Document Summary
The brachial plexus is the web of nerves responsible for movement of the arm (c5 to t1) Neuropraxia is to nerves as sprain is to ankle. Lowest level of neural injury (1st level) It is a transient conduction block; lasts seconds maybe minutes with little to no structural failure. Repeated injury may result in greater neurological damage such as axonotmesis and neurotmesis (severed nerves) In canadian university football, there is 26% incidence of burners/stingers. 59% of these incidents were reported to medical staff (frequent occurrence but underreported) Linebackers and offensive line experience these the most. Shoulder hand - and/or muscular weakness in the elbow and shoulder. Unilateral; symptoms only on one side of the body (not a central nervous system issue) Full, pain-free cervical rom, no symptoms in lower extremity. Weakness/paralysis, affects abductors and lateral rotators, caused by repetitive movements (which creates build-up of tissue on posterior side of arm; rotator cuff), weakness in elbow flexors.
