3.2.2. 1 Electro-acupuncture
Electro-acupuncture is a kind of therapy by which the needle is attached to a trace pulse current after it is in-serted to the selected acupoint for the purpose of produ-cing synthetic effect of electric and needling stimulation. Different kinds of electric instruments are used. Most of them are composed of semiconductor elements and adopt oscillators. They generate low-frequency impulse current which is close to bioelectric current in the human body.
3.2.2. 1.1 Manipulations
After the needle is inserted into a certain acupoint and the needling sensation is felt, adjust the output potential instrument of the electro-acupuncture stimulator to zero, then connect the two output wires with the two needle handles, select the required waveform and fre-quency, and then gradually amplify the output current to the tolerance of the patient. One to two minutes later, the human body will be adaptive to the stimulation and feel that the stimulation is getting weaker. At the time, in-crease the output current appropriately. The stimulation continues for 10 - 20 minutes or longer according to the pathological conditions of the patient. When the treatment is finished, the output potential instrument is adjusted back to zero, the electricity supply is cut off, the wires are taken away and then the needles are withdrawn.
3. 2. 2. 1.2 Scope of application
Generally speaking, it can be used to treat any dis-ease within the indication of acupuncture, especially pain syndromes, obstructive syndromes, flaccidity syndromes. It can also be used for acupuncture anaesthesia.
3.2. 2. 1.3 Cautions
Before using the electro-acupuncture stimulator, careful examination mustbe made to make sure that it is in good condition and that the switches are off.
The current should be reinforced gradually in adjust-ment. Sudden increase should be avoided lest spasm of the muscles and breaking of the needles be caused.
If the highest output voltage of the electro-acupunc-ture stimulator is over 40 volts, the strongest output cur-rent should be controlled within 1 mA to prevent electric shock.
For the patients with cardiopathy, the current return circuit through the heart should be avoided. For the pa-tients with weak physique, it is inadvisable to adopt strong current in order to avoid fainting.
It is inadvisable to select the needles that were used for heated needling, because their handle surface is oxi-dized and cannot conduct electricity.

3. 2. 2. 2 Acupoint injection
Acupoint injection, also known as "water-needling", is a therapy used to inject the medicated solution into an acupoint or a point with positive reaction to produce a syn-thetic effect of acupuncture and medicaments.
3.2, 2, 2. 1 Manipulations
The medicated solution is drawn with a suitable injec-tor and a syringe needle, inserted quickly to the subcuta-neous region of an acupoint and pushed it slowly to a cer-tain depth. When the needling sensation (such as aching and distention) is induced, the syringe needle is with-drawn a little and the medicated solution is injected if there is no blood drawn into the injector. For the patients with deficiency syndrome or poor constitution, the speed of injection should be slow; while for the patients with ex-cessive syndrome or good constitution, the injection can be quickened appropriately.
The injection dose for each acupoint depends on the location of the acupoint, pathological conditions of the pa-tient and the concentration of the medicated solution. Generally speaking, the injection dose for the acupoints located on the head and face is 0.3 - 0.5 ml, for those lo-cated on the chest and back region is 0.5 - 1 ml, and for those located on thick muscles of the limbs, waist and but-rocks is 2 - 5 ml. For injection with small dose, the dose is 1/10 - 1/2 of the original dose of medicated solution. Usually the injection can be given once a day or once every other day. Six to eight times make up one course of treatment. For the treatment of emergent syndromes, the injection is given once or twice a day.
3. 2. 2. 2. 2 Scope of application
Acupoint injection can be used to treat most of the diseases in all clinical departments and often be applied to obstructive syndrome, stomachache, chronic bronchitis, asthma, and hypertension.
3. 2. 2. 2. 3 Cautions
Strict sterilization is needed to avoid infection; atten-tion should be paid to the properties, pharmacological ac-tion, dosage, contraindication of compatibility, term of validity, side effect and allergic reactions of the drugs. As to the drugs which can induce allergic reaction, hypersen-sitive test should be done first. The vessels, articular cavity, and spinal column should in no case be injected with drugs. When the needle tip touches the trunk of the nerve and the patient feels like electricity shock, the nee-dle must be withdrawn, the angle of insertion must be changed and the drugs are injected after the trunk of nerve is avoided. This therapy should be used with great care to treat the aged, patients with poor constitution, pregnant women and infants.

3.2. 2. 3 Scalp acupuncture
Scalp acupuncture, also known as "head acupunc-ture", is a therapeutic method to puncture specific stimu-lating zone on the scalp, which is mainly used to treat encephalopathy.

Method. The index finger in semi-flexion, the palmar surface of the thumb and the ra-dial surface of the index finger hold the needle handle, twirl and rotate the handle quickly at the speed of approxi-mately 200 times per minute for 1 - 2 minutes (or use electro-acupuncture to replace twirling and rotation of the needle), retain the needle for 5 - 10 minutes, repeatedly manipulate the needles for twice or 3 times and then withdraw the needle. During the retention of the needles, the patient is advised to exercise the affected limb (or do-ing passive movement) to strengthen functional exercise. This treatment is given once a day or once every other day and 10 - 15 times make up one course of treatment. There is an interval of one week between two courses of treatment.

3.2. 2. 4. 4 Detection of Ear Acupoints
When pathological changes have taken place in the human body, usually "positive reaction point" can be de-tected at the corresponding areas of the auricle, such as tenderness, discoloration and pigmentation, morphologi-cal changes (upheaval, depression and cords), desquama-tion, pimples, low electrical resistance, and so on. These points are used not only for clinical diagnosis, but also for treating diseases. Therefore when the prescription based on the symptoms is formulated, reaction points should be detected through careful observation, pressure with the needle handle, or determination with the electrical resist-ance of the skin for strengthening the curative effect.
3.2.2.4. 5 Manipulations
The ear acupoints are sterilized routinely with 2% iodine and 75 % alcohol. The acupuncturist holds the auri-cle with the left hand and swiftly inserts the filiform nee-dle of 0.5 cun or pin-like needle with the right hand into the depth of the cartilage, avoiding penetration through the ear. The usual sensations are pain, or distension or burning. The needles are usually retained for 20 - 30 mi-nutes. But chronic diseases, the needles may be retained for a longer period, and during which the needles can be manipulated at intervals. Pin-like needles are fixed into the acupoints with adhesive tapes and can be retained for 2 - 3 days. After the needle is withdrawn, the punctured acupoint is pressed with a sterilized dry cotton ball to avoid bleeding. Such a treatment is given once a day or once every other day. Ten times make up one course of treatment. There is an interval of 5 - 7 days between two courses of treatment.
Apart from needling, auricular-plaster therapy is also a commonly used therapy in clinical treatment. Method. The skin is sterilized routinely. Small granular drugs, such as Wangbuliuxingzi (Semen Vaccariae), is fixed onto the ear acupoints with adhesive tape. The patient is ad-vised to press the acupoints several times a day and about 1 minute for each point. It is changed once every 3 ¨C 5 days. Five to ten times make up one course of treatment.
3. 2. 2.4. 6 Cautions
Sterilization must be strict to avoid infection. Nee-dling should not be used if inflammation or chilblain is present on the auricle. For slight inflammation, 2.5 % alcohol should be applied timely to it.
Ear acupuncture is inapplicable to gravida with the history of miscarriage. It is inadvisable to be used to treat the aged and patients with weak constitution and overstrain.
