Midwestern University researchers discover previously unknown cause of nTOS

(Midwestern University) Neurogenic thoracic outlet syndrome (nTOS) is a common neurologic syndrome resulting in pain, numbness, and/or weakness in the arm, forearm, and hand. This condition affects 0.3-8.0 percent of the US population, and is generally caused by impingement of nerves traveling from the brachial plexus in the neck, through a region referred to as the thoracic outlet. Researchers from Midwestern University have recently discovered a previously unknown cause of nTOS and an effective method of identifying it in patients.
