Source: Badran, B. W., et al. Laboratory Administration of Transcutaneous Auricular Vagus Nerve Stimulation (taVNS): Technique, Targeting, and Considerations. J. Vis. Exp. (2019)This video demonstrates transcutaneous auricular vagus nerve stimulation (taVNS), a noninvasive method for modulating brain activity. Electrodes are placed on the anterior wall of the outer ear canal and the tragus, targeting the auricular branch of the vagus nerve (ABVN). When stimulated, the resulting nerve impulse...

Determination of glomerular filtration rate (GFR) is the gold standard to assess overall kidney function. However, traditional procedures to measure this parameter are cumbersome and require a large investment of time. Here we describe a faster and minimally invasive method to determinate GFR transcutaneously.

This protocol outlines the use of transcutaneous neuromuscular electrical stimulation for treating varicocele-induced scrotal pain. It compares visual analog scale (VAS) scores and imaging changes before and after treatment to assess effectiveness. Results indicate that patients experienced improved scrotal pain symptoms following the treatment.
FAQs
These parameters influence how strongly and how often underlying tissues respond to surface stimulation. Intensity affects the strength of the applied stimulus, while frequency changes its timing pattern and pulse duration determines how long each stimulus lasts. Researchers adjust these variables together with electrode placement to influence sensory or motor fibers and produce different physiological responses.
Electrode placement helps determine which underlying nerves, muscles, or tissues receive the strongest influence from the applied stimulus. Because transcutaneous methods act through the skin, positioning becomes an important control over whether stimulation primarily affects sensory or motor fibers. Careful placement therefore supports more consistent pain-management, rehabilitation, and physiological-response studies.
The key distinction is where the stimulus is delivered. Transcutaneous approaches apply stimulation through the skin rather than relying on implanted devices. This noninvasive arrangement makes them comparatively accessible for studying peripheral and central nervous system responses, while also supporting therapeutic development without requiring an implanted component.
A basic setup requires selecting surface electrodes, positioning them over the relevant body region, and applying a controlled electrical stimulus. The operator then defines the stimulus intensity, frequency, and pulse duration according to the intended sensory, motor, or tissue response. These choices provide a structured basis for examining physiological effects or supporting rehabilitation and pain management.
Medical applications include pain management, neuromuscular rehabilitation, and functional training. Researchers may also select transcutaneous stimulation when they need to investigate responses in the peripheral or central nervous system without using implanted devices. Its noninvasive delivery supports both therapeutic intervention development and controlled examination of how stimulation influences nerves, muscles, and related tissues.
By varying stimulus settings and electrode placement, studies can examine how sensory or motor fibers respond to controlled input. The resulting observations may help characterize peripheral and central nervous system responses and relate stimulation conditions to functional effects. In medicine, this information can guide investigations of pain, neuromuscular function, rehabilitation strategies, and therapeutic intervention design.
