The neurologist will also look for signs such as pain, loss of sensation, or extra-pyramidal rigidity, which is a different type of muscle rigidity that is frequently seen in Parkinsonâs type disorders. Step 2: Diagnostic Tests The next step in the diagnostic process often involves a series of test. These typically include an MRI (magnetic resonance imaging) of the neck, and sometimes of the head and lower spine, an EMG (electromyography) which tests nerve conduction, and a series of blood tests. Sometimes urine tests, genetic tests, or a lumbar puncture (also called a spinal tap) are also necessary.
