The impact of obesity and age on the risk of falls in elderly women

Purpose: The aim of this study was to examine the effect of obesity and age on body balance disorders in women over 60, especially whether obesity increases the FR in older females and whether age and obesity affect the same stabilographic parameters when it comes to the FR. Methods: The study consisted of 56 inactive females aged 71.77 ± 7.43 (SD). They were divided into groups according to age and obesity. Results: Obesity separately affects FRI12-6, static indicators with eyes closed (OSI EC, APSI EC, MLSI EC), and age affects FRI12-6 and static indices with eyes open (OSI EO, APSI EO). After considering design factors (age and obesity), there were statistically significant differences in OSI EO (p = 0.027), APSI EO (p = 0.034), FRI12-6 (p = 0.0002) between obese and non-obese participants in the age groups. There were no statistical differences between non-obese old and obese-young participants (p = 0.863). The interaction between obesity and age in the FR in static indices and in FRI12-6 (p = 0.73047) was not significant. Conclusions: Age and obesity affect the stabilographic parameters individually, but there is no interaction effect between them. The presence of only one of the above risk factors may increase the FR. Obesity affects stability, while age depends on other factors. If older people are not obese or fit, involutional changes could be reversed. The type of obesity and the location of the fat tissue should be taken into account in FR assessment.

The Impact

Background. There is evidence of physical exercise effect on the adolescents’ balance and strength; however it is not known how aforementioned variables respond to physical exercise with different loads and intensities. Therefore, the aim of the study was to assess the impact of single bout of physical exercise of different intensity on adolescents’ body balance and muscular strength.Methods. Thirty healthy, physically active 11–13-year-old adolescents were randomly allocated to one of the two groups. Both groups performed single bout of physical exercise of high- or low-intensity climbing up and down-stairs. Postural sway and maximum voluntary contractions (MVC) were assessed before and after physical exercise. Results. No statistically significant impact of low or high intensity exercise was found at adolescents’ MVC. High intensity exercise influenced bigger postural sway with eyes closed compared to eyes open ( p < .05). After high-intensity exercise there was a significantly greater postural sway with eyes closed than with eyes open (p < .05). Conclusions. High and low intensity physical exercise had no impact on the adolescents’ maximum voluntary contraction, whereas high intensity exercise deteriorated body balance with eyes closed.Keywords: adolescence, physical exercise, MVC, balance

Background and Purpose Fall accidents are a social challenge in Korea and elsewhere. Most previous studies have focused on the effects of reduced visual acuity due to myopia on falls and body balance. The objective of this study was to investigate whether uncorrected hyperopia was a major risk factor for falls and to establish whether the risk of falls was absolutely correlated with visual acuity. Methods Fifty-one young subjects with a mean age of 22.75 ± 2.13 years were enrolled in this study. To induce hyperopic and myopic refractive errors, spherical lenses of ±1.0–6.0 D (1.0 D stepwise) were used. Under each induced condition, fall risk index and sway power were assessed via Fourier transformation of postural sway using a TETRAX system. Results The fall risk index for eyes-closed was significantly greater than that of eyes-open with full correction (t = −5.876, p < 0.05). The fall risk index increased significantly from hyperopia induced with −4.0 D lenses (with visual acuity of 0.69 ± 0.32) compared to eyes-open with full correction (F = 3.213, p < 0.05). However, there was no significant change in the induced myopia conditions, despite a drastic decline in decimal visual acuity. Sway power increased significantly in the low-to-medium frequency band derived from the peripheral vestibular system when hyperopia was induced. A significant difference was detected in hyperopia induced with −6.0 D lenses compared to eyes-open with full correction (F = 4.981, p = 0.017). Conclusion An uncorrected hyperopia rather than myopia may increase the risk of falls, although eyes may show normal visual acuity due to the inherent accommodation mechanism. Our findings suggest that the corrected state of refractive errors is more important than the level of visual acuity as the criteria for appropriate visual input, which contributes to stable posture. Therefore, clinicians should consider the refractive condition, especially the characteristics of hyperopia, when analyzing body balance, and appropriate correction of uncorrected hyperopia to prevent falls.

Global Mean

Because the human brain consumes a disproportionate fraction of the resting body’s energy, positron emission tomography (PET) measurements of absolute glucose metabolism (CMRglc) can serve as disease biomarkers. Global mean normalization (GMN) of PET data reveals disease-based differences from healthy individuals as fractional changes across regions relative to a global mean. To assess the impact of GMN applied to metabolic data, we compared CMRglc with and without GMN in healthy awake volunteers with eyes closed (i.e., control) against specific physiological/clinical states, including healthy/awake with eyes open, healthy/awake but congenitally blind, healthy/sedated with anesthetics, and patients with disorders of consciousness. Without GMN, global CMRglc alterations compared to control were detected in all conditions except in congenitally blind where regional CMRglc variations were detected in the visual cortex. However, GMN introduced regional and bidirectional CMRglc changes at smaller fractions of the quantitative delocalized changes. While global information was lost with GMN, the quantitative approach (i.e., a validated method for quantitative baseline metabolic activity without GMN) not only preserved global CMRglc alterations induced by opening eyes, sedation, and varying consciousness but also detected regional CMRglc variations in the congenitally blind. These results caution the use of GMN upon PET-measured CMRglc data in health and disease.

