For the small percentage of patients where SMA is suspected but didn’t show up in the genetic blood test, an electromyography test will be necessary. This is a fairly invasive procedure which may cause pain and discomfort to the patient.
Needle electrodes are used to record muscle activity by stimulating motor neurons which lead to electrical activity within the muscles. The test can also be used to diagnose other neuromuscular diseases such as motor neuron disease. Find out more about electromyography tests here.
