Shock Wave Principle Shock wave is a wave with rapid increase of pressure within a very short time and then having a gradual decrease of pressure with a small negative pressure phase. It is aimed at the source of chronic pain, promoting the dissolution of calcium deposits and leading to better vascularization so as to speed up the healing process. Shockwaves work in the following ways: 1. Cells: Enhance the permeability of cell membrane by improving ion channel activity, promoting cell division, and stimulating the production of cytokines. 2. Tendons and muscle vessels: Improve blood circulation, increase growth factor B1, and enhance osteoblast mitosis. 3. NOx system: Accelerate bone remodeling and healing. 4. Improve micro-circulation and metabolism 5. Promote the dissolution of calcified fiber cells. 6. Promote the synthesis of collagen. 7. Reduce tissue tension. 8. It has analgesic effect. 9. Male erectile dysfunction (ED) treatment Indications 1. Bone tissue diseases: delayed fracture healing and bone nonunion, early adult femur head necrosis; 2. Chronic soft tissue injury diseases: long head tendonitis of biceps brachii, calcified supraspinatus tendonitis, external humeral epicondylitis, internal humeral epicondylitis, plantar fasciitis, stop Achilles tendonitis, etc. 3. Relative indications: osteoarthritis, talus osteochondral injury, tenosynovitis, acromial sliding bursitis, anterior patellar bursitis, patellar tendinitis, greater trochanteric bursitis, elastic hip and muscle spasticity, osteonecrotic disease, etc. Item Type: Erectile Dysfunction Machine Material: Metal Rated Voltage: 100-240V Rated Frequency: 47Hz-63Hz Energy Gear: 12 Frequency Gears: 16 Host Size: Approx. 15 x 8 x 4cm / 5.9 x 3.1 x 1.6in Magnetic Waves Handle Size: Approx. 24 x 5 x 5cm / 9.4 x 2 x 2in Storage Box Size: Approx. 26 x 18 x 11cm / 10.2 x 7.1 x 4.3in
