Comparison of Ultrasound-guided Electrolysis Therapy vs. Sham Electrolysis in Patients With Patellar Tendinopathy: A Prospective Randomized Study Including MRI and Shear-wave Ultrasound Elastography Imaging

"Ultrasound-guided galvanic electrolysis (USGET) is a technique most commonly used on chronically affected tissue. A galvanic current flows through an acupuncture needle producing an inflammatory reaction in the tissue. The inflammatory reaction will trigger a host of biological processes in the body. These will ultimately start the generation of new immature collagen fibres. The fibres become mature by means of training stimulus.~The technique shows good results on tendons in the chronic phase, and may be used for injuries, such as long-standing muscle injury and treatment of myofascial pain syndrome and trigger points."

The same intervention as the electrolysis group with the device turned on but the current intensity turned to 0 mA (e.g., no galvanic current).
