[Stimulation electromyography in evaluation of radicular disorders in lumbar osteochondrosis].

Using stimulation electromyography the state of the afferent and efferent parts of the reflectory arch was estimated at the lumbosacral level in 93 patients with lingering exacerbations of the syndromes of lumbar osteochondritis. In cases of radicular disturbances a lowering (statistically significant) of the speed of the stimulus transmission along the proximal parts of the motor fibres in the affected radicles was noted. A deterioration of the H-reflex of the musculus soleus pointed to the involvement of the first sacral radicle.
