Bedside exam tools? I'm a bit of a gadget freak, so when I started out I went overboard and got all sorts of stuff to do exams...including Maddox rods, a Risley
prism, a trial frame, AO-Ritter color vision book, a handheld Doppler to check pulse, a binocular indirect ophthalmoscope, a corneal aesthesiometer (which I
also used to quantify cutaneous sensation), and I even purchased a handheld laser pointer (in the mid-1980's when these weren't cheap) to perform a bedside
type of projection perimetry to better identify subtle visual field defects. This in fact allowed me once to identify at the bedside a "pie-in-the-sky" defect in a patient
who turned out to have a temporal lobe astrocytoma affecting Meyer's loop. I really felt having these "tools" would help me become a better neurodiagnostician.
I still have all of these gadgets and do use them, but over the years I've come to the conclusion that the most important exam "tool" for the neurologist is a solid
understanding of functional neuroanatomy along with the ability to recognize patient symptoms and signs, on both the history and physical exam, and to be able
to correlate these with your knowledge of functional neuroanatomy to answer the three questions that neurologists must always address: 1) Are the patient's
symptoms due to a problem with the patient's nervous system? 2) If so, where is (are) the lesion(s)? 3) What is(are) the lesion(s)?
Were I somehow able to go back 25 years to my residency training with my current knowledge, I would probably be able to do as good or better a job diagnosing
neurologic disorders at the bedside with far fewer "tools." All that you really need are the following: 1) a good reflex hammer (Babinski or Tromner); 2) a good direct ophthamoscope; 3) safety pins; 4) 128Hz tuning fork; 5) a good stethoscope; 5) a vial of some essential oil (e.g. peppermint) to test olfaction; 6) a Rosenbaum eye
chart, with a basic color blindness test on it.
