Impact of Gender, Change of Base of Support, and Visual Deprivation on Postural Balance Control in Young, Healthy Subjects

Background: Vision, vestibular sense, proprioception and muscle strength are required to maintain balance. However, gender could also play a crucial role in postural sway. Objectives: This study was used examine (i) the impact of gender, surface type, vision on sway; (ii) effects limb symmetry (iii) understand stance, type alterations dynamic sway alterations. Methods: cross-sectional which young, healthy men (n = 15) women 12) underwent balance control assessment using force plate (SATEL, 40 Hz). Postural stances were evaluated different conditions: Opened eyes (EO) closed (EC), foam vs. firm, dominant leg stance (DL) non-dominant (NDL), mediolateral (ML) an anteroposterior (AP). The (ML sway), (AP area calculated from centre pressure displacements. Results: ML sway, AP increased when (P < 0.000). Foam perturbs more than firm under EO EC conditions for both genders, as observed curve A functional exists between DL NDL all parameters: 0.720; P 0.292; 0.954). is stable genders 0.001). For direction Women significantly absent 0.01). Conclusions: altered observed. Furthermore, we concluded that have better men.
