Between accounting, reduce the time accounting of the corresponding frequency of stimulation of other symptoms, reach balanced until making the symptom of patient improve.
In existing stimulus modality, stimulus waveform, which is the constant frequency of upper frequency, to stimulate, and the constant frequency is to patient
Symptom have an improvement, but be inevitably attached to some ill symptoms, and patient be easy to generate the stimulation of this constant frequency it is suitable
Ying Xing.The present invention is by introducing frequency conversion stimulation pulse signal, under the premise of ensureing to the effect of stimulation of patient, can improve or
Eliminate subsidiary symptom.
For example, in clinic, disturbances in patients with Parkinson disease implantation brain pacemaker stimulates its subthalamic nuclei, can significantly improve it
It trembles, the symptoms such as body is stiff.However, in the prior art, the stimulation to subthalamic nuclei is the stimulation of constant frequency.For a long time
Stimulation after, some patientss will produce gait freeze, dysarthrosis, the subsidiary symptom such as unusual fluctuation.In addition, long-time single-frequency
Stimulation, such as 100 hertz make patient be easy to generate adaptability to this stimulation, are similar to adaptability of the patient to drug, stimulation effect
Fruit is deteriorated.
In some clinical cases, frequency conversion stimulus modality is for treating disturbances in patients with Parkinson disease.It is clinical research shows that variable-frequency electric
Stimulation can improve Parkinson motor symptoms, such as tremble or/and body be stiff, while improve Parkinson non-athletic disease
Shape, if gait is freezed, dysarthrosis is mobile etc., and can avoid adaptability caused by constant frequency.In addition, studies have shown that the change
Frequency stimulating system for move relevant Other diseases such as myodystony, and with cognition, the relevant neurogenic disease of psychology
Such as depression, habituation, there is fine curative effect.
The present invention has been used to improve disturbances in patients with Parkinson disease due to subsidiary symptom and adaptation caused by long term constant frequency stimulation
Property.It is the real case of the application present invention below.

Observe the reflection of patient X.Patient X under the stimulation of 60Hz, the state of dysarthrosis be improved significantly.Using 60 hertz and
130 hertz of frequency conversion stimulation pulse signal carries out stimulation therapy to patient X.The time accounting for setting two kinds of frequencies is 50%,
The electric stimulation pulse string of each frequency duration in each burst periods is 10 seconds.Through stimulation after a period of time,
The improvement degree of the symptom of patient X is observed, the situation of dysarthrosis is significantly improved.Frequency conversion stimulation through the invention,
Under the premise of ensureing therapeutic effect, the minute symptom of patient is improved.It is patient below to be stimulated and become with common constant frequency
Stimulate obtained sounding effect to compare frequently.
1 constant frequency of table stimulates the phonation efficiency with frequency conversion stimulation to compare
Case 2

It treats.
Different constant frequency frequency of stimulation is selected according to the symptom of patient Y, finds the patient Y under 130 hertz of constant frequency stimulation
Body rigidity symptom be significantly improved, and the gait of patient Y freezes symptom and obtains one under the stimulation of 80 hertz of constant frequency
It is fixed to improve.
Stimulation therapy is carried out to patient Y using 130 hertz and 80 hertz of frequency conversion stimulation pulse signals.Set two kinds of frequencies
Time accounting be 50%, the electric stimulation pulse string of each frequency duration in each burst periods is 20 seconds.
The improvement situation of patient symptom is observed, it is found that gait is freezed to be significantly improved, but body rigidity improvement is undesirable.Into one
Step, it is 60% to adjust 130 hertz frequency accountings, and 80 hertz frequency accountings are 40%, then observe the improvement situation of patient, find step
State is freezed to be significantly improved with body rigidity.
Case 3
Disturbances in patients with Parkinson disease Z cardinal symptom body rigidities, while thering is serious gait to freeze symptom.
Apply left side frequency 130Hz, amplitude 2.7V, 60 μ s of pulse width to patient Z；Right side frequency 130Hz, amplitude
1.7V, the permanent frequency stimulation of 60 μ s of pulse width, stiff symptom be improved significantly, gait freezes exacerbation of symptoms.By patient
Frequency of stimulation be reduced to 60Hz, i.e. left side frequency 60Hz, amplitude 2.7V, 60 μ s of pulse width；Right side frequency 60Hz, amplitude
The constant frequency of 1.7V, 60 μ s of pulse width stimulate, which, which freezes symptom, improves obviously, but stiff symptom deteriorates.It is adjusted to
The Frequency of 60＆130Hz stimulates, i.e. left side frequency 60＆130Hz, amplitude 2.7V, 60 μ s of pulse width；Right side frequency 60＆
130Hz, amplitude 2.7V, pulse width 60 μ s, one of them period 50s, including the 60Hz stimulations of 20s and the 130Hz of 30s are pierced
Swash.The spasticity of patient be improved significantly, and gait freeze symptom be improved significantly.It is before patient's frequency conversion stimulates below
Gait evaluation table afterwards.
The front and back gait evaluation comparison of 2 frequency conversion of table stimulation
From upper table, it can be seen that, frequency conversion stimulation is stimulated compared to constant frequency, and patient's start-up time, the turning dead time obviously subtracts
It is few, gait freeze be improved significantly.
In addition, those skilled in the art can also do other variations in spirit of that invention, these are spiritual according to the present invention
The variation done should be all included in scope of the present invention.

The patient of symptom comprising：One testing in vitro stimulator and a test lead, and the testing in vitro stimulator includes a pulse
Module occurs, the pulse generating module at least generates frequency conversion stimulation pulse signal, which only includes three
The electric stimulation pulse string of kind different frequency, alternately stimulation forms multiple burst periods to the electric stimulation pulse string；Its feature exists
In the frequency of stimulation of the frequency conversion stimulation pulse signal is determined by following steps：
Record the primary frequency A that the patient uses constant frequency stimulation；
Make the impulse stimulation of the pulse generating module output constant frequency patient, and it is two different subsidiary bad to record the patient
The pulse frequency B that symptom is improved1And B2；And
According to formula C=A2/B1The frequency C that a correspondence uses is calculated, according to formula D=A2/B2Another pair is calculated to answer
The frequency D, described frequency B, C, D used is the frequency of stimulation of the frequency conversion stimulation pulse signal.
14. a kind of electric pulse stimulation tests system comprising：One electric pulse stimulation test device and a stimulating electrode, it is special
Sign is that the electric pulse stimulation test device is in the electric pulse stimulation test device as described in the claims 1 to 13
Any one.
