mがめまい発作を自覚していることを、トリガスイッチ25をオン操作することによりトリガ信号を記録するようにしている。
これにより、睡眠中にめまい発作が起きた場合でも、トリガ信号の存在により、睡眠中にめまい発作が発生した状況にて眼振解析を実施することが可能である。
(4)介護、在宅医療への適用
本実施の形態では、眼振記録装置20は、図2に示すように、携帯型情報記録器30に各種センサ21〜24及びトリガスイッチ25を接続したものであるため、装置自体が小型で軽量である。このため、寝たきりの患者や在宅医療にある患者にも適用することが可能であり、病床往診にて高度な眼振検査を患者に提供することが可能である。
(2) nystagmus analysis during REM sleep As shown in FIG. 4 and FIG. 7 (a), the REM sleep region is calculated by the REM sleep analysis which is one of the sleep analyses. Analysis can be performed.
(3) Nystagmus analysis by trigger switch As shown in FIG. 2 and FIG. 7B, for example, when the subject M suffers from a dizzy seizure during sleep and wakes up in the middle, the subject M performs a dizzy seizure. The trigger signal is recorded by turning on the trigger switch 25 to recognize that it is aware.
Thereby, even when a vertigo seizure occurs during sleep, it is possible to perform nystagmus analysis in a situation where the vertigo seizure occurs during sleep due to the presence of the trigger signal.
(4) Application to nursing care and home medical care In this embodiment, the nystagmus recording device 20 has various sensors 21 to 24 and a trigger switch 25 connected to a portable information recorder 30 as shown in FIG. Therefore, the device itself is small and lightweight. For this reason, it can be applied to a bedridden patient or a patient in home medical care, and it is possible to provide a patient with an advanced nystagmus examination in a bed visit.
