Abstract
Objective. To analyze dynamic changes in the average F-wave latency in non-operated and operated patients with disc herniation and radicular compression syndrome.
Material and Methods. A total of 81 patients were examined including 29 with non-operated nerve root compression, 32 with remaining pain syndrome (failed back surgery syndrome) and recurrent disc herniation after surgery, and 20 control patients. All patients underwent electroneuromyographic study of the average F-wave latency using a functional test in the supine and sitting positions.
Results. There was no significant change in the average F-wave latency in non-operated patients with radicular syndrome, in the group of operated patients with failed back surgery syndrome and in the group of operated patients with recurrent disc herniation. The average F-wave latency decreased in the group of operated patients with instability of the spinal motion segment and in the group of operated patients with soft-tissue compression of the nerve root.
Conclusion. The study of the late neurographic phenomenon of Fwave can be performed not only in the classical static position of a patient, but also in functional tests. The absence of significant changes in the average F-wave latency in a dynamic study indicates organic nerve root compression, while its decrease serves as an indicator of functional compression.
