Final answer:
The commonly used IFC beat frequency range to reduce edema is 80-150 pps.
Step-by-step explanation:
The IFC beat frequency (pulse rate) range commonly used to reduce edema is c. 80-150 pps. IFC stands for Interferential Current, which is a type of electrotherapy used in physical therapy. It involves using two separate currents that intersect and create a beat frequency within the body. This beat frequency can help reduce edema by promoting circulation and reducing inflammation.
