The benefits of electrotherapy are that it can treat certain diseases, such as inflammation, pain, edema, etc.; the disadvantages can cause muscle contraction, headache, etc.
1. Benefits: Different types of electric current have different main physiological effects on the human body, and electrotherapy can treat inflammation, injury, pain relief, edema, etc.
Direct current is often used for drug ionization; low and medium frequency current stimulation is often used for neuromuscular diseases, such as injury, inflammation, etc.; high-frequency electrical energy to relieve inflammation and edema, the human body produces thermal effects and thermal external effect to promote circulation; electrostatic commonly used in neurosis, menopausal syndrome, etc..
2. The bad side: different types of electrotherapy adverse reactions vary.
(1) Decrease in muscle nerve sensitivity: If certain localized electrotherapy is applied for a long time, it may lead to decrease in muscle nerve sensitivity.
(2) Endocrine disorders: when electrotherapy acts on the glandular area, it may have an effect on the human endocrine system, and long-term application may lead to endocrine disorders.
(3) Abnormal changes in nerve rhythm: long-term electrotherapy, especially head electrotherapy, may stimulate the nerves and produce nerve excitation, resulting in abnormal changes in nerve rhythm, patients may experience dizziness, headache, nausea and other symptoms.
It is recommended that patients under the guidance of a professional doctor to carry out electrotherapy, do not blindly self electrotherapy, to avoid the adverse consequences.
