“…For PNP, probable means that (1) the patient's symptoms fit a nerve-related distribution, (2) the history of symptoms is consistent with a nerve-related problem, and either (3a) a clinical neurological examination shows positive or negative sensory signs that match the innervation territory of the suspected nerve problem, or (3b) diagnostic tests, such as imaging or electrophysiological studies, confirm an injury or disease that explains the distribution of PNP. dian (ULNT MEDIAN ), 13,18,21,56,57,61,66,67,119,124,127 radial (ULNT RADIAL ), 122 and ulnar (ULN-T ULNAR ) 2,3,13,21,47,66,72,83,98,123 nerve tests increase strain in the corresponding nerve. Each test preferentially loads its corresponding nerve at the elbow and wrist, 13,56 suggesting that mechanosensitivity of a particular nerve near these joints may be most readily assessed by the corresponding ULNT.…”
