Verification examples

1. Checking of myoelectric biofeedback signal display system

The feedback signal of the invention is calibrated and detected according to the industry standard YY 0896-2013 'requirements specially for myoelectricity and induced response equipment safety'. Before the electromyographic biofeedback instrument is used for detection, whether the precision meets the requirement or not needs to be determined, and then other technical indexes can be measured by displaying the instrument. The display system is verified by using a standard low frequency signal generator and an AC millivoltmeter.

Firstly, a sinusoidal signal is added to the input end of the electromyographic biofeedback instrument through a balance attenuator, the frequency of the sinusoidal signal is selected as the center, the frequency is 500Hz, then the voltage amplitude of the signal input is adjusted, the reading of a display system of a detected instrument is 10% and 90% of each gear, and the reading of an alternating-current millivoltmeter is observed, wherein the error between the reading and the display value of a detected sample is required to be not more than 10%. When the signal generator was adjusted so that the test instrument displayed values of 1 μ V and 9 μ V (via a 1000-fold attenuator) for the 10m V gear, the millivoltmeter readings were observed to within 0.1m V and 0.9m V, thus indicating that the instrument was accurate.

3. Verification of feedback signals

When the input amount is changed by 0.2V, the display system is significantly changed. Through the observation of display indication, when the change of the electromyographic signals shows that the change is 0.2 muV through the display system, the feedback system can also change, and the requirements are met.

3. Verification of clinical trial effect

80 patients with shoulder joint subluxation after apoplexy and hemiplegia are treated in 12 months to 2020 months in 2018, and are randomly divided into two groups of 40 patients. Observing 20 men and 20 women in the group; mean age (54.23 ± 4.25) years. Reference group 20 men and 20 women; mean age (53.27 ± 4.14) years. Compared with the general data of two groups, the difference has no statistical significance (P is more than 0.05) and is comparable.

Inclusion criteria were: firstly, the diagnosis is confirmed through the examination of brain CT and the like; ② the health care wine has normal cognitive function and stable vital signs; third, the patient and the family sign the informed consent.

Exclusion criteria: the disease condition fluctuates greatly; ② combining severe infection of the whole body; ③ the bleeding tendency is serious; and fourthly, the combined visceral functions of diabetes, osteoporosis or liver, kidney, heart and lung and the like are complicated.

The method comprises the following steps: all patients are guided to take the blood sugar reducing drugs, the blood fat reducing drugs and the blood pressure reducing drugs on time and in quantity, and the stability of vital signs is ensured. Simultaneously provides moxibustion therapy, operation therapy, electric acupuncture therapy and exercise therapy for patients. The shoulder rest reconstruction treatment system with the treatment function is used for implementing electromyographic biofeedback electrical stimulation treatment on a patient, the patient is advised to observe an electromyographic signal on a display screen before treatment, the muscle strength of the patient during target action is judged according to the signal curve, and relaxation or target action is kept according to an instruction sent by an instrument. The reference group adopts moxibustion therapy. The observation group adopts a shoulder support therapy with a treatment function: before treatment is carried out on a patient, the skin of a treatment part is disinfected by using an alcohol cotton ball, then electrodes are pasted on the skin surfaces of the supraspinatus and deltoid muscle abdomens of the patient, then leads and the electrodes are connected, and treatment parameters are selected according to the actual condition of the patient. After the treatment, myoelectric signals generated by muscle contraction are displayed on a display screen, after the instrument sends an instruction, a clinician encourages and guides a patient to improve the target muscle contraction strength to the maximum extent, a threshold value is set according to the myoelectric signals collected by the system record, and the system can generate electric stimulation to the patient after the threshold value is reached, so that the patient can complete target actions. The patient should either fully relax the muscles or try to maintain the target motion according to the system instructions. In the training process, the patient should be guided to control the shoulder joint lifting movement, abduction movement and anteflexion movement in time through feedback signals, the training time is 30 min/time, the treatment is 5 times/week, and the treatment lasts for 2 weeks.

Observation indexes are as follows: the motor function of the upper limbs, the degree of neurological deficit and the recovery of daily life capacity of the two groups of patients were compared. Evaluating the motor function and neurological impairment degree of the upper limb of the affected side of the patient by using a Fugl-Meyer rating scale; assessing the daily living capacity of the patient by applying the Barthel index; the more ideal the patient's upper limb movement and daily living ability is restored, the higher each score.

Statistical treatment: processing data by using SPSS 22.0 software; the measured data are expressed as (x +/-s) and a t test is adopted; p < 0.05 is statistically significant.

TABLE 1 comparison of Fugl-Meyer and Barthel scores before and after treatment (x. + -. s, min.) for two groups of patients

As a result: comparison of Fugl-Meyer and Barthel scores before and after treatment in two groups of patients: the difference between the Fugl-Meyer and Barthel scores before treatment in the two groups is not statistically significant (P is more than 0.05); Fugl-Meye and Barthel scores were higher in the observation group than in the reference group after treatment, and the difference was statistically significant (P < 0.05).
