what is an emg/ncs test
What is EMG and Nerve Conduction Study? When your muscles are sore or weak and you donât know why, there are a couple of tests that can help give you answers. One is electromyography (EMG). The other is a nerve conduction study (NCS). They are often done at the same time. Your doctor can use the results of these tests to figure out whether you have a muscular problem or a nerve problem.
