prompting the user to relax for 3s through a prompting module 7, and acquiring a myoelectricity value V in a resting state EMGMIN (generally the myoelectric value in the resting state is lower than 5 uV). And then the prompting module 7 prompts the user to contract for 3s and collects the maximum myoelectricity value V of the user EMGMAX (contractile myoelectric values).
And adjusting the electrical stimulation intensity adjusting module 8 to control the electrical stimulation output intensity to enable the target muscle (or joint) to achieve the expected effect, wherein the current electrical stimulation intensity is the maximum electrical stimulation output intensity, and the current myoelectric signal is the electrical contraction myoelectric value. And then stopping electric stimulation output, carrying out myoelectricity acquisition, and outputting electric stimulation according to the myoelectricity value and the figure 6.
Wherein the maximum limit value I of the intensity of the electrical stimulation output during the treatment process max The electric stimulation intensity adjusting module 8 is arranged for a user, and the processor 3 is used for adjusting the electric stimulation intensity according to the size V of the collected electromyographic signals EMG Proportional output of electrical stimulation intensity I es . When V is EMG When 0, I es 0, namely the electromyographic signal stops the electric stimulation; when V is EMG Greater than 0 and less than myoelectric threshold, I es Micro electrical stimulation is carried out with weak intensity, so as to achieve the effect of promoting movement; when V is EMG Above the myoelectric threshold, I es From V EMG And controlling the proportion, namely controlling the electrical stimulation output intensity by the strength of the electromyographic signal.
When the myoelectric value V EMG =0, electrical stimulation output Ies =0; when the myoelectric value V EMG >0 and<resting muscle electrical value V EMGMIN When the patient feels the pain, the electric stimulation intensity Ies reaches the movement promotion (the patient feels light touch and flap, and the muscle contraction cannot be seen when the current is small) with weak intensity (5 mA); when the myoelectric value V EMG At rest muscle electricity value and incomeWhen the contractile muscle electrical values are different, the electrical stimulation intensity Ies is converted in the equal proportion of the weak intensity and the maximum intensity, and the scale factor K = (I maximum electrical stimulation intensity-I weak intensity)/(V contractile muscle electrical value-V resting muscle electrical value).
For example, when the wrist joint is relaxed, the extension angle of the wrist joint is 0, and the myoelectric signal is the resting myoelectric value. The electrical stimulation output intensity is adjusted by the electrical stimulation intensity adjusting module 8 to extend the wrist to an expected angle, the electrical stimulation output intensity at the moment is the maximum electrical stimulation output intensity in the power-assisted electrical stimulation mode, and the myoelectric signal at the moment is the electrical contraction value. And then, the user can control the electrical stimulation output according to the subjective movement consciousness of the user, when the user wants to move, the wrist joint is stretched, and the system outputs the corresponding electrical stimulation intensity according to the collected myoelectric value. When the user does not want to exercise, the wrist joint is relaxed, the myoelectric value is lower than the resting myoelectric value and even is 0, and the electrical stimulation is changed into weak intensity and even stops. Preventing muscle fatigue and muscle injury.
In a preferred embodiment, the electrical stimulation intensity adjusting module 8 is a rotary encoder.
The rotary encoder is used as the electrical stimulation intensity adjusting module 8, so that the electrical stimulation intensity can be adjusted more conveniently by a user in the control process. Typically, clockwise rotation increases the electrical stimulation output intensity and counterclockwise rotation decreases the electrical stimulation output intensity.
In addition, the electrical stimulation device also comprises a starting button which is a touch switch, and when a user presses the touch switch for 3s (the time can be set by software), the system is started. The tact switch 3s is pressed again (this time can be set by software), and the system is shut down.
The multifunctional touch screen also comprises a functional switch which is a plurality of touch switches and is mainly used for interaction, up-down, left-right and confirmation/deletion between a user and the display screen.
The self-locking push-pull switch is also included and is used for locking the selection and the output of the current treatment scheme. When the self-locking push-pull switch is in effect, all buttons and encoders except the power-on button are not responded. The application scene is that the electrical stimulation device is put in a pocket, a backpack or hung on the neck under the working state, and the electrical stimulation output of the locking is not influenced by the mistaken touch, the limb activity and the like of a user.
