- ItemAcesso aberto (Open Access)Degree of thoracic kyphosis and peak torque of trunk flexors and extensors among healthy women(Sociedade Brasileira de Ortopedia e Traumatologia, 2014-06-01) Granito, Renata Neves; Aveiro, Mariana Chaves [UNIFESP]; Renno, Ana Claudia Muniz [UNIFESP]; Oishi, Jorge; Driusso, Patricia; Universidade Federal de São Carlos; Universidade Federal de São Paulo (UNIFESP)OBJECTIVE:The aim of this study was to analyze the effects of aging on the degree of thoracic kyphosis and peak torque of the trunk flexor and extensor muscles among women without a densitometric diagnosis of osteoporosis.METHODS:Thirty women were selected to make up three groups: young women (n = 10; 24.60 ± 2.27 years of age); adults (n = 10; 43.50 ± 2.88); and elderly women (n = 10; 62.40 ± 2.67). Bone mineral density (BMD), degree of thoracic kyphosis and peak torque of the trunk flexors and extensors were evaluated. Differences between the groups were evaluated using the Kruskal-Wallis ANOVA and Mann-Whitney U tests. Pearson's correlation coefficient was used to assess correlations between the variables. The significance level was taken to be 5% (p < 0.05).RESULTS:The elderly group presented a greater degree of thoracic kyphosis (p = 0.009) and lower peak torque of the trunk flexors and extensors than the young group. The adult group presented lower peak torque of the trunk than the young group. A negative correlation was observed between age and peak torque of the trunk flexors and extensors (p < 0.001), and a positive correlation between age and the degree of thoracic kyphosis (r = 0.58; p < 0.001). The elderly group presented higher values for the eccentric/concentric ratio of the peak torque for flexors (p = 0.03) and extensors (p = 0.02).CONCLUSION:This study suggests that physiological aging may be associated with a greater degree of thoracic kyphosis and lower muscle strength of the trunk flexors and extensors. Moreover, the elderly women showed a relative capacity for preservation of eccentric strength.
- ItemSomente MetadadadosEvaluation of physical capacity and quality of life in osteoporotic women(Springer, 2004-01-01) Lombardi Júnior, Imperio [UNIFESP]; Oliveira, Leda Magalhães de [UNIFESP]; Monteiro, Cristiano Ralo [UNIFESP]; Confessor, Yara Queiroga [UNIFESP]; Barros, Turíbio Leite de [UNIFESP]; Natour, Jamil [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Introduction: Osteoporotic vertebral fractures result in increased kyphosis angle, an alteration that may lead to disturbance in physical capacity. Objective: We sought to evaluate physical capacity and disability in a group of osteoporotic patients. Material and methods: Fifteen women with osteoporosis and vertebral fractures (G1), 20 women with osteoporosis without vertebral fractures (G2), and 20 control women (G3) were selected. the variables of physical capacity were measured using a treadmill. the patients spent 4 min standing quietly, 4 min walking at 3 km/h, and 10 min walking at 4 km/h. the SF-36 questionnaire was also applied. Results: the results showed that women with osteoporosis and vertebral fractures (G1) had increased kyphosis angle (median 60degrees), while the angle was 43.5degrees for G2 and 37degrees for G3. Oxygen consumption (VO2 (kg)), METS (metabolic equivalent), and energy expenditure (kcal/h) during the standing period were higher in G1 than in G2 (G1 vs G2, p=0.016, p=0.017, and p=0.012, respectively), whereas no difference in these parameters was observed between groups during the walking period. the energy expenditure during walking at 3 km/h and at 4 km/h showed a correlation with thoracic kyphosis in G1 (p=0.01 and p=0.017, respectively). No difference in SF-36 scores was observed between the three groups. Conclusion: Energy expenditure showed a correlation with the angle of thoracic kyphosis. Patients with or without osteoporosis showed the same energy expenditure during the walking period. the SF-36 score was similar for the three groups.
- ItemSomente MetadadadosEvaluation of pulmonary function and quality of life in women with osteoporosis(Springer, 2005-10-01) Lombardi Júnior, Imperio [UNIFESP]; Oliveira, Leda Magalhães de [UNIFESP]; Mayer, Anamaria Fleig [UNIFESP]; Jardim, José Roberto [UNIFESP]; Natour, Jamil [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Osteoporotic vertebral fractures generally result in an increased kyphotic angle, which in turn may lead to disturbances in pulmonary function. the objective of the present study was to evaluate pulmonary function and quality of life in a group of osteoporotic patients. Fifteen women with osteoporosis and thoracic vertebral fractures (group 1), 20 women with osteoporosis without vertebral fracture (group 2) and 20 control women (group 3) were submitted to spirometry using a Vitatrace-130 SL spirometer and to an SF-36 quality of life questionnaire. Women with osteoporosis and vertebral fractures showed an increased kyphotic angle (median=60 degrees) and decreased forced vital capacity (group 1 vs. group 2, P =0.020; group 1 vs. group 3, P =0.039) and forced expiratory volume in 1 s (group 1 vs. group 2, P =0.008; group 1 vs. group 3, P =0.014) when compared with women without vertebral fractures or osteoporosis. A negative correlation was observed between thoracic kyphosis and the predicted value of expiratory forced volume in 1 s ( r =-0.713, P =0.003). No differences in the quality of life were detected between the three groups studied. We conclude that women with thoracic vertebral fractures have an increased kyphotic angle and present a decrease in lung volume.
