- ItemAcesso aberto (Open Access)Efeitos da vibração mecânica de corpo inteiro sobre parametros neuromusculares e funcionais em mulheres osteopênicas na pós-menopausa(Universidade Federal de São Paulo (UNIFESP), 2016-10-25) Dutra, Milena Carrijo [UNIFESP]; Castro, Marise Lazaretti [UNIFESP]; http://lattes.cnpq.br/8253870907570489; http://lattes.cnpq.br/8198122434022424; Universidade Federal de São Paulo (UNIFESP)Mechanical loading stimulation of bone with physical exercise has been described in the literature as an important non-pharmacological method to prevent and develop the musculoskeletal system. Mechanical stimulation with low intensity and low frequency vibration has been evaluated as a new, effective and safe way to improve muscle strength and bone mineral density (BMD). In this study, lowintensity vibration platforms were developed to evaluate the effects of mechanical vibration on neuromuscular function and functional capacity in osteopenic postmenopausal women. This was a longitudinal case-control study conducted in 122 women divided into two groups matched for age, and ethnicity: 62 in the platform group (PG - 63.24 ± 9.84 years) and 60 in the control group (CG - 62.88 ± 7.87 years). Five times a week, during 20 minutes over 12 months, the volunteers in the PG stood still and barefoot on the platform which vibrated with a frequency of 60 Hz, intensity of 0.6g and amplitude < 1mm. The volunteers in the CG were followed up and instructed to maintain their usual physical activity. At the beginning and end of the study, isometric muscle strength was assessed by dynamometry: hip flexors (HF), back extensors (BE) and right handgrip (RH) stMechanical loading stimulation of bone with physical exercise has been described in the literature as an important non-pharmacological method to prevent and develop the musculoskeletal system.

The volunteers in the CG were followed up and instructed to maintain their usual physical activity. At the beginning and end of the study, isometric muscle strength was assessed by dynamometry: hip flexors (HF), back extensors (BE) and right handgrip (RH) strength. Dynamic upper limb strength was assessed with elbow flexion (EF). Additional, tests included the functional reach test (RT), mobility (TUG), and static balance, assessed with unipedal stance test (UST). The results showed that after 12 months, the PG presented significant (p < 0.05) in (HF ± 36.7 %), (BE ±36.5% and RH ± 4.4%), and dynamic (EF ± 22.8%) muscle strength. The RT improved by (9.9%) and the (UST by 6.8%). In the CG there was a significant decrease of -3.9 % in RH isometric strength. There was an improvement on the TUG reflected by a reduction of -9.2 % in execution time. We conclude that low-intensity vibration was effective in improving muscle strength in the upper and lower limbs, balance, and mobility in postmenopausal woman.rength.

- ItemSomente MetadadadosThe P18 component of the median nerve SEP recorded from a posterior to anterior neck montage(Elsevier B.V., 2012-10-01) Giuliano, L. M. P. [UNIFESP]; Nunes, K. F. [UNIFESP]; Manzano, G. M. [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Objective: To investigate the P18 component in the posterior to anterior neck montage after median nerve stimulation.Methods: Somatosensory evoked potentials, through electrical wrist stimulation, were collected. in 12 subjects, the presence of the P18 component was evaluated in the posterior to anterior neck montage. in 10 subjects, the effects of simultaneous vibration of the hand were evaluated. in five subjects, responses after double-pulse stimulation (ISI 20 ms) were evaluated.Results: the P18 component was identified in all subjects. Vibration reduced the amplitude of all components except the P18 and N18. Double-pulse stimulation reduced the amplitude of the P18 and the N18 components without significantly changing the amplitude of the other components.Conclusions: the posterior to anterior neck montage allows for recording the P18 component. the amplitude reduction of all components during vibration, except N18 and P18, is interpreted as reflecting inhibitory activities at the cuneiform nucleus and at the segmental dorsal horn of the spinal cord, respectively. the reduction in the P18 component after double-pulse stimulation is compatible with previous observations on the positive component of cord dorsum potentials.Significance: Studying this component may add to the knowledge of the function of the spinal cord in humans.

- ItemEmbargoUso de dispositivo vibratório para tratamento de mulheres com transtorno da dor gênito-pélvica/penetração(Universidade Federal de São Paulo, 2024-09-06) Santos, Bianca Bispo dos [UNIFESP]; Silva, Ivaldo da [UNIFESP]; http://lattes.cnpq.br/9948402316193744; http://lattes.cnpq.br/5264800914606074Objetivos: analisar os efeitos do massageador Peridell® no tratamento do transtorno de dor gênito-pélvica/penetração. Métodos: 16 mulheres com diagnóstico de Transtorno da dor gênito-pélvica/penetração (DGP) foram selecionadas para participar desta pesquisa. Elas foram divididas igualmente em dois grupos: grupo intervenção (GI) e o grupo controle (GC). No GI, as voluntárias participaram do protocolo com a vibração terapêutica do Peridell® e também pela massagem perineal. No grupo GC, as voluntárias fizeram apenas a massagem perineal. Para avaliar os resultados foi utilizado o questionário índice de função sexual feminina, avaliação do assoalho pélvico e a escala verbal numérica (EVN). Resultados: ambos os grupos obtiveram diminuição da dor na EVN, mas o GC obteve diferença estatisticamente positiva. Também tiveram melhora da função sexual, enquanto o grupo GI teve aumento positivo, com diferença estatística nos domínios de orgasmo, dor e escore total quando comparado ao GC. Conclusão: a vibração por meio do Peridell® pode ser benéfica para o tratamento da dor gênito/pélvica.
