What is an advantage of using modulation during electrical stimulation?

Using modulation during electrical stimulation is advantageous because it prevents the development of stimulation tolerance. When electrical stimulation is applied to the body, the nerves can adapt to continuous stimulation over time, leading to a diminished response. Modulation refers to varying the amplitude, frequency, or duration of the electrical currents, which helps keep the nervous system responsive by providing a more dynamic stimulus. This variation prevents the nerves from becoming desensitized, allowing for more effective treatment outcomes over longer periods.

While enhancing comfort for the patient is important, modulation specifically addresses the physiological response of the nervous system to continuous stimulation. It is not designed to eliminate the need for careful electrode placement, as proper placement is crucial for achieving therapeutic effects. Moreover, modulation does not necessarily reduce the duration of treatment sessions; rather, it aims to improve the effectiveness of the therapy over time.
