“…Cangrussu et al (16) did not find significant differences between women with and without osteoporosis, for any variable of the force platform in bipodal support with eyes open. However, Burke et al (15) identified significantly higher postural oscillation in the eyes open task on the force platform on a stable surface in the group of women with osteoporosis. It is notable that they did not observe significant differences in the more challenging task (unstable surface).…”

“…A few studies have found linear and consistent relations between muscular strength and BMD (7,8) , while the majority have found inconsistent results (9)(10)(11)(12)(13) . Similarly, when the variable refers to postural balance, a few studies have shown an inverse relationship between greater postural oscillation and BMD (14,15) , while the majority of studies have not identified any relationship (9,11,12,16) . However, to determine correlations between BMD and muscular strength or postural balance in postmenopausal women, some measurement conditions of these variables have not yet been tested, such as the isokinetic peak torque of knee extensors and flexors on an isokinetic dynamometer, or stabilographic analysis of postural oscillation on a force platform under challenging conditions, such as semi-tandem or unipodal support.…”

Background: Postmenopausal women typically present loss of bone mineral density (BMD), muscular strength, and postural balance. However, there is no consensus in the literature on the correlation between these variables. Objectives: Our objective was to verify the correlation between BMD, isokinetic peak torque of knee extensors and flexors, and static postural balance in postmenopausal women. Methods: Fifty-one postmenopausal women underwent BMD evaluation through dual-energy X-ray absorptiometry (DXA) for four bone regions (lumbar spine, femoral neck, total hip, and trochanter). Muscular strength of knee extensors and flexors was evaluated in an isokinetic dynamometer at 60 and 180 degrees per second in the dominant lower limb. Static postural balance was evaluated on a force platform during five different tasks (bipodal eyes open, bipodal eyes closed, semi-tandem eyes open, semi-tandem eyes closed, and unipodal). Statistical analysis involved Spearman's correlation coefficient (rho). Results: There was no significant correlation between BMD and isokinetic peak torque of knee extensors and flexors. Approximately half (27 of 60) of the postural balance variables presented significant inverse correlations (p < 0.05) with BMD and of these, the majority (22 of 27) presented moderate correlation (rho between -0.49 and -0.30). Most correlations were for bipodal support tasks with eyes open and eyes closed. Conclusion: Greater postural oscillation in different balance tasks was correlated with lower BMD in postmenopausal women. Therefore, it is suggested that intervention protocols for women with impaired BMD, especially osteoporotic, consider balance training as part of rehabilitation.

“…Spherical markers with 15 mm of diameter were attached to the skin on reference anatomic spots. The photos were taken with the participants minimally dressed in order to detect the following spots 19 : ear tragus; seventh cervical vertebrae; third thoracic vertebrae (T3); acromion midpoint; anterior superior iliac spine; posterior superior iliac spine; femur trochanter; patellar medial facet; tibial tuberosity; knee lateral epicondyle; scapular lower angle; knee joint line; medial gastrocnemius line; calcaneal tendon and calcaneal base; lateral and medial malleolus. All were placed bilaterally, except seventh cervical vertebrae and T3.…”

| The aim of this study was to evaluate the effects of the Pilates method on the postural alignment and joint flexibility in healthy young females. Thirty-three women aged between 18 and 30 years (56.8±8.5 kg, 1.60±0.06 m, and 22.1±2.7 kg/m 2 ) having no prior knowledge of Pilates participated in this study. They were randomly allocated into two groups: control group (without intervention) and Pilates group (PG; mat Pilates, 20 sessions, twice a week). Pre and post-program evaluation procedures were performed by a blinded investigator and were characterized by photogrammetric postural analysis (Postural Assessment Software) and assessment of joint flexibility (Wells sit and reach test). A 2×2 Analysis of Variance was used for repeated measures in order to verify differences between pre-and post-measurements for both control group and PG. No significant differences were found between the groups, for all variables. The PG presented no differences in postural alignment after the program (p>0.05). However, the PG demonstrated a significant increase of 19.1% in flexibility (p=0.036). This study showed that a program of mat Pilates produces significant effects on joint flexibility. However, 20 sessions were not sufficient to cause static postural adaptations in healthy young women. , sem conhecimento prévio de Pilates. Todas deram entrada sequencial e foram alocadas aleatoriamente em dois grupos: grupo controle (GC; sem intervenção) e grupo Pilates (GP; Pilates em solo, 20 sessões, 2 vezes por semana). O processo de avaliação pré e pós-programa foi realizado por avaliador mascarado e caracterizado por avaliação postural fotogramétrica (programa SAPO) e avaliação da flexibilidade articular (teste de sentar e alcançar no banco de Wells). Utilizou-se uma Análise de Variância (ANOVA) 2X2 para medidas repetidas para se verificar diferenças entre momentos pré e pós-programa, para o GC e GP. Não foram encontradas diferenças significantes entre o GC e GP para todas as variáveis. O GP não apresentou diferenças na postura, após o programa (p>0, 05). Entretanto, o grupo GP apresentou um ganho significante de 19, 1% na flexibilidade (p=0, 036) no momento pós. O estudo demonstrou que um programa de Pilates aplicado em solo gera efeitos significantes na flexibilidade articular. Entretanto, vinte sessões parecem não ser suficientes para causar adaptações posturais estáticas em mulheres jovens sadias.

“…Characterization of evaluated conditions in the five tasks may contribute to various outcomes, assist evaluation and intervention programs for older women. However, it is quite pertinent to investigate differences on postural balance of women due to the neurophysiological changes imposed by the aging process and the appearance of diseases such as osteoporosis, which can impair balance and increase risk of falls 12 .…”

RESUMO O envelhecimento é um processo natural que acarreta mudanças intrínsecas e extrínsecas ao organismo. O objetivo é analisar cinco tarefas de equilíbrio postural em idosas através da Plataforma de força, correlacionando com o risco de quedas avaliado pelo teste Timed Up and Go (TUG). Participaram do estudo 43 idosos e 40 adultos jovens, todos do sexo feminino, que foram avaliadas em uma plataforma de força com um protocolo padrão: descalças, com os braços ao longo do corpo nas tarefas bipodal e semitandem, ambos olhos abertos e fechados, apoio unipodal utilizando o centro de oscilação postural (COP) e as velocidades nos eixos anteroposterior (Vel AP) e médio-lateral (Vel ML). Após 5 minutos de descanso, realizou-se o TUG. Os resultados mostraram que as idosas tiveram maior instabilidade postural (p<0.05) em relação às adultas jovens, e a tarefa que mais desafiou o equilíbrio foi o apoio unipodal COP 10,02 (cm2) Vel AP 3,00 (cm/s) e Vel ML 3,32 (cm/s), e as idosas tiveram um tempo médio no TUG de 9,01 segundos considerando um baixo risco de quedas. Conclusão: Idosas apresentam um maior déficit no equilíbrio em relação às jovens, sendo a tarefa de apoio UNP a que mais apresentou desafios no controle postural das duas populações. Idosas saudáveis apresentaram um baixo risco para as quedas, nenhuma correlação foi encontrada entre o equilíbrio postural através da plataforma de força e risco de quedas do TUG.
