Does electric stimulation have side effects in the treatment of scapulohumeral periarthritis?

Electrical stimulation therapy is divided into low frequency, medium frequency and high frequency. It is mainly used to treat soft tissue diseases, such as scapulohumeral periarthritis, lumbar spondylosis and cervical spondylosis. Low frequency electrotherapy can effectively prevent muscle atrophy and promote nerve reinnervation; Medium frequency electrotherapy is used for deep soft tissue pain; High frequency electrotherapy has radiation, the deepest action position and the strongest detumescence effect. Weak electrical stimulation has no obvious side effects on the human body. The electric field acts on the human tissue, which can promote the metabolism of inflammatory substances and pain causing substances and promote blood circulation, so as to inhibit pain and eliminate swelling. Electric stimulation therapy can also be used for drug iontophoresis. Analgesic drugs and anti-inflammatory drugs are introduced subcutaneously through electric current to treat skin and soft tissue inflammatory diseases.

Clinically, moderate intensity electrical stimulation from the central end of one side of the vagus nerve can generally lead to apnea. This is mainly due to the reflex inhibition of inspiratory action after lung expansion caused by lung stretch reflex, or the reflex inhibition of respiratory action after lung shrinkage enhances inspiratory action. When these two kinds of reflex are transmitted to human nerve fibers, they will excite the vagus nerve and produce afferent impulse, which will lead to the change of respiratory movement to the respiratory center, Because electrical stimulation causes afferent impulses, which are continuously transmitted to the respiratory center and inhibit respiratory movement, apnea will occur.
