• In 11 patients with diabetic proximal amyotrophy, F-wave latencies and F-wave ratio were longer and F-wave conduction and distal motor nerve conduction velocities were slower than in 11 control subjects. These findings and morphologic observations of vastus medialis motor endplates and intramuscular nerve filaments are consistent with proximal nerve dysfunction in the lower extremities in these patients.
