Laboratory Studies
- Myofascial pain traditionally does not produce abnormalities in the results of the patient's lab work. Travell and Simons describe a study looking at lactate dehydrogenase (LDH) isoenzymes.1 A shift was noted in distribution of the isoenzymes, with higher levels of LDH1 and LDH2, while the total LDH remained within normal limits. In clinical practice, myofascial pain is diagnosed by way of a thorough physical examination in conjunction with an adequate medical history.
- Depending on the clinical presentation, it may be reasonable to check for indicators of inflammation, assess thyroid function, and perform a basic metabolic panel to rule out a concomitant medical illness.
Imaging Studies
- Imaging studies often reveal nonspecific change only and typically are not helpful in making the diagnosis of cervical myofascial pain; however, radiographs and a cervical spine magnetic resonance imaging (MRI) scan may be helpful in ruling out other pathology that may be present at the same time.
Other Tests
- Several research articles have attempted to identify changes on electromyograms/nerve conduction velocity studies that may be unique to patients with myofascial pain. The research has been somewhat contradictory, with some studies finding no real electromyographic activity and others finding nonspecific electrical activity. Studies by Simons and by Hobbard and Berkoff described low-amplitude action potentials recorded at the region of the myofascial trigger point. Spontaneous electrical activity apparently can be detected using high-sensitivity recordings at the site of the trigger point. The spontaneous electrical activity may be a type of endplate potential.
