What does modulation in electrical stimulation refer to?

Modulation in electrical stimulation specifically refers to the ability to change the magnitude or duration of a waveform. This process is significant because varying the parameters of the electrical stimulation can help prevent neural adaptation, which occurs when the body becomes accustomed to a constant stimulus. By altering the amplitude (magnitude) or the timing (duration) of the electrical signals, a clinician can effectively manage pain, enhance muscle contractions, or facilitate healing in a more dynamic manner. This adaptability is vital in therapeutic applications, as it can enhance the overall effectiveness of treatment by ensuring that the stimuli remain both relevant and impactful for the patient.
