Balance dysfunction remains a significant factor for disability in the elderly [1]. Several mechanisms have been proposed do explain the changes in balance during aging. Balance disorders represent a growing public health problem due to the association with falls and fall related injuries [2]. The complexity of the balance system, however, often requires a thorough, multidisciplinary approach to the evaluation and successful treatment of balance impairment [3]. The vestibular system detects head movement in space and in turn generates reflexes that are crucial for daily activities, such as stabilizing the visual axis and maintaining head and body posture [4]. To measure postural balance an accurate and reliable instrument is needed that can numerically reflect the importance of the different variables involved in human balance [5]. With this study it’s our aim to directly determine the balance of older people and to establish the importance of the vestibular system in aging. University of León, León, Spain The data of postural balance in three test conditions was collated with a Metitur® force platform (normal standing with eyes open, normal standing with eyes closed, foam standing with eyes open and foam standing with eyes closed...

Objective: Physical and psychological incapacity, including fear of falling is related to decreased satisfaction with life in osteoporosis (OP). The impact of a balance exercise program on improving the quality of life is not well established. We have, therefore, investigated the effect of 12-month Balance Training Program in quality of life, functional balance and falls in elderly OP women. Methods: Sixty consecutive women with senile OP were randomized into a Balance Training Group (BT) of 30 patients and no intervention control group (CG) of 30 patients. The BT program included techniques to improve balance over a period of 12 months (1 h exercise session/week and home-based exercises). The quality of life was evaluated before and at the end of the trial using the Osteoporosis Assessment Questionnaire (OPAQ), functional balance was evaluated by Berg Balance Scale (BBS). Falls in the preceding year were noted and compared to the period of study. Results: The comparison of OPAQ variations (INITIAL-FINAL) revealed a significant improvement in quality of life in all parameters for BT compared to CG: well-being (1.61 +/- 1.44 vs. -1.46 +/- 1.32, p < 0001), physical function (1.30 +/- 1.33 vs. -0.36 +/- 0.82, p < 0.001), psychological status (1.58 +/- 1.36 vs. -1.02 +/- 0.83...

INTRODUÇÃO: Atletas de futebol podem ter melhor equilíbrio que sedentários, pois os programas de treinamento sensório-motor melhoram a função motora, aumentam o controle neuromuscular e promovem a melhora da propriocepção. Este estudo teve como objetivos: avaliar o equilíbrio postural e a influência da dominância e dos fatores antropométricos em atletas de futebol de campo e indivíduos sedentários. MÉTODOS: Foram avaliados 100 indivíduos do gênero masculino divididos em dois grupos: 50 atletas de futebol de campo (GA) com idade de 18,0+0,7 anos e 50 indivíduos sedentários (GS) com idade de 17,6+0,6 anos. Os grupos foram analisados em relação à massa corporal, estatura, índice de massa corporal (IMC), flexibilidade e percentagem de gordura. Para avaliação do equilíbrio foi utilizado o protocolo Dynamic Balance System, nível 8 de estabilidade do equipamento Biodex Balance System (BBS). RESULTADOS: Os atletas apresentaram melhores índices no membro dominante no teste para a direita (p = 0,039) e no membro não-dominante no teste para trás/esquerda (p=0,007). Os sedentários tiveram melhores índices no teste realizado para a direita (p=0,034) no membro não dominante. Nos demais índices, não houve diferença estatística. O GS teve melhor desempenho do membro não dominante quando comparado com o dominante na maioria dos testes realizados. No GA houve melhor desempenho do membro não dominante no índice de estabilidade geral (p=0...

As alterações do equilíbrio postural representam um dos principais sintomas relatados pelos pacientes com Esclerose Múltipla (EM), surgem logo no início da doença em pacientes minimamente comprometidos e são consideravelmente incapacitantes . Esses déficits são muitas vezes pouco valorizados pelas avaliações clínicas neurológicas convencionais. Os objetivos desse estudo foram descrever as alterações de equilíbrio em pacientes com diagnóstico de EM e diferenciar as alterações clínicas entre pacientes com e sem queixa de desequilíbrio. Foram avaliados 98 pacientes, classificados através da Escala Expandida do Estado de Incapacidade (EDSS) entre 0 e 4,5. Os pacientes foram divididos em 2 grupos de acordo com a presença da queixa de desequilíbrio (Grupo sem queixa - GS; Grupo com queixa - GQ). O protocolo de avaliação constou de escalas observacionais do equilíbrio (Escala de equilíbrio de BERG: EEB e Índice de marcha dinâmica: DGI), avaliação da percepção de vertical visual subjetiva (VVS), Escala de Severidade da Fadiga (FSS) e através do Inventário Beck de Depressão (BDI). Os grupos GS e GQ foram compostos por 49 pacientes cada um. Não houve diferença estatística na idade dos indivíduos entre os grupos...

