“…Additionally, the complaint of body imbalance correctly identified 80.9% of fallers, signaling the importance of continuing this line of investigation in order to improve the early identification of the risk of falling among older adults with cognitive impairment using this question. In previous studies, the decline in body balance in older adults with cognitive impairment was identified by means of stabilometric posturography variables 12,35 , and these deficiencies in body balance were shown to be associated with an increased risk of falls in older adults with cognitive impairment and dementia 6,8,34 . However, despite these significant associations, simple balance assessment tests, such as Romberg and the Timed Get Up and Go, revealed lower estimates of accuracy for recognizing the risk of falls in older adults with cognitive impairment than those identified in the present study through the complaint of body imbalance 36 .…”

Abstract Objective: to investigate the frequency of falls and clinical and physical-functional factors associated with falls, and the accuracy of such factors to identify the risk of falling in cognitively impaired older adults. Method: a cross-sectional study with cognitively impaired older adults was carried out using the Mini-Mental State Examination. The dependent variable was a history of falls in the previous six months. The independent variables were self-reported mental confusion, hearing and visual impairment, physical fatigue, muscle weakness, dizziness, body imbalance, insecurity when walking, diagnosed depression, hospitalizations, continuous use medications (form from study used), muscle mass (calf circumference) and handgrip strength (dynamometry), functional capacity (Pfeffer) and mobility (SAM-Br). Descriptive statistics were applied. The groups were compared using the Mann Whitney U test, the risk factors were identified by univariate and multivariate logistic regression, and the area under the ROC curve (AUC) was calculated for the associated factors. Results: 216 cognitively impaired older adults were included in the analysis, 41.7% of whom were fallers. Multivariate regression analyzes indicated that complaints of visual impairment (OR=2.8; p=0.015) and body imbalance (OR=2.7; p=0.004), and greater medication use (OR=1.1; p=0.038) were associated with a history of falls. The AUC found poor accuracy for quantity of medications as a screening tool for fallers (AUC=0.6 [0.5; 0.7]; p=0.028). Conclusion: cognitively impaired older adults had a high frequency of falls. Complaints of visual impairment, body imbalance and polypharmacy were predictors of falls. The early assessment of these factors can contribute to the identification of cognitively-impaired older adults at risk of falling in clinical practice and research.

“…Our results show greater oscillations in the anteroposterior direction (p < 0.001), which is consistent with studies also carried out with older women or with elderly people of both sexes. Since the projection of our center of gravity passes in front of the third sacral vertebra, anteroposterior oscillations in search of postural stability are normal in humans [28,29]. The increase in mediolateral oscillations is associated with mild cognitive impairment [30].…”

The incidence of falls in adults constitutes a public health problem, and the alteration in balance is the most important factor. It is necessary to evaluate this through objective tools in order to quantify alterations and prevent falls. This study aims to determine the existence of alteration of balance and the influence of age in a population of healthy women. Static posturography was performed on 49 healthy adult women with no history of falls in four different situations using the Romberg test with the NedSVE/IBV® platform. The variables studied were the body sway area and the anteroposterior and mediolateral displacements. The situation of maximum instability occurred in RGC (p = 0.001), with a significant increase in anteroposterior oscillations regarding the ML (p < 0.001), with no correlation to age. Age alone does not influence the balance in the sample studied, other factors must come together to alter it. The joint cancellation of visual and somatosensory afferents could facilitate the appearance of falls, given that it is a situation of maximum instability. Proprioceptive training is interesting as a preventive strategy for falls.

“…No presente estudo, verificouse 88,9% de prevalência do déficit visual junto ao grupo de adultos (20-59 anos) e 87,5% entre os idosos. O aparelho visual, apresenta-se, por exemplo, como a primeira fonte reguladora da intensidade das oscilações corporais 39 Mediante informações visuais periféricas e centrais, o SNC orienta o posicionamento do corpo no espaço, a partir de um sistema de relação entre os eixos horizontais e verticais do corpo e objetos dispostos no entorno. Diante disso, a frequência das oscilações sobre a base de apoio é minimizada 40 .…”

OBJECTIVE: To examine the sensory performance of static and dynamic balance regulation and the risk of falling in physically active adult and elderly women.METHOD: This is a non-probabilistic and intentional cross-sectional study. Thirty four women (51.90±15.84 years) enrolled in a gym attended. The population evaluated was stratified in age groups: 20-59 years (n=18) and 60 69 years (n=16). The gait was evaluated by the Time Up and Go (TUGs), Time Up and Go manual (TUGm), and Time Up and Go cognitive (TUGc), the balance by the Dynamic Gait Index (DGI) and Body Balance Test (TEC). RESULTS: Student’s t-test showed significant differences between age groups for comorbidities: hearing, vision, vertigo, labyrinthitis (p≤0.05). Comparatively, adult women showed better performance indices than older women in physical tests. According to the standards of the tests, there was no risk of falling for any group. However, regardless of age, a detailed examination of the TEC test showed a deficit in the sensory regulation of the visual, vestibular and somatosensory systems of the static and dynamic balance of fallers and non fallers (p≤0.05). The logistic regression analysis indicated the interoceptive regulation of the dynamic balance as a predictor of fall (p≤0.05). CONCLUSION: Deficits in the vestibular and somatosensory systems gradually potentiate the risk of falls in adult and elderly women, even if they remain physically active.

Evaluation of postural balance in mild cognitive impairment through a three-dimensional electromagnetic system

Abstract: Evaluations showed decrease in balance in elderly people with mild cognitive impairment. Presence of anteroposterior displacement can be an early sign of postural control impairment, and the evaluation with visual restriction can be useful in detecting small postural instabilities.
