In existing technology, implantation medical equipment typically utilizes battery to power, and sends the boost pulse of characteristic frequency, specific target spot carries out long-time stimulus, thus improves the symptom of patient.This stimulus modelity is referred to as constant frequency stimulus modelity.Under constant frequency stimulus modelity, the stimulation time of target spot is typically lasted for more than several days by single-frequency, some months, the most several years.But from the point of view of clinic, existing stimulating method is to the poor effect of some symptom and can produce certain adaptability.Such as, for the deep brain stimulation of parkinson symptom, under the stimulation of constant frequency, dysarthria, gait are freezed, the non-motor symptoms such as unusual fluctuation improves little.It addition, according to the nerve electric stimulation Couple herbs to anti-Parkinson and epileptic, patient, under the stimulation of constant frequency, easily produces adaptability to stimulating so that therapeutic effect is deteriorated, and is similarly to reusing the Drug resistance that medicine produces for a long time.
And, stimulating electrode (comprise or do not comprise extension lead), pulse generator are all implanted into the human body by the using method of implantation medical equipment typically by operation at present, treat a few time-of-week of postoperative recovery, then open pulse generator and stimulate, observe and assess effect of stimulation.But there is symptom and improve inconspicuous or without improvement situation in some patients, now needs to take out implant.In practice for observing and assessment effect of stimulation, it is chronically implanted the pulse generator of use and extension lead not necessarily, and patient is caused bigger physical impairment by the operation technique needed for implanting two assemblies.Therefore, for this some patients, current procedure pattern there are two drawbacks, and one is the waste of apparatus, and two is the excessive use of operation.
In order to avoid above-mentioned drawback, it is thus proposed that use electric pulse stimulation test system first patient observed and assess.Such as, first only at implantable stimulation electrode in the patient, then this stimulating electrode and an electric pulse stimulation are tested system electrical connection.Tested by this electric pulse stimulation test system, and observe and assess to determine that this patient is if appropriate for electrical stimulating therapy.But, existing electric pulse stimulation test system is only capable of testing the constant frequency stimulus modelity of single-frequency.

Case 2
Disturbances in patients with Parkinson disease Y suffers from body rigidity symptom and gait freezes symptom, and uses electric pulse stimulation to treat first.
Symptom according to patient Y selects different constant frequency stimulus frequency, finds that the body rigidity symptom of patient Y is significantly improved under the constant frequency of 130 hertz stimulates, and the gait of patient Y is freezed symptom and is improved under the constant frequency of 80 hertz stimulates.
The frequency conversion stimulation pulse signal using 130 hertz and 80 hertz carries out stimulation therapy to patient Y.The time accounting setting two kinds of frequencies is 50%, and the electric stimulation pulse string of each frequency duration in each burst periods is 20 seconds.Observe the improvement situation of patients symptomatic, find that gait is freezed to be significantly improved, but body rigidity improves undesirable.Further, regulating 130 hertz frequency accountings is 60%, and 80 hertz frequency accountings are 40%, then observes the improvement situation of patient, finds that gait is freezed all to be significantly improved with body rigidity.
Case 3
Disturbances in patients with Parkinson disease Z cardinal symptom body rigidity, has serious gait to freeze symptom simultaneously.
To frequency 130Hz, amplitude 2.7V, pulse width 60 μ s on the left of patient Z applying；Right side frequency 130Hz, amplitude 1.7V, the permanent frequency stimulation of pulse width 60 μ s, its stiff symptom be improved significantly, gait freezes exacerbation of symptoms.The stimulus frequency of patient is reduced to 60Hz, i.e. left side frequency 60Hz, amplitude 2.7V, pulse width 60 μ s；Right side frequency 60Hz, amplitude 1.7V, the constant frequency of pulse width 60 μ s stimulates, and this patient's gait is freezed symptom and improved substantially, but stiff severity of symptoms.The Frequency being adjusted to 60&130Hz stimulates, i.e. left side frequency 60&130Hz, amplitude 2.7V, pulse width 60 μ s；Right side frequency 60&130Hz, amplitude 2.7V, pulse width 60 μ s, one of them cycle 50s, the 60Hz comprising 20s stimulates and the 130Hz of 30s stimulates.The spasticity of patient be improved significantly, and gait freeze symptom be improved significantly.The following is gait evaluation table before and after patient's frequency conversion stimulates.
Before and after table 2 frequency conversion stimulates, gait evaluation contrasts
| Constant frequency stimulates 130Hz | Frequency conversion stimulates 60Hz&130Hz | |
| Start-up time (s) | 20 | 3 |
| Turning time (s) | 14 | 3 |
| Speed (m/s) | 0.75 | 0.83 |
| Step-length (m) | 0.40 | 0.42 |
| FOG-Q score | 20 | 8 |
| UPDRS III gait score (the 30th) (item 30) | 2 | 0 |
From upper table it will be seen that frequency conversion stimulate compare constant frequency stimulate, patient's start-up time, turn the dead time significantly reduce, gait freeze be improved significantly.
It addition, those skilled in the art can also do other changes in spirit of the present invention, these changes done according to present invention spirit, all should be included in scope of the present invention.
