Description
Technical field
The present invention relates to biomedical engineering research field, concretely relates to one kind based on vestibule electricity irritation and head
The vestibular function detection means of motion tracking.
Background technology
Vestibular system has stable optical and stablizes the dual function of vertical balanced, and these effects are walked by originating from fan
Organ eventually terminates at the motor neuron of eye, neck, trunk and limb muscle and obtains.The meeting when vestibular function is undermined
There is disequilibrium and dizziness, therefore the quantitative test of vestibular function has important effect in prevention vestibular dysfunction.
Ideally detect that the integrity of vestibular function needs to detect that vestibulo-ocular reflex and vestibule balance control access
Integrity.The angular acceleration and linear acceleration of head is the enough stimulations for exciting vestibule cell.However, applying a real head
Portion's acceleration come to test vestibule path be very difficult because having incoming extensive of somatesthesia in muscle, joint and skin
Activate and this can cause powerful postural response.Vestibule electricity irritation makes the incoming pure stimulation of vestibule, makes these direct
Somatesthesia reaction be not activated.And vestibule electricity irritation is technically very simple, safe, and experimenter can be good at standing.He
Be particular in that it can be provided separately a pure vestibular stimulation to test vestibular function to lost.When human body is subject to
During vestibule electricity irritation head occur acceleration can by measure angular acceleration size and human body head restore balance when
Between assessing vestibular function.And people has short-term and long-term acclimatization to vestibule electricity irritation, so good balanced capacity and fortune
Dynamic controling power can be improved by training.
The appearance of vestibular function examination technology and the history of existing decades is developed so far, as vestibular nervous system is organized
Structure, function are extremely complex, so vestibular function detection technique is made slow progress, use air, head position property before
The methods such as nystagmus.Also there is no a kind of device of convenient, fast, effective detection vestibular function.
Therefore, a kind of exigence device in this area realizes the one or more in following functions：
The vestibule electricity irritation of-Noninvasive, improve measured before detection front yard function when comfort level；
- by applying vestibule electricity irritation, change human body head acceleration, detect, train and study vestibular function.
The content of the invention
It is an object of the invention to provide a kind of device of Noninvasive vestibular function detection, realizes convenient, fast, effective
The detection of vestibular function, is that vestibular function selects training, prevention vestibular dysfunction and Study of Vestibular Function etc. to provide foundation.
The vestibular function detection means tracked based on vestibule electricity irritation and head movement of the present invention is included：Vestibule electricity irritation
Device, head pose measurement apparatus and control computer.
Vestibule electrical stimulation device includes the helmet, DC constant flowing power, control circuit, wire and electrode slice.The device passes through
After picking up the ears to forehead, left and right temple or two, mastoid process carries out electricity irritation, induces three dimensions head movement.Current output terminal passes through
After the forehead of electrode slice and people, left and right temple or ear, mastoid process is coupled, and realizes the conducting of electric current and human body.
Head pose measurement apparatus include three-dimensional attitude sensor, and in the device, three-dimensional attitude sensor is fixed on the helmet
On, the connection of three-dimensional attitude sensor and control computer is realized by bluetooth, receives measured's attitudes vibration signal.
Control computer is connected with vestibule electrical stimulation device, head pose measurement apparatus.By the spy in control computer
Determine stimulating current type, intensity and stimulation time that software can set vestibule electricity irritation.Meanwhile, control computer receives head
The signal of attitude measuring, can show the numerical value of stimulating current type, intensity and the stimulation time of electrical stimulation device in real time
Change with the head pose of head pose measurement apparatus.
Beneficial effects of the present invention are as follows：
The vestibular function detection means tracked based on vestibule electricity irritation and head movement of present invention design can be to tested
Person's vestibular apparatuies carry out the 3 d pose change of effective stimuluss and detection human body head.
As can be seen here, the present invention can provide a kind of Noninvasive vestibule detection means, improve by the comfort level of side person,
Create a kind of convenient, fast, effective vestibule and detect instrument.It is further useful for preventing vestibular dysfunction, vestibular function
Related training, improve vestibular function, strengthen balanced capacity and improve motor control, reduce due to vestibular function caused thing
Therefore.

Specific embodiment
As shown in figure 1, the vestibular function for being tracked based on vestibule electricity irritation and head movement according to an embodiment of the invention
Detection means includes：Vestibule electrical stimulation device 1, head pose measurement apparatus 6 and control computer 2
According to one embodiment of present invention, as depicted in figs. 1 and 2, vestibule electrical stimulation device 1, including the helmet 5, direct current
Constant current source 7, control circuit, 3, five electrode slices 4 of wire etc., Jing after electrode slice 4 is picked up the ears to forehead, temple or two, mastoid process is entered
The controllable galvanic stimulation of row, for changing the input signal of human vestibule organ.Control can be set by controlling calculating 2
Circuit produces polytype stimulating current, and can set real-time stimulating current direction and amplitude.Vestibule electrical stimulation device
Positive-negative output end passes through electrode slice 4 and body-coupled respectively, for the conducting of stimulating current and human body, and makes the electric current for passing through be
Setting value.Head pose measurement apparatus 6 are contained within three-dimensional attitude sensor, can obtain the letter of head pose change in real time
Number, processed to control computer 2 by Bluetooth transmission.Vestibule electrical stimulation device and head pose measurement apparatus are finally integrated
It is placed on the helmet.
The device detects the head pose change of measured, is a kind of vestibule of Noninvasive by inducing vestibular illusion
Function detection device, can be used for the detection of vestibular function, the choice training of vestibular function and the research of vestibular function.
The detection of embodiment vestibular function
This device can be used for the detection of vestibular function.During use, measured wears the helmet 5, and body keeps standing.Vestibule electricity
The electrode slice of stimulating apparatus 1 is affixed on mastoid process after bilateral ear respectively, and is fully contacted which.The control vestibule electricity thorn of control computer 2
The stimulating current type of excitation device 1, intensity and stimulation time, stimulate to measured.Normal person in vestibule electricity irritation, meeting
Incline to the anode of electricity irritation；But the patient of some vestibular dysfunctions lacks does not have this phenomenon, or inclined amplitude is obvious
It is less than normal.The head pose of measured changes by the three-dimensional attitude sensor in the head pose measurement apparatus 6 being fixed on the helmet
Real time record, 2 real-time reception three-dimensional attitude sensor data of control computer show after data processing in real time and preserve.
It should be appreciated that only illustrating rather than to the description carried out by the present invention in described above and explanation limited
, and on the premise of the present invention limited without departing from such as appended claims, above-described embodiment can be carried out various
Change, deform, and/or correct.
