Figure 3 Before and after electrical stimulation, the brachial artery flow/diameter parameters in a patient diagnosed with irritable bowel syndrome. A: Before electrical stimulation, the brachial artery flow/diameter parameters of a 38-year-old female patient diagnosed with irritable bowel syndrome were assessed to be 53.2 mL/min, 3.2 mm; B: The post-stimulation values of the same patient were 120 mL/min, 4.7 mm.
