neuro assessment more specific

Im in Christmas clinic this week and as fourth years are together with third year students I had the change to observe a case history process a third year was taking. On this patient I observed a neuro-assessment was required. I had learned all the interpretations and meanings before but it was good to go over this again with the tutor after we saw the patient. Joint position sense travels through the dorsal column and Pin prick tests for the spinothalamic tract. With pin prick tests it is necessary that the patient feels it as a pin rather then just tough. Light touch assessment would not be clinical relevant as it travels through both pathways and therefore does not allow to make a specific statement. This was a great change to recap my knowledge on the relevance of neuro assessment tests!
