electrotherapy
direct current therapy
Definition: It is a current with a fixed direction and intensity that does not change with time. It applies low-voltage (30~80V), low-intensity (less than 50mA) stable direct current to the human body.
Therapeutic effects: (1) Anti-inflammatory and analgesic (2) Sedative and stimulating effects (3) Larger direct current can promote the dissolution of venous thrombus (4) Promote fracture healing (5) Treatment of coronary heart disease (6) Treatment of cancer
Therapeutic dose: generally 0.05~0.10mA/cm². The maximum does not exceed 0.05mA/cm², and for children, it is 0.03~0.08mA/cm².
Indications: (1) Neurological diseases: migraine, sciatica, neurasthenia, facial nerve paralysis (2) Medical diseases: chronic gastritis, gastrointestinal spasm, hypertension, joint pain (3) Surgical diseases: lymphadenitis, postoperative adhesions (4) Gynecological diseases: amenorrhea, functional uterine bleeding (5) Orthodontic diseases: keratitis, conjunctivitis, chronic tonsillitis (6) Dermatological diseases: skin ulcers
Contraindications: Malignant hematological diseases, malignant tumors, and skin sensory disorders.
simple direct electrotherapy
Notes: (1) People who are allergic to drugs are prohibited from doing allergy tests for drugs that may cause allergies. (2) Distilled water, deionized water, ethanol, glucose, etc. are generally used as solvents for preparing and introducing medicinal liquids. (3) The prepared medicinal solution should be stored in a glass bottle. The light-protected medicinal solution should be placed in a brown bottle and the bottle cap should be tightly closed. The imported medicinal solution should generally be stored for no more than 1 week. (4) Follow the precautions for direct current therapy.
DC iontophoresis electrotherapy
low frequency electrotherapy
Definition: In medicine, pulse current with a frequency below 1000Hz is called low-frequency electrotherapy or low-frequency pulse current.
Characteristics of low-frequency current: (1) low voltage, small current, the electrolysis effect is weaker than that of direct current, some currents have no obvious electrolysis effect, (2) the current intensity or voltage can increase or decrease, or rise and fall, (3) it has no effect on sensory nerves It has a strong stimulating effect on motor nerves and (4) has no obvious thermal effect.
Therapeutic effects: (1) Excite neuromuscular tissue (2) Analgesia (3) Improve local blood circulation (4) Other therapeutic effects.
induced current method
Therapeutic effects: (1) Prevent and treat muscle atrophy (2) Train muscles to do new movements (3) Prevent and treat adhesions and promote blood and lymph circulation in limbs (4) Sedate and relieve pain (5) Used for electrical stimulation therapy
Indications: disuse muscle atrophy, low muscle tone, soft tissue adhesions
Contraindications: People with bleeding tendencies, skin damage, and allergic reactions
Transcutaneous electrical stimulation therapy TENS
The frequency is generally adjustable from 1 to 150Hz. The most commonly used is 70~110Hz (conventional TENS)
Therapeutic effects: (1) Analgesic (2) Improve peripheral blood circulation (3) Promote fracture and wound healing (4) Treat angina pectoris
Indications: Various acute and chronic pains: various neuralgias, headaches, joint pains, postoperative wound pain
Contraindications: It is contraindicated for those with pacemakers, the abdomen, lumbosacral area, and eyes of pregnant women.
TENS parameters Mode Intensity Pulse Frequency Pulse Width Indications Conventional TENS Comfortable numbing sensation 75~100Hz <0.2ms Acute and chronic pain; short-term pain relief Acupuncture-like TENS Suprathreshold movement, generally 1~4Hz 0.2~0.3ms Acute and chronic pain; peripheral circulation 2 to 4 times the sensory threshold; ring disorder; long-term pain relief Short-term strong stimulation, muscle rigidity or spasm-like 150Hz >0.3ms, used for minor surgeries and painful sexual exercises. Enhance analgesia during TENS contraction
Functional electrical stimulation FES
Definition: The use of low-frequency pulse current to stimulate muscles that have lost nerve control and cause them to contract to replace or correct the lost functions of organs and limbs.
