What is the typical sensation progression during NMES, and what is the minimum pulse rate stated?

• A. From mild numbness to heat, with a pulse rate of at least 5 Hz.
• B. From mild prickling to strong contraction, with a pulse rate of at least 30 mhz.
• C. From burning sensation to tingling, with a pulse rate of at least 60 Hz.
• D. From tingling to numbness, with a pulse rate of at least 20 Hz.

Answer: (B)

During NMES, the stimulus starts you off with a mild sensory sensation (often prickling or tingling), and as intensity rises you progress to a stronger, visible muscle contraction. The minimum pulse rate needed to produce a smooth, tetanic contraction is about 30 Hz (pulses per second). The option that describes this progression and a minimum of 30 Hz matches typical NMES behavior. Note that the unit should be Hz, not MHz. Other choices describe sensations that aren’t typical for NMES or use the wrong ordering or units, which doesn’t align with standard NMES responses.
