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.

Myasthenia gravis, repetitive nerve electrical stimulation showed that when low-frequency electrical stimulation (3 ~ 5Hz), the amplitude decreased by more than 15%; When high frequency electrical stimulation (above 10Hz), the amplitude decreases by more than 30%. Repeated electrical stimulation examination is the main examination method to detect neuromuscular junction diseases. This examination should be carried out 12-18h after stopping neostigmine, otherwise false negative results can occur. 90% of myasthenia gravis patients were positive under low-frequency stimulation, which was related to the severity of the disease.
