Since 198s, people have combined listening to music with synchronous current converted from music signals to treat diseases, and achieved better results than single electrotherapy, which is called music electrotherapy.
The therapeutic effect of music electrotherapy has two aspects: First, the effect of music on human body. Different musical properties, dynamics, speeds and intervals can produce different psychological or physiological reactions to human body. Music with beautiful melody, steady rhythm, slow speed and moderate intensity has the functions of relaxation, sedation and analgesia; Music with magnificent and passionate melody, powerful and passionate rhythm and strong strength can boost the spirit and excite the nerves, and can be used to exercise muscles, enhance muscle strength, prevent muscular atrophy and promote the recovery of motor function of paralyzed limbs; Music with deep and melancholy melody, slow rhythm and weak strength has sedative and hypnotic effects; Music with strong rhythm and strength can improve muscle tension and promote sports function. Second, the effect of music current on human body. Music current has dual functions of low-frequency current and medium-frequency current, but it is different from ordinary low and medium frequency electrotherapy. First of all, the effect of music current is deep, and the human body is not easy to adapt, which can not only cause muscle contraction, but also have no stimulation discomfort like low-frequency electricity; Secondly, the effect of music current on analgesia and promoting blood circulation is similar to that of low and medium frequency current, but better than that of low and medium frequency current.
treatment method: music signals (instrumental music, songs, operas) sent by records or tapes are converted into electrical signals by an acoustic-electrical converter, and then this weak electrical signal is amplified, boosted by an audio matching device, and then current is output, which is called music current. The frequency of music current is 2~7 Hz, which is an irregular sinusoidal current with mixed low and intermediate frequencies. Its frequency, waveform and amplitude change with the rhythm and intensity of music. The music electrotherapy instrument is equipped with a variety of tapes, and the machine is equipped with a tape box and a recording device. There are two pairs of headphones, one for patients to listen to music during treatment; The other one is for the operator to listen to, as a reference for adjusting the dose.
there are two kinds of electrodes: low-frequency pulse electrotherapy electrode and needle electrode. Needle electrodes are used for music electroacupuncture.
for treatment at home, the common electrode method is generally suitable. According to the patient's condition and music hobby, choose music tapes and put them in the tape box of the therapeutic instrument. The patient exposes the treatment site, takes two conductive rubber electrodes, spreads conductive glue on the electrodes, or uses water-absorbing pad electrodes, which are placed in the diseased area, pain area, nerve trunk or muscle movement point, and then fixed with a fixing belt or sandbag. Let the patient put on headphones, turn on the power supply, press the switch of the tape box, adjust the volume after listening to the music, and then connect the electrode to the wire. Adjust the current output to make the current reach the sensory threshold; If the exercise threshold dose is used, the muscle will have obvious tremor or rhythmic contraction.
the treatment time is 15~2 minutes, once a day, and 1~2 times is a course of treatment.
Music electrotherapy has a wide range of applications. Use music with strong rhythm and moderate intensity. Sensory threshold or motor threshold dose of current can cure cerebral thrombosis, myelitis, Guillain-Barre syndrome, peripheral nerve injury, etc., which can make the motor function of limbs recover quickly; Using music with beautiful melody, moderate speed and intensity and corresponding music current to treat neurasthenia and angioneurotic headache has good effects. Using music and exercise threshold current with strong sense of rhythm and brisk melody can treat myofibrositis, lumbar strain, scapulohumeral periarthritis, cervical spondylosis, rheumatoid arthritis and so on, and can get good results.
Precautions: All patients who receive low-frequency electrotherapy for the first time should be diagnosed clearly, preferably under the guidance of a doctor; For instruments with dry batteries as power supply, attention should be paid to replacing the batteries in time to ensure sufficient electricity for treatment; Instruments that use alternating current need to be connected with grounding wire, so pay attention to the safe use of electricity; Before treatment, check the instrument, so that the current output adjustment knob is set to zero to prevent the patient from being uncomfortable due to excessive current stimulation; When the electrode is coated with conductive adhesive, the thickness should be uniform. Use water-absorbing pad electrode, which should be wet and dry moderately to maintain good conductivity; The electrode should be fixed reliably to prevent the electrode from falling off during treatment; It is normal to feel ants walking, urgency and muscle tremor during treatment, so don't worry; Adjust the electric quantity, and it is appropriate to slowly increase and decrease, so as not to cause discomfort to patients; After treatment, the power should be turned off. If the instrument is not used for a long time, take out the battery in the machine to prevent the battery from leaking and damaging the instrument.
