A 56 yo male presents to you with a complaint of foot drop. He is a manual labourer and has had multiple episodes of blunt trauma to his lower limbs and has also complained of lower back pain over the last few months.
How can you differentiate a peripheral nerve, versus, root cause, versus central cause?
