“…On the other hand, it has been demonstrated that there is a connection between walking balance and strength [80] and that sarcopenia influences walking balance [81]. A study with older adults with mild to moderate frailty improved their CRF but at a modest level [82].…”

“…The main finding of this study is that the BMD of the weight-bearing bones (BMDtoes) were significantly higher than the BMD of the non-weight-bearing bones (BMDthumbs). Weight-bearing activities which result in limb loading, such as walking, running, and close-chain kinetic movements [51][52][53], could provide a very potent osteogenic stimulus in PLWH, and is, therefore, bone protective. Consequently, weight-bearing activities could have beneficial effects on bone health in PLWH and explain why a previous study found that physical activity level is a major determinant of bone mass in postmenopausal women [54].…”

“…An active lifestyle should increase lean muscle mass [53] and boost physical activity which recruits the skeletal muscles and increases the loading traction on the bones thereby increasing shear strain that activates osteoblastic activities [66] in the presence of putative mediators such as nitric oxide, prostaglandins E (PGE) and (PGI) I, sclerostin, Insulin-like growth factor (IGF's), Transforming growth factor beta (TGFβ), Receptor Activator of Nuclear Factor-kappa B-Ligand (RANK-L), and osteoprotegerin (OPG). Shear stress generated with physical exercises, involving skeletal muscle contraction, induces the production of nitric oxide [67].…”

Background: Biomechanical loading exerts an osteogenic stimulus; thus, bone mineral density(BMD) may vary in weight-bearing and non-weight-bearing bones. Therefore, weight-bearing activities could modulate sex-, HAART- and HIV-related BMD loss. Method: A cross-sectional observational study of 503 people living with HIV (PLWH) selected by convenience sampling at Enugu State University Teaching Hospital, Nigeria, was conducted from September 2015 to September 2016. The BMD of toe or weight-bearing(BMDtoe) and thumb or non-weight-bearing(BMDthumb) bones were measured with Xrite 331C densitometer and compared using independent t-test. Impact of the risk factors (age, weight, body mass index-BMI, duration of HIV, height and types of HAART) of bone loss and their relationships with the BMD were compared across the sexes using multivariate, and univariate regression analyses, at p<0.05,two-tailed. Result: Participants comprised of females(378/75.1%), males(89/17.7%) and others(36/7.16%) without gender specificity, with mean age=37.2±9.79years, and BMI=25.6±5.06kg/m. HAART-experienced participants’ (352/69.98%) mean HAART-exposure duration was 4.54±3.51years. BMDtoe(-0.16±0.65g/cm3) was higher(p<0.05) than BMDthumb(-0.93±0.44g/cm3), and differed across the BMI classes (p=0.000003;d=0.998), and was accounted for in post hoc analysis by normal weight versus underweight BMI classes (p=<0.001). BMDtoe was positively correlated with height (r=0.13,r2=0.0169;p<0.05), and males were taller than females(p<0.001). Females accounted for 90%(9/10) cases of osteopenia and 71.43%(5/7) osteoporosis. Males were older(p=0.002) while females had greater BMI (p=0.02), lower median BMDtoe(p=0.005) and BMDthumb (p=0.005). Conclusion: Higher BMD in weight-bearing bones, and lower BMDtoe in underweight (sub-optimal loading) BMI class suggest a role for osteogenic stimulus and fat metabolism in bone loss. Females being younger/heavier, would have greater loading/osteogenic stimulus reinforced by lesser age-related BMD changes. Males being taller would have greater bone marrow adipose tissue that promote osteogenesis through paracrine mechanisms. Therefore, higher BMD in males should be partly explained by height-related metabolic surrogates and sex-hormonal differences. Greater BMD In females’ weight-bearing bones implies that loading ameliorates physiological tendencies towards lower BMD.

“…Além disso, fatores fisiológicos contribuem no metabolismo de recuperação do tecido musculoesquelético. A redução sérica de hormônios ovarianos pode impactar na recuperação de massa muscular, devido a sua ação no sistema musculoesquelético, interferindo na força e área da fibra muscular [20,21] e isso possui relação direta com a idade reprodutiva na vida de uma mulher. Talvez, mulheres no período menacme possam apresentar uma boa recuperação funcional por uma boa resposta musculoesquelética, o que podemos hipotetizar pelo resultado satisfatório do presente estudo.…”

Introdução: Após a cirurgia para câncer de mama, algumas complicações podem levar a restrições da amplitude de movimento (ADM), dor e impacto negativo na realização das tarefas de vida diária. Neste contexto, a fisioterapia é importante na recuperação da funcionalidade. Objetivo: Avaliar o efeito da fisioterapia na amplitude de movimento, na intensidade de dor e no desempenho funcional do membro superior após a cirurgia para câncer de mama de mulheres no menacme. Métodos: Ensaio clínico não controlado, considerando mulheres que realizaram cirurgia para câncer de mama associada a linfonodectomia axilar. Foram avaliados a ADM pela fleximetria, intensidade de dor pela escala visual analógica (EVA) e o desempenho funcional pelo questionário “deficiência do ombro braço e mão” (DASH). Resultados: Após as 10 sessões de fisioterapia, foi observado aumento significativo da ADM de todos os movimentos, diminuição da intensidade de dor de 4,09 ± 2,51) para 2,54 ± 2,18, (p = 0,04), e dos escores do DASH de 35,31 ± 17,23 para 17,75 ± 13,09, (p = 0,001), indicando significativa melhora do desempenho funcional. Conclusão: A abordagem fisioterapêutica foi satisfatória em melhorar a ADM, intensidade de dor e o desempenho funcional em mulheres na pré-menopausa. Contudo, acompanhamento por mais longo prazo e incrementar os exercícios podem trazer melhora adicional.
