Shocks and Needles? Demystifying the EMG Study at UCSF (Video)

Hearing terms like “shocks” and “needles” can make anyone anxious about an upcoming medical test. In this video, Dr. Camille Guzel, a Physical Medicine and Rehabilitation specialist at UCSF, helps remove the fear factor from electrodiagnostic studies.

Dr. Guzel walks through exactly what happens during the two parts of the exam—the nerve conduction study and the needle electromyography (EMG)—and explains why these tests are essential for evaluating nerve health. She also describes what the sensations actually feel like (think rubber band snaps, not pain) and shares simple tips on how to prepare for your appointment.

In this video, you’ll learn about:

  • The two parts of the study: How nerve conduction studies differ from needle EMGs

  • What it feels like: An honest look at discomfort levels—often described as “surprising” or like a snapping rubber band, rather than intolerable

  • How the test works: How UCSF physicians interpret your body’s electrical signals to identify nerve pinch points

  • Preparation and aftercare: What to wear and what activities are recommended after your visit

At UCSF, our goal is to provide accurate, reproducible data to guide your care—while prioritizing your comfort every step of the way.
