[Arterial and venous blood flow disturbances in children with vertebral basilar insufficiency].

Two hundred and sixty-two patients aged from 1 month to 18 years with vertebral basilar insufficiency syndrome have been studied. This pathology is caused by the natal trauma of cervical spine and related structures, connective tissue dysplasias, anomalies of the spine, the cranial vertebral transition and spinal vessels. Basic clinical, X-ray and dopplerographic indices of vertebral basilar insufficiency (VBI) in children of different age groups have been specified.

[Evoked potentials in patients with myofascial pain syndrome in the late residual period of natal cervical trauma].

Evoked potentials (EP), including short-latency brainstem auditory and somatosensory EP, have been studied in 80 patients with myofascial pain syndrome. Brainstem dysfunction, predominantly on the ponto-mesencephalic level, and conduction delay in the somatosensory pathway on the supraspinal level have been found in patients with natal trauma of cervical spine, being most significant in patients with severe myofascial pain syndrome. EP findings showed impairments of afferent structures of nervous system and inefficiency of antinociceptive system of supraspinal level in this group of patients that could cause the development of persistent brain syndrome.

The polysynaptic spine-stem reflex in clinical neurology.

Data from 25 years of studies of the spinobulbospinal (SBS) reflex in normal conditions and in a variety of nervous system diseases with lesions of the afferent and efferent systems, subcortical brain formations, and musculature (contracture of the expressive muscles, myofascial pain syndrome) are presented. The instability of many characteristics of the reflex (latency, amplitude, duration of response, presence) is shown to characterize this reflex in normal conditions. These measures become more stable in central nervous system pathology, which is evidence for impairment of programs which construct and execute movements.

[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.

[Brain somatosensory evoked potentials in myofascial pain syndromes].

Brain somatosensory evoked potentials were studied in 113 patients with chronic myofascial pains. Comparing to milder pain, pronounced pain syndrome revealed more significant functional changes (generators for pathologically enhanced excitability), on higher levels of nervous system. At the same time, in milder pain, a large quantity of low activity generators were detected that may indicate subnormal antinociceptive system activity.
