What does modulation refer to in electrical stimulation?

Modulation in the context of electrical stimulation refers to the practice of altering pulse characteristics such as frequency, intensity, or duration during stimulation. This adjustment is critical as it helps to enhance the responsiveness of nerves and can prevent adaptation or desensitization of the target tissue. By changing these characteristics, the body is less likely to become accustomed to a constant stimulation pattern, allowing for more effective therapeutic outcomes.

This approach is particularly beneficial in applications such as pain management or muscle stimulation, where varying the stimulation can engage different nerve fibers and promote better overall response. As a result, modulation is more effective in improving the efficacy of the treatment rather than committing to a static stimulation method that may lead to diminished effects over time.
