STUDY OF THE EFFECT OF MOBILE PHONE USE ON HUMAN POSTURAL STABILITY BY STABILOMETRY AND PLANTHOGRAPHY

Purpose. To investigate the effect of mobile phone use on postural resistance, taking into account the underlying asymmetry of the lower extremities. Materials and methods. The study involved 31 subjects. Postural control was evaluated using the Stabilan-01-2 stability analyzer and the Tekscan pedobarographic platform. Subjects performed tests in the main rack and while using the phone (watching dynamic video). Statistical analysis was performed using Student's and Wilcoxon's criteria (p < 0.05). Results. 3 groups were identified by support asymmetry: left-sided, right-sided, with a symmetrical type of support. The greatest stability was recorded in people with right-sided asymmetry (ellipse area 81.87 ± 13.51 sq. Mm). In persons with a symmetrical type of support, the use of the phone worsened stability. No significant changes were observed in the group with pronounced lateralization. Conclusions. A group with a symmetrical type of support is most susceptible to destabilization when using a phone. The results highlight the importance of considering individual features of the support system in balance studies.