Background: Falls have a high incidence in old age people and it results in severe consequences representing a public health problem. Falls are the second worldwide cause of accidental deaths (1). The literature shows that people with high depression and anxiety symptoms have impaired balance and this is more problematic in old age people (12). Some studies have shown a relationship between depression/anxiety symptoms and balance (18) however little is known how just anxiety symptoms affect balance. It is also unknown which systems responsible for balance are more affected/preserved in this population in the absence or presence of different levels of anxiety and depression symptoms. Aim: The aims of this study were to explore: the balance differences between old age people with presence/absence of anxiety and depression symptoms and how balance may be affected/preserved by the different levels of anxiety and depression symptoms in the same population. Methods: A quantitative cross-sectional study was conducted. The protocol included socio-demographic, anthropometric and general clinical data. Balance confidence was evaluated with the Activities-specific Balance Confidence (ABC), the balance with the Balance Evaluation System Test (BESTest) and with the Berg Balance Scale (BBS). The level of significance considered was set at p<0.05. Results: 136 old age people with a mean age of 75.9±8.8 years old...

Background: Falls have a high incidence in older people, representing a public health problem. They are most common in women although more mortal for men. It is known that body composition changes with aging and can predict functional and mobility problems. However, it is unknown whether the changes in the systems responsible for balance in humans are associated with age, gender or body composition. This information can contribute to understand the causes of falls and to develop prevention programs. Aim: Explore the balance-differences according to age, gender or body composition in people with 60 years or more. Methods: A quantitative cross-sectional study was conducted. The protocol included socio-demographic, anthropometric and general clinical data. Balance confidence was evaluated with the Activities-specific Balance Confidence (ABC), the balance with the Balance Evaluation System Test (BESTest) and with the Berg Balance Scale (BBS). The statistical analysis was conducted in the Statistical Package for Social Sciences (SPSS) version 22.0 for Windows. The level of significance considered was set at p<0.05. Results: 136 older people (age: 75.9±8.8) participated in this study. Balance was significantly worse with the increase of age (60-69: 86.7±15.2...

Introduction Hemiparesis is a common post-stroke impairment often associated with balance deficits. Standardized instruments for balance assessment may be useful in identifying individuals at risk of falling and evaluating intervention outcomes. Objectives To identify instruments with adequate psychometric properties and clinical application to assess balance in hemiparetic cases within the scope of physiotherapy and to verify tools most frequently used in studies that evaluated the effects of therapeutic interventions in order to improve the balance of hemiparetic patients. Methods A search was conducted in the Medline, Lilacs, PEDro, and Web of Science databases by two independent researchers, who selected and analyzed studies that evaluated the reliability and validity of balance assessment instruments and intervention results. Results and discussion The Berg Balance Scale was the most frequently used instrument in the intervention studies. Nine single-task tests (timed up and go, functional reach test, step test, four-square step test, side step test, supported standing balance, standing arm raise, static tandem standing, and weight shifting) and six multiple-task tests (Berg balance scale, Brunel balance assessment, Fugl-Meyer Assessment/balance section...

Studies of balance and risk factors for falling typically focus on the elderly population or on individuals with musculoskeletal pain. Although fibromyalgia is associated with intrinsic factors that predispose to falls (pain, depression, fatigue), few studies have researched balance and falls in this syndrome. The aim of this study was to verify the association between balance, balance self-efficacy and pain in women with and without fibromyalgia, and verify the association between Berg Balance Scale and Activities-specific Balance Confidence Scale (ABC Scale). The sample consisted of 48 women aged between 40 and 59 years, divided into two groups: Fibromyalgia group (n=22) and Control group (n=26) with asymptomatic people. Balance was assessed by Berg Balance Scale, balance self-efficacy by the ABC Scale and pain by the visual analog scale. Mean scores for pain, Berg and ABC Scale were 5.4 cm (SD 2.6), 55 (interquartile range 54-56), and 54.6 (SD 26.6) respectively for Fibromyalgia group, and 0 cm, 56 (interquartile range 55-56), and 89.4 (SD 14.4) respectively for Control group. Statistically significant differences were found in balance on comparing both groups (p=0.000 for Berg Balance Scale and 0.009 for ABC Scale) with lower values for Fibromyalgia group. In Fibromyalgia group...

