What is the purpose of using a ramp function in electrical stimulation?

Using a ramp function in electrical stimulation involves gradually increasing the intensity of the stimulation over a defined period. This approach allows the body to acclimate to the stimulation, facilitating a more comfortable experience for the patient. A gradual increase helps to minimize discomfort, prevents sudden muscle contractions, and reduces the risk of injury due to abrupt changes in intensity.

This technique is particularly important in therapeutic settings, where the goal is to stimulate muscle activity or nerve functions without causing pain or stress. A ramp function also enables the practitioner to better control the stimulation parameters, optimizing the treatment for each individual's tolerance and response.
