What type of electrical current is commonly used in muscle stimulation therapy?

The type of electrical current commonly used in muscle stimulation therapy is pulsed current. This method involves the delivery of electrical impulses in bursts or pulses rather than a continuous flow, which allows for effective muscle contraction. Pulsed current is particularly beneficial in therapeutic applications because it can mimic the natural firing patterns of nerve signals, facilitating muscle recovery, improving circulation, and relieving pain.

By applying a pulsed current, healthcare professionals can control the intensity and duration of the stimulation, leading to better targeted treatment of specific muscle groups or areas affected by injury or tension. This adaptability makes pulsed current especially valuable in rehabilitation and physical therapy contexts, where tailored muscle activation is necessary for effective treatment.
