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?
Subject volunteered to participate in the experiment and signed informed consent
Age ≥ 65 years old, no gender limit;
Diagnosis of stroke patients;
No other major cardiovascular diseases
Subject's poor compliance
Subjects with skin allergies
Those who do not meet the criteria for diagnosis and inclusion;
People with severe consciousness disorders, severe dementia, speech disorders, etc. who are unable to communicate and describe the disease;
Parallel
Observation Group
DeviceOn the basis of myoelectric biofeedback treatment in the control group, the control group was trained alternately in each muscle group (triangle muscle, triceps brachii muscle group and forearm extensor muscle group). For example,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.
Effect of myoelectric biofeedback therapy on upper limb function in elderly patients with cerebral infarction
Fugl-Meyer Functional Score (FMA) is evaluated, and the higher the score, the stronger the motor function.
Influence on stroke quality of life in elderly patients with cerebral infarction
Assessment of Daily Living Ability Scale (ADL)is evaluated,The higher the score, the greater the independence of life.
