Overview. Isaacs' syndrome is a rare neuromuscular disorder that is characterized by progressive muscle stiffness; continuously contracting or twitching muscles (myokymia); and diminished reflexes. Signs and symptoms generally develop between ages 15 and 60, with most people experiencing symptoms before age 40.
What is thoracic outlet syndrome? Thoracic outlet syndrome (TOS) is a condition whereby symptoms are produced (such as numbness in fingers, pain in shoulder, arm, and neck) due to compression of nerves and/or blood vessels in the upper chest. The passageway for these nerves and blood vessels to exit the chest and supply the upper extremities is referred to as the thoracic outlet.
