It is recommended to "warm up" treatment with manipulation, passive training or physiotherapy before treatment. For example, ankle range of motion manipulation should be done before treatment of talus injury, muscle relaxation massage should be done before treatment of leg muscle spasm, and microwave therapy should be done before treatment of calcified supraspinatus tendonitis to promote microcirculation._x000D__x000D_Methods:_x000D_A. Shunting: it spreads from the starting (stopping) point to the distal end of the muscle. Advantages: it is not easy to damage the normal tissue and does not aggravate the pain;Insufficient: Long frequency, long time._x000D_B. Inverse beating: the direction is opposite to that of clockwise beating. Advantage: sometimes it can achieve amazing effect (knot principle)._x000D_C. Oblique shot: the gun is at a 45 degrees angle to the skin, especially suitable for soft tissue injury around the ankle joint_x000D_D. Parallel back and forth movement: it is a method of relieving pain during treatment and can also be applied to a wide range of lesions._x000D_E. Circular movement: it is a method of relieving pain during treatment and can also be applied to a wide range of lesions._x000D__x000D_Course of treatment: Generally 5-7 days once, 3-6 times for a course of treatment. Treatment time of extracorporeal shockwave therapy is about 5-15 minutes each time. For patients with short injury time, they can basically return to normal after one treatment. For old wounds, 5 to 7 treatments are required, with intervals of 3 to 7 days._x000D__x000D__x000D__x000D_Note:_x000D_1. Coupling agent can be applied to the affected area before treatment, and it is forbidden to pull the trigger in the state of empty gun.Do not turn on the output when the impact head is not in contact with the affected area to avoid unnecessary damage to the equipment and the patient._x000D_2. Shockwave therapy also has some side effects, including local tissue redness and swelling, subcutaneous hemorrhage, ecchymosis, pain, etc., but most of them are transient and can be alleviated or eliminated within 1?2 days after treatment._x000D_3. After treatment, drink plenty of water that day to promote circulation and expel inflammatory substances._x000D_4. At the early stage after the end of a course of treatment, try to reduce the power generated from sports or local injuries, and pay attention to rest for 1?2 weeks during treatment to make sure treatment sites_x000D_heal. The purpose of the coupling agent is first to fill the small gaps between the contact surfaces so that the air in those gaps does not affect the energy penetration.Secondly, the acoustic impedance difference between the probe and the skin channel is reduced by coupling agent "transition", thus reducing the reflection loss of ultrasonic energy at this interface.In addition, it also act as a "lubricant" to reduce the friction between the probe surface and the skin, enabling the probe to slide more flexibly. Features: 1Shockwave therapy is a simple treatment process for strain diseases, non?invasive treatment, less harm to patients, shockwave therapy equipment has more obvious analgesic effect than other physical therapy equipment, especially for periarthritis of shoulder. 2Can be used for shock therapy of tumors and cancer cells in the whole system. Periarthritis of shoulder, patellar tendinitis, heel pain, etc. 3Urinary system of extracorporeal shockwave lithotripsy treatment, erectile dysfunction treatment. 4Seven different working heads are provided and the machine will recommend different working
