What is the typical pulse duration for neuromuscular electrical stimulation?

The typical pulse duration for neuromuscular electrical stimulation (NMES) is generally recognized to range from 20 to 300 microseconds (µsec). This range is optimal for effectively stimulating motor nerves without causing significant discomfort or unwanted side effects. Shorter pulse durations are often better for small, sensitive muscles, while longer durations can target larger muscle groups more effectively.

In the context of NMES application, staying within this pulse duration range allows for the elicitation of muscle contractions that can enhance strength, improve muscle recruitment, and facilitate rehabilitation.

Higher pulse durations beyond 300 µsec may still produce muscle contractions but could lead to increased discomfort and reduced tolerance for the treatment, detracting from the efficacy of the therapy. Thus, the selected range aligns with best practices and clinical guidelines for neuromuscular electrical stimulation.
