Needle EMG; is the examination performed with specially designed, disposable, very thin needles resembling a wire. The electrical activity in a muscle is recorded by inserting a needle electrode into that muscle, and no electrical stimulation is given during the procedure. During the examination, you are asked to perform some movements to activate the relevant muscle. Although mild pain is felt during the procedure, it is well tolerated by most patients.
With this examination, it is possible to have an idea about whether there is an error in the transmission from the motor neurons to the muscle, if there is, the temporal process of the damage, and whether the recovery has begun. Patients using blood thinners (coumadin, aspirin, etc) should inform the doctor who will perform the examination beforehand.
