Assessment of Static Postural Control in Teenagers with Down Syndrome

This study evaluated stance control in 24 teenagers with and without Down syndrome (DS) by (a) assessing center of foot pressure variables under different conditions of availability of visual and somatosensory inputs and (b) analyzing postural perturbation and adaptation following abrupt changes in visual information. Results showed no gender-related differences in either group. Group comparison revealed similar strategies in adolescents with and without DS, although quantitative differences may exist in the ability to integrate sensory inputs to control stance. Adaptation to changing environmental conditions varied greatly from one individual to another in the two groups. Finally, comparison of the two experiments suggests that the increased postural oscillations reported for the sample with DS on long lasting recordings could be related to insufficient allocation of cognitive resources in stable environments.

The Mean

To confirm the 1994 findings of Okuzumi, Haishi, and Kokubun, the displacement of the center of foot pressure, one-foot balance and bead sway were measured in children with Down syndrome ( n = 11) compared to those with other types of mental retardation ( n = 17). The magnitudes of the displacement of the center of foot pressure and head sway were not significantly different between the Down group and other forms of mental retardation, whereas the performance of one-foot balance was significantly lower in the Down group. The mean frequencies of sway waves were generally higher in the Down group, and the differences between the two groups were significant except for sagittal head sway. The results generally supported the prior findings. We proposed that it was not the magnitude of the displacement of the center of foot pressure but rather the manner of the whole body's sway which might be related to postural control.

Center Of Foot Pressure

To assess body equilibrium in athletes with intellectual disability, 60 adults with intellectual disability (30 Down syndrome, 30 nonsyndromic) participating in the 2005 Italian Special Olympics games were tested, and data for 30 healthy control adults were tested. Each subject performed four posturographic tests with open eyes, open eyes and cotton rolls between antagonist teeth, and closed eyes and cotton rolls between teeth. For each subject and test, oscillations of the body's center of foot pressure on a force platform were measured. Comparisons of the center of foot pressure sway area between groups were computed. Ratios of the sway area for the center of foot pressure among experimental conditions were compared for all athletes. The athletes with Down syndrome had larger sway of center of foot pressure area than controls and smaller than that of athletes for the nonsyndromic. All participants oscillated less with open eyes than with closed eyes. The cotton rolls reduced the sway area for the center of foot pressure by participants, while athletes with intellectual disability showed larger body sway than healthy ones, but cotton rolls between the teeth seemed to improve their postural performance.

Abstract Background: The post-mastectomy changes to the locomotor system are related to the scar and adhesion or to the lymphatic edema after amputation which, in turn, lead to local and global distraction of the work of the muscles. These changes lead to body statics disturbance that changes the projection of the center of gravity and worsens motor response due to changing of the muscle sensitivity. Objective: The aim of the study was to evaluate the static balance of women after undergoing mastectomy. Methods: The study included 150 women, including 75 who underwent mastectomy (mean age: 60±7.6) years, mean body mass index (BMI): 26 (±3.6) kg/m2) and 75 who were placed in the control group with matched age and BMI. The study was conducted using a tensometric platform. Results: Statistically significant differences were found for almost all parameters between the post-mastectomy group and group of healthy women, regarding center of foot pressure (COP) path length in the Y and X axes and the mean amplitude of COP. Conclusions: First, the findings revealed that balance in post-mastectomy women is significantly better than in the control group. Second, physiotherapeutic treatment of post-mastectomy women may have improved their posture stability compared with their peers.