Background: We have recently demonstrated the efficacy of balance training in addition to Pulmonary Rehabilitation (PR) at improving measures of balance associated with an increased risk of falls in individuals with Chronic Obstructive Pulmonary Disease (COPD). Few knowledge translation (KT) projects have been conducted in rehabilitation settings. The goal of this study was to translate lessons learnt from efficacy studies of balance training into a sustainable clinical service. Methods: Health care professionals (HCPs) responsible for delivering PR were given an hour of instruction on the principles and practical application of balance training and the researchers offered advice regarding; prescription, progression and practical demonstrations during the first week. Balance training was incorporated three times a week into conventional PR programs. Following the program, HCPs participated in a focus group exploring their experiences of delivering balance training alongside PR. Service users completed satisfaction surveys as well as standardized measures of balance control. At six month follow-up, the sustainability of balance training was explored. Results: HCPs considered the training to be effective at improving balance and the support provided by the researchers was viewed as helpful. HCPs identified a number of strategies to facilitate balance training within PR...

EINLEITUNG: Das Posturomed ist ein Gerät mit instabiler Balance-Plattform, das zum Training sensomotorischer Fähigkeiten entwickelt wurde und durch Kombination mit einem Wegaufnahmesystem zur Quantifizierung des Balancevermögens eingesetzt wird. In der vorliegenden Arbeit wurden das Balanceverhalten und die Reaktion auf Störungen des Standes von Gesunden untersucht, Unterschiede zwischen jungen und älteren Probanden herausgearbeitet und mit dem Balanceverhalten von Hüft- und Kniepatienten verglichen. METHODE: 111 Probanden wurden im Einbeinstand auf dem Posturomed getestet: 59 gesunde Probanden (38±16 Jahre, Einteilung in drei Altersklassen), 26 Hüftarthrose- und Hüftprothesepatienten (59±9 Jahre) und 26 Kniearthrose- und Knieprothesepatienten (63±8 Jahre). Gemessen wurden "Einbeinstand ohne Störung" und "Reaktion auf frontale und laterale Störung des Standes". Ausgewertet wurden der Gesamtweg der Platte, der Weg in zwei zueinander senkrechten Bewegungsrichtungen und der Anteil ungültiger Messungen. ERGEBNISSE: Für die Posturomed-Messungen wurde gute Reproduzierbarkeit mit geringen Verbesserungen bei der Re-Test-Messung nachgewiesen. Im Mittel benötigen Gesunde 51,5 mm um den Einbeinstand über sechs Sekunden erfolgreich zu bewältigen. Das Wegsignal nimmt mit steigender sportlicher Aktivität kontinuierlich ab. Junge Probanden stehen ruhiger auf dem Posturomed und machen nur halb so viele Fehlversuche wie ältere Probanden. Kniepatienten benötigen deutlich mehr Ausgleichsbewegungen und weisen einen hohen Anteil ungültiger Messungen auf. Hüftpatienten stehen ruhiger und machen sogar weniger Fehlversuche als die altersentsprechende Normalgruppe. DISKUSSION: Störungen sind für Ältere schwerer zu bewältigen...

Im Karate sind vielfältige konditionelle und koordinative Fähigkeiten gefragt. Insbesondere an die Kraftfähigkeit bestimmter, stark belasteter Muskelgruppen wie den Knieflexoren und -extensoren sowie an die Gleichgewichtsfähigkeit werden hohe Anforderungen gestellt. Die vorliegende Studie untersuchte die Auswirkungen eines allgemeinen propriozeptiven Gleichgewichtstrainings mit sportartspezifischen Elementen auf die Kraftfähigkeit der genannten Muskelgruppen im Vergleich mit einem klassischen Maximalkrafttraining. Weiterhin wurde ebenso die Wirkung der beiden Trainingsmaßnahmen auf die Gleichgewichtsfähigkeit beobachtet und verglichen. Zusätzlich wurde untersucht, inwieweit die beiden Interventionen dabei jeweils Ungleichgewichte (Differenzen) zwischen linkem und rechtem Bein verringern konnten. An der Studie nahmen 24 Karatekas teil, von denen jeweils zwölf der Gleichgewichts- bzw. der Kraftgruppe randomisiert zugeteilt wurden. Über 8 Wochen wurde in jeweils 30 Minuten dauernden Einheiten zweimal pro Woche das Gleichgewichts- bzw. das Krafttraining für die Oberschenkelmuskulatur durchgeführt. Dabei beinhaltete das Gleichgewichtstraining ein- und beidbeinige Gleichgewichtsübungen auf instabilen Flächen, bei denen Trainingsgeräte wie Schaumstoffunterlagen...

