In this procedure, you are given anesthesia so that you do not feel pain. The doctor then aggressively bends your knee in an attempt to break down the scar tissue. In most cases, this procedure is successful in improving range of motion. Sometimes, however, the knee remains stiff.
Resistance heating is a product of all circuits where electric current encounters resistance; although it has many beneficial uses, it can damage or destroy electrical equipment if not controlled. Anyone who has used a kettle, toaster, or a bar heater on a chilly evening has made the acquaintance of resistance heating.
Brief Intro to RF and Microwave Heating. When energy from electromagnetic fields is transformed into thermal energy, RF heating occurs. There are two different types of RF heating methods: induction and dielectric. Induction heating takes place in materials with a high electrical conductivity, such as copper or other metals, for instance. Eddy currents are induced by the alternating electromagnetic field and the resistive losses heat up the material.
