Brief summary: The purpose of this clinical trial is to investigate the effect of myoelectric biofeedback therapy on upper limb function in elderly patients with cerebral infarction, and to analyze the adjustment of stroke condition and quality of life.The main questions it aims to answer are:

1. Does myoelectric biofeedback therapy promote the restoration of upper limb function in elderly patients with cerebral infarction?
2. What medical problems do participants have with myoelectric biofeedback therapy?

Detailed description: We divided the participants into control group and observation group using simple random method.We will number the numbers according to the order of inclusion: then from any row in the random number table as a starting point, we will get a random number sequentially from its series of numbers, paired with the included case number, and list the random distribution table.The control group was represented by odd numbers of random tables and even numbers by observation groups.The probability of being included in the control group and the observation group were 50% respectively.The control group underwent comprehensive rehabilitation training, and the observation group conducted myoelectric biofeedback treatment on the basis of the control group.

Control group treatment plan

1. After stroke, medical staff should adjust the position of the patient every 2 hours, so that the patient's position is adjusted between the healthy side position and other positions, and provide the patient with soft pillow limit.
2. Passive training, in the initial physical disability of the patient after treatment by the rehabilitation therapist to provide passive training for the patient, specifically by the rehabilitation therapist on the affected side joint.
3. Anti-spasmodic activities, through the patient's activity training to avoid spastic symptoms, help the patient to change the posture to a healthy side position before the training begins.
4. At the beginning of the training, the rehabilitation therapist places both hands under the patient's shoulder blades, so that the patient's shoulders and shoulder blades are stretched forward to help the patient stay seated.In addition, the patient is provided with Bobas handshake training to maintain the trunk forward tilt position during the training process, maintaining the center of gravity below, helping the patient to stay seated for a long time for balance training.
5. Active training, the rehabilitation therapist instructs the patient to put the hand on the prepared cushion in advance, and then let the patient use both upper limbs to stretch the fixed elastic band to implement impedance training.After the above activities can be completed, you can try to implement refined operations, including threading and other activities that require high hand activities.After the patient's upper limb function has been restored, he or she can conduct autonomous life ability training under the guidance of a rehabilitation therapist, including basic activities such as getting up and washing.The pre-active training training time is maintained at about 0.5 h, and the maximum number of training times in one day is 3 times, and the intensity of training can be increased appropriately after the patient's physical condition has recovered.

Observation group treatment plan

The observation group carried out myoelectric biofeedback therapy on the basis of the control group:

After disinfection of the triangular, triceps and extensor muscles of the patient, the feedback electrode was attached to the area. The stimulation frequency was set at 50 Hz and the stimulation pulse width was set at 200 μs.During treatment, the patient is instructed to listen carefully to the device's password, drive the affected limb according to the specific password, and then perform tension and relaxation training.For each muscle group, the training time of each muscle group is about 0.5 h, 1 / d.In the later stage of treatment, the training intensity can be increased appropriately, so that the patient can carry out weight lifting during the feedback treatment, and listen to the password issued by the device to carry out muscle strength exercise.
