Abstract

Purpose

To investigate F-wave as a method to identify a specific root lesion of L5 or S1 and to quantitatively evaluate the severity and progression of motor root lesions in lumbosacral radiculopathies (LR).

Methods

Both peroneal and tibial F-waves were performed bilaterally in 142 patients with unilateral L5 or S1 radiculopathies and 37 controls along with Medical Research Council (MRC) evaluation, and soleus H-reflexes were tested bilaterally in 78 of these 142 cases. Both F-wave and MRC were re-evaluated approximately 1 year after initial examination in 65 patients.

Results

Abnormal peroneal F-waves were found in 34 patients with L5 radiculopathy (34/67, 50.7%) along with normal tibial F-waves and soleus H-reflexes in all tested cases. By contrast, 27 patients with S1 radiculopathy presented abnormal tibial F-waves (27/76, 36.0%) along with normal peroneal F-waves in all 76 cases and abnormal soleus H-reflexes in 38 of 47 (80.9%) cases. There were significant differences in involved side F-duration among different MRC scales in both radiculopathy groups (P < 0.05). Follow-up analysis demonstrated slow progression of both F-wave abnormalities and muscle weakness in patients undergoing conservative treatment (P < 0.05).

Conclusions

Comparisons of F-waves between the same nerve on both sides and between peroneal and tibial nerves in the same leg may clearly increase the validity of F-waves for evaluating a specific motor root lesion of L5 or S1. Furthermore, a quantitative comparison of F-waves may provide additional information on the severity of individual root lesions and their progression even in the early stages of disease.
