Association between clinical condition and F-waves changes in the acute phase of stroke
ABSTRACT Objective To relate F-waves with clinical and laboratory exams in the acute phase of stroke. Methods Inclusion criteria for this cross-sectional study were: hemiplegia, absence of previous cranial trauma, myopathy, diabetes, alcoholism or other known causes of peripheral neuropathy, and...
