[Spinal-bulbo-spinal polysynaptic reflex in clinical neurology].

The data of 25-year study on "bulbar" spinal reflex (BSR) in health and different neurological diseases with afferent and efferent system damages, subcortical brain lesions and muscle lesions (mimic muscle contracture, myofascial pain syndrome are presented). The instability of the majority of the reflex characteristics (latency, amplitude, response duration, display) was shown to be its key feature in normal conditions. In a case of central nervous system pathology, stabilization of these parameters takes place that evidence for defect in the movement programming and performance. In damaging peripheral sections of neuromotor system, any substantial BSR characteristics changes were not detected.
