In NMES, a duty cycle of 1:3 corresponds to which on/off pattern?

• A. 3 seconds on, 9 seconds off
• B. 18 seconds on, 6 seconds off
• C. 6 seconds on, 18 seconds off
• D. 60 seconds on, 60 seconds off

Answer: (C)

A 1:3 duty cycle means the off time is three times as long as the on time. In NMES, you pick an on duration and then set the off duration to be three times that amount. If the device is set to six seconds on, the off time should be eighteen seconds to maintain the 1:3 ratio. That gives a 24-second cycle (6 on, 18 off), which is a common way to structure the pattern while keeping fatigue in check. Notes: a shorter on-time with a 1:3 off-time, like 3 seconds on and 9 seconds off, would also reflect the same ratio, but the example shown uses 6 and 18 seconds, illustrating the same principle with a longer cycle.
