Thoracic Outlet Neurologic Syndrome, also known as TOS, is a medical condition characterized by the compression of the nerves and blood vessels in the thoracic outlet, located between the base of the neck and the armpit. This compression can occur due to various factors, such as anatomic abnormalities, trauma, muscle imbalances, or repetitive overuse.
The thoracic outlet is a narrow space through which important nerves and blood vessels pass, including the brachial plexus and subclavian artery and vein. When these structures become compressed or irritated, it can lead to a range of neurological symptoms.
The symptoms of Thoracic Outlet Neurologic Syndrome may include pain, tingling, numbness, or weakness in the neck, shoulder, arm, or hand. Individuals may also experience a sensation of heaviness or fatigue in the affected limb. In some cases, symptoms can worsen with specific activities or positions, such as reaching overhead or carrying heavy objects.
Diagnosis of Thoracic Outlet Neurologic Syndrome involves a thorough medical history, physical examination, and occasionally imaging tests. Treatment options may include physical therapy, posture correction, stretching and strengthening exercises, pain management techniques, and in severe cases, surgery to relieve compression or remove any structural abnormalities.
It is important to note that Thoracic Outlet Neurologic Syndrome may be mistaken for other conditions, such as carpal tunnel syndrome or cervical radiculopathy. Therefore, obtaining a correct diagnosis from a healthcare professional is crucial for proper management and treatment of this condition.
