Abstract
AIM: To study the effectiveness of the combined use of electromyostimulation (EMS) and static exercises to correct postural balance (PB). MATERIAL AND METHODS: Seven healthy adolescents performed the static exercise 'tilt to the side' together with EMS (main group), 7 age-matched adolescents (control group), performed only the exercise. EMS was performed by the device 'Bellatronic'; current 5 A, pulse frequency 20 Hz. Stimulation was carried out for a minute, alternating 2-second exposure to electric current with a 2-second pause of rest. PB was assessed using stabilometric tests on the MBN platform. RESULTS AND CONCLUSION: The tested static exercise 'tilt to the side' together with EMC has a controlled and significant effect on the displacement of the projection of the General center of mass of the body (CMT) in the frontal and sagittal planes, provided an individual approach. No significant improvements to travel speed and area of statokinesigram in the short term are, probably, due to the unfamiliarity of the exercise and prolonged fixation of a static posture. The use of EMS on stretching muscle fibers can enhance the effect of relaxation, which can be used both independently and for the correction of the static exercises. The change in muscle tone caused by the tested static pose with the use of EMS controls and corrects in the short term the projection of CMT in the frontal and sagittal planes, an important indicator of PB.
