“…The increase in the CoP mean velocity (as observed in the present study, Figure 2B) has been considered an important predictor of the risk of falls in the elderly [26,43]. In addition, high levels of anxiety can modulate oculomotor control [47] and influence orthostatic postural control in young adults [48] as in the elderly [49], partially explaining the results observed in the present study.…”

“…The Wii Balance Board (WBB) was used as a posturography technique to study postural behavior as an indicator of stability [25], as well as a predictor of the risk of falling in elderly [26]. Comparative studies between the force platforms (stabilometry) and the WBB found no statistical difference between the measurements of center of pressure (CoP) coordinates [25,27,28], or in its accuracy [29]; as such, the WBB is considered a valid, reliable, and inexpensive instrument for research [25,30].…”

Motor imagery (MI) is the act of coding the mental aspect of an intended task without executing it. Fear consists of an anxiogenic response to a previous event, which provides a state of alertness to the individual in the face of a threat. These two conditions (imagery and fear) may modulate orthostatic postural control, but their combined effect is still unknown. To investigate whether cervical kinesthetic motor imagery induces modulations in postural control and in the fear of falling (FoF) sensation in healthy young adults. Participants (n = 20) were placed on the Wii Balance Board ® and oriented to perform and imagine three tasks for 60 s: (1) closed eyes; (2) cervical flexion; and (3) cervical inclination. The number of performed and imagined repetitions were recorded, and participants responded to a question at the end of each task regarding the FoF. There were four relevant effects: (1) there was no difference between the number of performed and imagined repetitions (p > 0.05) indicating similarities; (2) there was a greater sensation of FoF induced by kinesthetic MI tasks (p < 0.001); (3) there was a greater modulation of the center of pressure (mean velocity and amplitude) in the anteroposterior direction in phobic subjects (p < 0.05); and (4) there was no modulation between the non-phobic subjects in the anteroposterior direction (p > 0.05). The FoF during kinesthetic MI tasks may influence the orthostatic postural control, favoring the reduction in postural stability.

“…Since scales of clinical tests have clear boundary scores, Karthikeyan et al [42], Kim et al [43], İlçin et al [44] and Li et al [45] proposed that balance is considered as impaired when the score is 23 or below for BBS. Barry et al [37], Shumway-Cook et al [46], Lindsay et al [47] and Kwoka et al [48] recommend that it is considered a high risk if the time for TUG is greater than 13.5 s. Furthermore, in clinical judgments of the SPMSQ, there may be a risk of dementia if a subject answered three or more questions incorrectly in the test. We try to use these indicators as judgment criteria for categorizing fallers and non-fallers.…”

Abstract:In this paper, the Multiscale Entropy (MSE) analysis of acceleration data collected from a wearable inertial sensor was compared with other features reported in the literature to observe falling behavior from the acceleration data, and traditional clinical scales to evaluate falling behavior. We use a fall risk assessment over a four-month period to examine >65 year old participants in a community service context using simple clinical tests, including the Short Form Berg Balance Scale (SFBBS), Timed Up and Go test (TUG), and the Short Portable Mental Status Questionnaire (SPMSQ), with wearable accelerometers for the TUG test. We classified participants into fallers and non-fallers to (1) compare the features extracted from the accelerometers and (2) categorize fall risk using statistics from TUG test results. Combined, TUG and SFBBS results revealed defining features were test time, Slope(A) and slope(B) in Sit(A)-to-stand(B), and range(A) and slope(B) in Stand(B)-to-sit(A). Of (1) SPMSQ; (2) TUG and SPMSQ; and (3) BBS and SPMSQ results, only range(A) in Stand(B)-to-sit(A) was a defining feature. From MSE indicators, we found that whether in the X, Y or Z direction, TUG, BBS, and the combined TUG and SFBBS are all distinguishable, showing that MSE can effectively classify participants in these clinical tests using behavioral actions. This study highlights the advantages of body-worn sensors as ordinary and low cost tools available outside the laboratory. The results indicated that MSE analysis of acceleration data can be used as an effective metric to categorize falling behavior of community-dwelling elderly. In addition to clinical application, (1) our approach requires no expert physical therapist, nurse, or doctor for evaluations and (2) fallers can be categorized irrespective of the critical value from clinical tests.

RESUMOINTRODUÇÃO: Durante o processo de envelhecimento, a manutenção de uma adequada aptidão física é fundamental para o aumento da expectativa e da qualidade de vida. Atividades que combinam a dança com o meio aquático parecem ser adequadas a tal propósito, pois proporcionam a integração de diferentes habilidades como ritmo, coordenação espaço-temporal, força, resistência muscular e potência, estimulando a neuroplasticidade e proporcionando a manutenção de capacidades funcionais. Deste modo, avaliar os efeitos de tais atividades na funcionalidade e capacidade de manutenção do equilíbrio em populações de indivíduos com meia-idade e idosos é fundamental. Objetivo: Identificar os efeitos de um programa de exercícios baseados em passos de dança em meio aquático no equilíbrio e agilidade de indivíduos de 50 a 75 anos. MÉTODOS: 15 sujeitos de ambos os gêneros (63,93 ± 6,97 anos) foram submetidos a um programa de exercícios de dança em meio aquático, 2 vezes por semana, com duração de 50 minutos. No início e após 6 e 12 semanas os participantes foram submetidos aos testes de equilíbrio (Wii® balance board) e agilidade (American Alliance for Health, Physical Education, Recreation and Dance -AAHPERD). Análises de variância (ANOVA two-way e ANOVA one-way) foram aplicadas para testar as diferenças entre as avaliações e condições experimentais. O teste post hoc de Tukey foi aplicado para determinar onde as diferenças ocorreram. Os testes tiveram nível de significância de p ≤ 0,05. RESULTADOS: Foi identificada melhora na agilidade (p ≤ 0,05) sem mudanças na capacidade de manutenção do equilíbrio (p > 0,05). CONCLUSÃO: Exercícios baseados em passos de dança em meio aquático são eficazes para o ganho de agilidade, porém não influenciam a capacidade de manutenção do equilíbrio estático de indivíduos de 50 a 75 anos. Sendo assim, o programa pode ser utilizado como ferramenta terapêutica para reabilitação e manutenção de algumas capacidades funcionais. PALAVRAS-CHAVE: envelhecimento; fisioterapia; hidroterapia; dança. ABSTRACT INTRODUCTION:In the ageing process, maintaining physical fitness is essential for increased life expectancy and better quality of life. Exercises that combine dance moves and water practices seem to be adequate for such purpose, as they gather different skills like rhythm, space-time coordination, force, muscle strength and power, stimulating neuroplasticity and maintaining functional skills. Thus, it is important to assess the effects of such activities on functionality and balance maintenance ability in populations of middle-aged individuals. OBJECTIVE: To identify the effects of a physical program based on dance moves in water on balance and agility of individuals aged 50 to 75 years. METHODS: 15 subjects of both genders (63.93 ± 6.97 years) were submitted to a 50-minute physical program of dance moves in water, twice a week. The participants were submitted to the Wii® balance board test and the American Alliance for Health, Physical Education, Recreation and Dance (AAHPERD) agility test at program star...
