“…A certain amount of learning must also take place to assist unsighted individuals in control of the upright posture and overcoming various perturbations in their environment [24]. The role of vision has been studied by Weissman and Dzendolet, who reported significant differences in the degree of postural coordination from the eyes‐open to eyes‐closed condition [25]. Another study reported that significantly less time was needed to restore balance after an aroused loss of balance under full vision [26].…”

“…Weissman,9 in a study of 12 subjects of working age, and Fernie,'° in a survey of 205 subjects over 65 years, reported no differences between the sexes. This may be because of the problems of subject numbers (9) or biases in the study populations. The elderly subjects were all institutionalized and may be a grossly abnormal sample confounding tendencies normally shown.…”

An investigation of postural sway and bodyweight distribution in standing was carried out using the Nottingham Balance Platform (NBP). The aims were to provide normative data for subsequent studies on stroke patients and to show the effect of age and sex on these variables. Male and female volunteers were recruited from hospital workers, hospital visitors and members of a local community centre. Each subject was assessed using the N BP, a limb load monitor based on load cells and a microcomputer. Weight distribution was expressed as the balance coefficient, which is the mean proportion of body weight on the left leg calculated over 30 seconds. Postural sway was calculated from the deviation from that mean and expressed as the sway coefficient. The 403 volunteers included 269 women and 134 men, age range 18-87 years (mean 50). There was a significant difference between the sexes for both postural sway (p < 0.05) and weight distribution (p < 0.01) and significant correlations between age and postural sway (p < 0.001) and age and weight distribution (p < 0.001). The results provided baseline data allowing for age and sex differences for further studies with stroke patients

“…In this study, sway was measured continuously for 10 s, whereas T1 positioning accuracy was measured intermittently over a period of -1 min. Sway has frequency components ranging from <0.02 Hz to -1 Hz (6,10,28,32). For example, Brauer and Seidel (6) show ultralow frequency sway components with a period >40 s with superimposed higher frequency components.…”

Trunk proprioception was measured in 253 healthy children 7-18 years of age using infrared markers placed on the back of the head and on the skin over the T1, T8, and S1 spinous processes. The children were tested for their accuracy in sensing return of the head and trunk to a centered, neutral position in the frontal plane. Whole-body sway was also quantified during 10 s of relaxed standing by measuring mean amplitudes of trunk marker and foot center of pressure (CP) movements. The results show that trunk positioning accuracy improved significantly with age (p = 0.000). Subjects could position their trunk in the frontal plane to within a mean (+/- SD) of 2.5 (+/- 1.1) and 0.9 (+/- 0.6) degrees of the neutral position at ages 7 and 18 years, respectively. No statistically significant gender differences were found. At every age trunk positioning accuracy was diminished in the presence of a continuous external trunk moment (equivalent to 0.01 x body weight x height), although not significantly so. Neither mean trunk sway nor CP amplitudes were significantly correlated with age or sex. The overall results suggest that spine decompensation is only abnormal when it exceeds 20 mm in healthy children and adolescents.
