ABSTRACT

AIM. To determine the effects of vibration therapy devices exposure with a constant and aperiodic frequency of vibrations on the tissue of the biceps muscle of the shoulder.

MATERIAL AND METHODS. The study was conducted on 10 volunteers aged 24-35 years. The program Adobe Audition CC 2020, the device for vibration therapy with a constant vibration frequency “Charm 1-t”, the device for vibration therapy with an aperiodic vibration frequency “Individual massager with a pseudo-boiling layer” (MI EPS), the robotic biomechanical diagnostic and training complex with biological feedback CON-TREX were used. The measurement of the maximum strength of the biceps brachii muscle was carried out once to detect sensitivity to vibration, and then during 7 days for the dynamics of power characteristics. The maximum force was measured before exposure to vibrotherapy devices and immediately after exposure using the isokinetic classical mode of operation of the diagnostic system.

RESULTS. In a single measurement of biceps strength on one shoulder in a group of women, the average increase in muscle strength after using the Charm 1-T device was 0.8 N (2.3%), after using MI EPS – 1.9 N (6.4%). In the group of men, the average increase in muscle strength after using the device “Charm 1-T” was 1.9 N (3.2%), after using “MI EPS” – 4.6 N (7.2%). At the seven-day follow-up, the average increase in strength in the group of women on the right hand after using the Charm 1-T device was 21.8% (5.6 N), on the left hand after using MI EPS, the increase was 23.2% (6.1 N). In the group of men, the average increase in strength on the right hand after using “Charm 1-T” was 53% (30.7 N), on the left hand after using “MI EPS” – 15.5% (11.5 N).

CONCLUSION. All participants in the study groups were determined to be sensitive to both types of vibration exposure. The study participants demonstrated an increase in strength indicators when testing the biceps muscle of the shoulder, and there was also an improvement in the tolerability of the procedure itself.
