For edema management or muscle pump NMES, which duty cycle is typical?

Explanation:
The main idea is to use a rhythm that pumps fluid out but gives the muscle frequent rest so it can recover and keep venous and lymphatic drainage efficient. For edema management or muscle pump NMES, you want a short on time with a longer off time. This allows each contraction to squeeze fluid out, while the off period lets blood flow back in and prevents fatigue from building up. Choosing a duty cycle of 1:3 to 1:5 on:off provides ample rest between contractions, maximizing the pumping effect during the off phase and reducing the risk of fatigue or ischemia from continuous contraction. Longer or equal on-times (like 1:1, 2:1, or 5:1) would keep the muscle contracted longer, increasing fatigue and reducing the effectiveness of the pump over time.