Objective The purpose of this study was to evaluate the effect of hearing aids on body balance function in a strictly controlled auditory environment. Methods We recorded the findings of 10 experienced hearing aid users and 10 normal-hearing participants. All the participants were assessed using posturography under eight conditions in an acoustically shielded non-reverberant room: (1) eyes open with sound stimuli, with and without foam rubber, (2) eyes closed with sound stimuli, with and without foam rubber, (3) eyes open without sound stimuli, with and without foam rubber, and (4) eyes closed without sound stimuli, with and without foam rubber. Results The auditory cue improved the total path area and sway velocity in both the hearing aid users and normal-hearing participants. The analysis of variance showed that the interaction among eye condition, sound condition, and between-group factor was significant in the maximum displacement of the center-of-pressure in the mediolateral axis (F [1, 18] = 6.19, p = 0.02). The maximum displacement of the center-of-pressure in the mediolateral axis improved with the auditory cues in the normal-hearing participants in the eyes closed condition (5.4 cm and 4.7 cm, p < 0.01). In the hearing aid users, this difference was not significant (5.9 cm and 5.7 cm, p = 0.45). The maximum displacement of the center-of-pressure in the anteroposterior axis improved in both the hearing aid users and the normal-hearing participants.

Background and Objectives: Balance problems are the main cause of falls and fall-related complications in the elderly. The objective of this study was to investigate the balance in old people residing in nursing homes using clinical assessments. Methods: A total of 54 people participated in this cross-sectional study. Timed Up and Go (TUG) was used to assess balance regarding mobility impairments. The modified Clinical Test Of Sensory Interaction on Balance (CTSIB) was also used to assess balance regarding sensory problems. This test was used in 4 conditions: standing with eyes open on a firm surface, standing with eyes closed on a firm surface, standing with eyes open on a compliant foam, and standing with eyes closed on a compliant foam. Data analysis was done by SPSS V. 18 software. Results: The mean time for the completion of TUG was significantly higher than standard scores in all age groups (P<0.05). Postural sway during standing with eyes closed on the ground, eyes open and eyes closed on the foam was more than standing with eyes open on the ground (P<0.001). Postural sway in standing with eyes closed on the foam was more in comparison with standing with eyes closed on the ground and eyes open on the foam (P<0.001). Conclusion: Elderly people living in nursing homes had poorer motor skills to maintain balance. They also showed greater dependence on visual and sensory systems to maintain balance.

The Impact

AbstractDance as one of the earliest cultural assets of mankind is practised in different cultures, mostly for wellbeing or for treating psycho-physiological disorders like Parkinson, depression, autism. However, the underlying neurophysiological mechanisms are still unclear and only few studies address the effects of particular dance styles. For a first impression, we were interested in the effects of modern jazz dance (MJD) on the brain activation that would contribute to the understanding of these mechanisms. 11 female subjects rehearsed a MJD choreography for three weeks (1h per week) and passed electroencephalographic (EEG) measurements in a crossover-design thereafter. The objectives were to establish the differences between dancing physically and participating just mentally with or without music. Therefore, each subject realized the four following test conditions: dancing physically to and without music, dancing mentally to and without music. Each of the conditions were performed for 15 minutes. Before and after each condition, the EEG activities were recorded under resting conditions (2 min. eyes-open, 2 min. eyes-closed) followed by a subsequent wash-out phase of 10 minutes.The results of the study revealed no time effects for the mental dancing conditions, either to or without music. An increased electrical brain activation was followed by the physical dancing conditions with and without music for the theta, alpha-1, alpha-2, beta and gamma frequency band across the entire scalp. Especially the higher frequencies (alpha-2, beta, gamma) showed increased brain activation across all brain areas. Higher brain activities for the physical dancing conditions were identified in comparison to the mental dancing condition. No statistically significant differences could be found as to dancing to or without music. Our findings demonstrate evidence for the immediate influence of modern jazz dance and its sweeping effects on all brain areas for all measured frequency bands, when dancing physically. In comparison, dancing just mentally does not result in similar effects.

ABSTRACTObjectives To estimate the impact of a sensory-motor- cognitive task on postural balance, in Parkinson disease patients (Hoehn and Yahr 2-3) and to investigate possible relationships between posturography and functional balance clinical scales.Method Parkinson disease patients (n = 40) and healthy controls (n = 27) were evaluated with fluency tests, Berg Balance scale, Mini Best test and static posturography on the conditions eyes open, eyes closed and dual-task (simultaneous balance and fluency tasks).Results Posturographic data showed that Parkinson disease patients performed worse than controls in all evaluations. In general, balance on dual-task was significantly poorer than balance with eyes closed. Posturographic data were weakly correlated to clinical balance scales.Conclusion In clinical practice, Parkinson disease patients are commonly assessed with eyes closed, to sensitize balance. Our study showed that adding a cognitive task is even more effective. Static posturographic data should be carefully overgeneralized to infer functional balance impairments.