BACKGROUND: Large positive sodium balances, independent of fluid balance, may lead to expanded extracellular fluid volumes and adverse clinical outcomes in the critically ill, including impaired oxygenation. OBJECTIVES: To estimate sodium and fluid balances in critically ill patients needing invasive mechanical ventilation (MV) for more than 48 hours and to evaluate the relationship between fluid balance, sodium balance and respiratory function (PaO2/FiO2 ratio and length of MV). DESIGN AND SETTING: A prospective, observational study of 50 patients on MV in four tertiary intensive care units. MAIN OUTCOME MEASURES: Daily sodium and fluid input and output, biochemistry, haemodynamic variables, oxygenation (PaO2/FiO2) and steroid and vasopressor administration were recorded for 3 days after study enrolment. Outcome data included the duration of invasive MV, ICU and hospital mortality and ICU and hospital lengths of stay. RESULTS: Fifty patients (33 men [66%]) with a mean age of 62.8 years (standard deviation, 14.6 years) and a median admission Acute Physiology and Chronic Health Evaluation III score of 82 (interquartile range [IQR], 61-99) were studied. By Day 3 after enrolment, the median cumulative fluid balance was 2668 mL (IQR, 875-3507 mL) and the cumulative sodium balance was +717 mmol (IQR...

Malgré un intérêt grandissant pour la question du devenir des survivants de tumeur cérébrale pédiatrique, l’évaluation de leur équilibre est souvent négligée. Les objectifs de nos travaux étaient de 1) examiner les écrits portant sur l’équilibre chez les survivants de tumeur cérébrale pédiatrique; 2) comparer l'équilibre debout et la qualité de vie entre les survivants et un groupe d’enfants témoins; et 3) examiner l'association entre l'équilibre debout et qualité de vie chez les survivants. Notre recension des écrits démontra que les survivants de tumeur cérébrale présentent des troubles de l’équilibre, mais les limites méthodologiques des études nous empêchent de conclure de manière définitive. Ensuite, nous avons recruté un groupe d’enfants survivants d’une tumeur cérébrale de la fosse postérieure et un groupe d’enfants sains. Leur équilibre était évalué à l’aide du Bruininks-Oseretsky Test of Motor Proficiency-2nd edition (BOT-2) et du Pediatric Balance Scale (PBS). Certains participants ont aussi été évalués avec une plate-forme de force où les limites de stabilité étaient documentées. Finalement, tous les enfants et leurs parents remplissaient le Pediatric Quality of Life Inventory (PedsQL4.0). Nos résultats démontrent que les survivants présentent une diminution de l’équilibre mise en évidence par le BOT-2...

Compromised balance and loss of mobility are among the major consequences of Parkinson's disease (PD). The literature documents numerous effective interventions for improving balance and mobility. The purpose of this study was to verify the effectiveness of two exercise programs on balance and mobility in people with idiopathic PD. Thirty-four participants, with idiopathic PD that ranged from Stage I to Stage III on the Hoehn & Yahr (H&Y) scale, were assigned to two groups. Group 1 (n = 21; 67±9 years old) was engaged in an intensive exercise program (aerobic capacity, flexibility, strength, motor coordination and balance) for 6 months: 72 sessions, 3 times a week, 60 minutes per session; while Group 2 (n = 13; 69±8 years old) participated in an adaptive program (flexibility, strength, motor coordination and balance) for 6 months: 24 sessions, once a week, 60 minutes per session. Balance and basic functional mobility were assessed in pre- and post-tests by means of the Berg Balance Scale and the Timed Up and Go Test. Before and after the interventions, groups were similar in clinical conditions (H&Y, UPDRS, and Mini-Mental). A MANOVA 2 (programs) by 2 (moments) revealed that both groups were affected by the exercise intervention. Univariate analyses showed that participants improved their mobility and balance from pre- to post-test. There were no differences between groups in either mobility or balance results. Both the intensive and adaptive exercise programs improved balance and mobility in patients with PD. © 2009 Elsevier Ltd. All rights reserved.
