[INFLUENCE OF FUNCTIONAL MUSCULAR TEST ON BLOOD FLOW VELOCITY ON MEDIAL CEREBRAL ARTERY DURING TREATMENT OF PATIENTS BY G. A. ILIZAROV].

Abstract

It was evaluated the influence of functional test on blood flow velocity (BFV) on medial cerebral arteries (MCA) at healthy persons of different age (30 persons at the age of 5-60 y. o.) and in patients (28) during operative limb lengthening for 2-15 cm. BFV was examined by the ultrasonic dopplerography method at rest, and repeated on both brain sides in handhold of gripper by right hand then left one. In healthy persons, with age increasing, reduction of BFV on MCA was observed, and was more significant in patients with orthopaedic pathology. In four-time repetition of functional test variants, maximum range of BFV variation on MCA did not grow out of 17-25 %. During the process of operative limb lengthening in significant reduction of BFV on MCA and increasing of range BFV variation, working capacity of patients was disturbed. Age-delayed BFV on MCA develop slowly with a saving of BFV changes variability, it is a prerequisite of saving of brain centers function.
