The first user may be a user who needs to receive electrical stimulation of the tongue nerve, such as a PD patient. The particular state may be an OFF state or the like that characterizes the state in which the first user's athletic symptom onset is located. The OFF state is the motor symptom onset state of the PD patient. Typically, when a first user gives symptoms of movement that can be indicative of a particular state, such as tremor and/or bradykinesia, the first user may be determined to be in the particular state.

The MD sends the slope parameter to a microcontroller (controller) of the electric stimulation device through a communication module (wireless communication module) of the electric stimulation device, so that the microcontroller controls a constant current source pulse generating circuit (pulse generating circuit) to generate a pulse signal according to the slope parameter, and the electrode array is controlled to send out electric stimulation to electrically stimulate the lingual nerve of the first user. The MD may be held by a second user, where the second user may include a first user and a doctor of the first user, etc. needs to learn the state of the first user, and the first user may be a PD patient, etc. needs to receive electrical stimulation of the lingual nerve. MD may be, but is not limited to, various notebook computers, smartphones, tablet computers, and portable wearable devices.
As one embodiment, the controller adjusts the pulse parameter down when it is identified that the slope parameter is negative (less than 0) and the absolute value of the slope parameter is greater than the first adjustment threshold; when the slope parameter is identified as positive (a value greater than 0) and the absolute value of the slope parameter is greater than the second adjustment threshold, the pulse parameter is turned up.
The pulse parameters may include parameters such as pulse amplitude and/or pulse duty cycle. The controller may adjust the pulse parameters down by adjusting the pulse amplitude and/or the pulse duty cycle and adjust the pulse parameters up by adjusting the pulse amplitude and/or the pulse duty cycle.
The first adjustment threshold and the second adjustment threshold are positive values respectively. The first adjustment threshold and the second adjustment threshold may be set according to a duration feature of the monitoring period and a specific state of the first user, for example, if the monitoring period is 4 weeks, the first adjustment threshold may be set to 6 hours, and the second adjustment threshold may be set to 4 hours.
In this embodiment, the controller may obtain, from the terminal, a slope parameter corresponding to a specific state of the first user in the monitoring period, adaptively adjust an electrical stimulation device that electrically stimulates the tongue nerve of the first user according to the slope parameter that characterizes a trend of a change in a duration of the first user in the specific state in each statistics period of the monitoring period, so that a stimulation behavior sent by the electrical stimulation device of the tongue nerve may be adjusted according to a specific state characteristic of the first user in the monitoring period, so that the corresponding stimulation behavior is more targeted, a pulse parameter adjustment process of the electrical stimulation device may be simplified, and instantaneity of adjusting pulse parameters may be improved.
As one embodiment, the pulse parameters include pulse amplitude and pulse duty cycle;

the controller increases the pulse amplitude by a first set proportion; and/or, the pulse duty ratio is adjusted to be larger by a second set proportion so as to adjust the pulse parameter.
The first setting proportion and the second setting proportion can be set according to the configuration characteristics of the electric stimulation device of the lingual nerve, and the values of the first setting proportion and the second setting proportion can be the same or different, for example, if the pulse amplitude of the electric stimulation device is reduced by the first setting proportion or the pulse duty ratio of the electric stimulation device is reduced by the second setting proportion to realize the reduction of corresponding pulse parameters, the first setting proportion and the second setting proportion can be set to be 5% respectively.
As one embodiment, the controller maintains the pulse parameter unchanged upon identifying an opposite number of the slope parameter being less than or equal to the second adjustment threshold and greater than or equal to the first adjustment threshold.
If the slope parameter is smaller than or equal to the second adjustment threshold value and is larger than or equal to the opposite number of the first adjustment threshold value, the current pulse parameter of the electric stimulation device is the pulse parameter required by the tongue nerve of the first user to receive the corresponding electric stimulation, and the current pulse parameter can be kept unchanged without relevant adjustment.
As an example, if the first setting ratio and the second setting ratio are set to 5% respectively, b OFF Representing a slope parameter, A1 representing a first adjustment threshold, A2 representing a second adjustment threshold, and the symbol "||" representing an absolute value; the above-mentioned pulse parameter adjustment process may be shown in fig. 6, and includes:

if b OFF > 0 and |b OFF The pulse amplitude is increased by 5% or the pulse duty ratio is increased by 5% by I > A2;
if none of the above conditions is satisfied (i.e., b OFF < 0 and |b OFF I > A1 and b OFF > 0 and |b OFF Both of i > A2 are not true), keeping the pulse parameters unchanged.
In one embodiment, the terminal obtains the statistical duration of the first user in a specific state in a plurality of statistical periods, and determines the slope parameter according to the statistical duration of each statistical period. The monitoring period includes a plurality of statistical periods.
Specifically, the unit duration of each time the first user is in a specific state in each statistics period can be obtained, and the sum of the unit durations of the statistics periods is determined as the statistics duration of the first user in the corresponding statistics period.
According to the embodiment, a curve can be drawn according to the statistical duration of each statistical period, so that the slope parameter corresponding to the specific state of the first user in the monitoring period can be determined according to the curve. Specifically, the trend parameter corresponding to the curve with the ascending trend is greater than 0, the trend parameter corresponding to the curve with the descending trend is less than 0, and the trend parameter corresponding to the leveled curve is equal to 0.
As an example, if the specific state is an OFF state, the monitoring period is one month, each statistical period is each week in one month, and a curve drawn according to the statistical duration of each statistical period may be shown with reference to fig. 7.
As an embodiment, the process of determining the slope parameter by the terminal according to the statistical duration of each statistical period may include:
