Which of the following is commonly administered alongside electrical stimulation in medical procedures?

The correct choice is ultrasound, which is commonly administered alongside electrical stimulation in various medical procedures. Ultrasound uses sound waves to create images of structures within the body and can facilitate the delivery of electrical stimulation to targeted tissues, enhance blood flow, and promote healing. When combined with electrical stimulation, ultrasound can improve the overall effectiveness of the treatment by allowing for better penetration and absorption of the stimulation in the affected area.

Other imaging techniques, such as magnetic resonance imaging, computed tomography, and X-ray, are primarily used for diagnostic purposes rather than therapeutic applications. These modalities provide structural images and do not have the direct therapeutic impact when used concurrently with electrical stimulation.
