Final answer:
The IFC beat frequency for treating acute pain is within the range of 80-150 pps.
Step-by-step explanation:
The IFC beat frequency (pulse rate) commonly used to treat acute pain is c. 80-150 pps (pulses per second). Interferential Current (IFC) therapy is a type of electrical stimulation that is used for pain relief and promoting soft tissue healing. The frequency range of 80-150 pps is used to provide a therapeutic effect that can help manage pain, reduce swelling, and promote muscle relaxation.