Commonly used frequencies are mostly between 15~50Hz.
Medium frequency current method
Definition: The method of applying pulse current with a frequency of 1~100kHz to treat diseases is called medium frequency electrotherapy MFE.
Therapeutic effects: (1) Promote local blood circulation (2) Analgesic effect (3) Anti-inflammatory effect (4) Softening scars and loosening adhesions (5) Effect on skeletal muscles (6) Permeability effect on biofilms
Equal amplitude medium frequency current method
Indications: joint strain, neuralgia, intestinal adhesions
Contraindications: Acute infectious diseases, tumors, hemorrhagic diseases, severe heart failure, renal insufficiency, cardiac area, lumbosacral region of pregnant women, and those with pacemakers.
Interference current method ICT
Therapeutic effects: (1) Promote blood circulation (2) Analgesia (3) Reduce swelling (4) Treat and prevent muscle atrophy (5) Adjust visceral function (6) Regulate autonomic nerves (7) Promote fracture healing
Current intensity: generally within 50mA
Indications: Lumbar disc herniation, Raynaud's disease, gastroptosis
Contraindications: Acute inflammation, bleeding tendency, pregnant women's lower abdomen, local metal foreign bodies, severe heart disease, etc.
Modulated medium frequency electrotherapy MMFCT
Therapeutic effects: (1) Analgesia (2) Promote blood circulation (3) Promote lymphatic return (4) Excite neuromuscular (5) Improve smooth muscle tone (6) Regulate autonomic nervous function (7) Anti-inflammatory (8) Drug iontophoresis
Indications: Neck, shoulder, back, waist and leg pain, muscle sprains, tenosynovitis
Contraindications: People with local malignant tumors, active pulmonary tuberculosis, and cardiac pacemakers
high frequency electrotherapy
Definition: The method of applying high-frequency current with a frequency of 100kHz~300GKz and a wavelength of 3000m~1mm to treat diseases is called high-frequency electrotherapy
Short wave and ultra short wave therapy
Short wave wavelength is 100~10m, frequency is 3~30MHz, ultra-short wave wavelength is 10~1m, frequency is 30~300NHz.
Therapeutic effects: (1) Anti-inflammation and swelling (2) Sedation, antispasmodic, and analgesic (3) Improve visceral function (4) Promote tissue repair (5) Inhibit the growth of malignant tumors
The therapeutic dose and duration of short wave treatment: The therapeutic dose of short wave is divided into four levels according to the patient's feeling of warmth: no heat (level I dose): the patient has no feeling of warmth, the neon tube is bright or dark, and the current intensity is 100-120mA. Suitable for patients with early stage of acute inflammation, edema, and circulatory disorders. The treatment time is 5 to 10 minutes, 1 to 2 times a day, and 5 to 10 times is a course of treatment. Microcaloric (level II dose): The patient has a weak feeling of warmth, the neon light tube is slightly bright, and the current intensity is 130~170mA. It is suitable for subacute and chronic inflammation. The treatment time is 10 to 20 minutes, once a day, and 10 to 20 times is a course of treatment. Warming heat (level III dose): The patient has an obvious feeling of warmth, the neon light tube is bright, and the current intensity is 180~240mA. It is suitable for chronic inflammation and diseases with local circulation disorders. For example, when treating acute renal failure, warm heat is used for 30 to 60 minutes, 1 to 2 times a day, and 5 to 8 times is a course of treatment. Heat (level IV dose): The patient has a strong sense of heat, the neon tube is bright, and the current intensity is more than 240mA. Suitable for the treatment of malignant tumors
Indications: Short wave is mainly suitable for the subacute and chronic stages of injuries and illnesses. Ultrashort wave is mainly suitable for the acute and subacute stages of injuries and illnesses, and can also be used for the chronic stages.
Contraindications: malignant tumors, bleeding tendencies, tuberculosis, pregnancy, severe cardiopulmonary insufficiency, local metallic foreign bodies, and implanted cardiac pacemakers.
microwave therapy
Electromagnetic waves with a wavelength of 1m~1mm and a frequency of 300~300000MHz are microwaves.
