    (Universidade Federal de São Paulo (UNIFESP), 2017-09-19) Freire, Jaqueline de Mesquita [UNIFESP]; Vidotto, Milena Carlos [UNIFESP]; http://lattes.cnpq.br/0334734747375995; http://lattes.cnpq.br/7592694904984273; Universidade Federal de São Paulo (UNIFESP)
    Adolescent idiopathic scoliosis (AIS) is characterized as a three- dimensional spine deformity, with a still unknown etiology, and its onset generally at puberty. Scoliotic deformities occur with physical, postural and respiratory changes. Recent studies point out that postural changes may influence cardiovascular autonomic function. Objectives: To evaluate heart rate variability (HRV) in resting in patients with AIS compared to healthy adolescents. Investigate the association between HRV, spinal angulations and lung function. Materials and Methods: This was a cross-sectional study with convenience sample of patients with AIS, of both sexes, aged 10 to 18 years, in the preoperative period. The study consisted of 66 participants, 34 patients with AIS in the scoliosis group (SG), who were chosen for conservative or surgical treatment and 32 healthy adolescents in the control group (CG). These patients underwent anthropometric evaluation, Cobb angle measurement, respiratory function evaluation and HRV at rest evaluation, where linear and non-linear indexes were recorded. Results: HRV presented a statistically significant difference in the linear index NN50 (p <0.001) between the analyzed groups. Patients with AIS presented reduced values of FVC, FEV1 and FEF 25-75%. Moderate correlations were found between HRV and lung function, as well as between thoracic Cobb angles and pulmonary function. Conclusion: Our results demonstrate that AIS role reduced HRV in linear indexes in the time domain for an NN50 variable, suggesting reduced parasympathetic modulation. Major spinal angulations are associated with worsening of pulmonary function in patients with AIS, as well as pulmonary function is also associated with HRV variables, showing that chest deformity and a pulmonary function may influence HRV in patients with AIS

    Reabilitação cardíaca não supervisionada baseada em caminhadas progressivas melhora endurance muscular respiratória após infarto agudo do miocárdio - ensaio clínico controlado e randomizado
    (Universidade Federal de São Paulo (UNIFESP), 2017-08-22) Garcia, Bruna Caroline Matos [UNIFESP]; Guizilini, Solange [UNIFESP]; http://lattes.cnpq.br/1563905009199506; http://lattes.cnpq.br/3927525142193704; Universidade Federal de São Paulo (UNIFESP)
    The purpose of this study was to: evaluate respiratory muscle strength and endurance in patients recently suffering myocardial infarction (MI) at inpatient period and investigate the effects of a home-based walking program on respiratory strength and endurance in post-MI patients with low risk. Methods: Patients were randomized into: Usual Care Group (UCG) entailing regular care (n=23); and Intervention group (IG) entailing an outpatient home-based walking program (n=31). Healthy subjects gender and age-matched served as a control group for respiratory endurance variables. Respiratory muscle strength was evaluated through maximal inspiratory pressure (MIP) and endurance during the inpatient period, 15-days and 60-days after MI. Submaximal functional capacity was determined by 6-minute walk test (6MWT) at hospital discharge and 60 days after MI. Results: Both groups showed impaired inspiratory muscle strength at hospital discharge. When compared with healthy subjects, post MI patients had worse respiratory muscle endurance pressure (PTHMAX= 73.02 ±8.40 vs 44.47±16.32, p<0.05) and time (Tlim= 324.1±12.2 vs 58.7±93.3, p<0.05). Only the IG showed a significant improvement in MIP and PTHMAX in 15 days and 60 days after MI (p<0.05). When comparing groups, the IG achieved higher values for MIP, PTHMAX and Tlim 15 and 60 days after MI (p<0.01). The 60-day assessment revealed that the 6MWT distance and level of physical activity was significantly higher in the IG compared to the UCG. Conclusion: Low riskxii patients recently suffering a MI demonstrate impaired MIP and respiratory endurance compared to healthy subjects. A home-based walking program improved respiratory endurance and functional capacity.
