Electromyography (EMG) Explained: What It Is & What It Diagnoses Electromyography—what exactly is it, and why would your doctor order one? In this video, we break down what an EMG (Electromyography) really is, how it works, and what it can diagnose. From nerve conduction studies to the needle muscle test, this powerful diagnostic tool helps determine whether your symptoms are coming from your neck, back, peripheral nerves, or muscles. If you're dealing with numbness, tingling, weakness, shooting

How to figure out the source of knee pain? When you’re experiencing numbness, tingling, or weakness, nerve conduction studies help us identify the problem. This diagnostic test uses small electrical impulses to measure how well your nerves are transmitting signals throughout your body. By placing electrodes on your skin and monitoring nerve responses, we can pinpoint where nerve damage or compression is occurring—whether it’s carpal tunnel syndrome, pinched nerves in your spine, peripheral neuro
