THE ISCHEMIC NEUROPATHY OF THE LOWER LIMBS – INVOLVEMENT OF THE MOTOR FIBRES
Abstract:
Secondary affection of the peripheral nerves of lower limbs during the chronic obliterative
arteriopathy stands for ischemic neuropathy. The aim of this article is to establish the involvement degree of
the peripheral nervous system and the muscle fiber in the ischemic pathology, by comparing the functional /
clinical aspects and also to set an electroneurographic and electromyographic investigation grid for patients
with ischemic pathology. The study results showed that the decrease of the motor potential amplitude is much
more common in comparison with the decease of conduction velocity, suggesting a predominantly axonal
impairment of the motor nerves. Both the motor potential amplitude as well as the motor velocity decrease
differently on the studied nerves, fact that suggests the presence of multiplex mononeuropathy. A significant
proportion of the studied nerves are normal, sustaining the predominantly inhomogeneous effect on the
peripheral nerves in ischemic neuropathy. The most commonly encountered electromyographic aspect is the
chronic neuropathic type, more rarely with the presence of active denervation signs.
