CORRELATION OF THE SAGITTAL BALANCE WITH POSTURAL ANALYSIS OF THE PELVIS AND LUMBAR SPINE.

Objective: Evaluate and correlate the sagittal balance parameters with the postural of the pelvis and lumbar spine. Methods: 80 individuals of both sexes, aged between 20 and 35 years, were evaluated. Biophotogrammetry was done with the SAPO software program. Measurements of the sagittal balance parameters were obtained by analyzing a lateral view panoramic radiography of the vertebral column, in which the anatomical points of reference were digitally marked. The calculation of the angles was done automatically by the Keops program. Results: In Keops assessment, 17.5% of the sample had high pelvic incidence angles (> 60°), 31.5% had low pelvic incidence angles (< 45°), and 51.2% had medium pelvic incidence angles (between 46° and 59°). SAPO showed 12,5% lordosis, 40% retroversion, and 47,5% normal curvature. In the right lateral view, pelvic incidence angle had a moderate and positive correlation with vertical alignment of the trunk and with vertical alignment of the body, and a negative and moderate correlation with horizontal alignment of the pelvis. Conclusion: Differences were found between vertical alignment measurements from the postural evaluation system (SAPO). A positive correlation was found between PI from Keops and pelvic anteversion from SAPO. Level of Evidence II; Prospective Study.

Objetivo: Avaliar e correlacionar o equilíbrio sagital com parâmetros posturais da pelve e coluna lombar. Métodos: Foram avaliados 80 indivíduos de ambos os sexos, com idade entre 20 e 35 anos. A biofotogrametria foi realizada com o software SAPO. As medidas dos parâmetros do equilíbrio sagital foram obtidas pela análise de uma radiografia panorâmica em perfil da coluna vertebral, na qual os pontos anatômicos de referência foram marcados digitalmente. O cálculo dos ângulos foi feito automaticamente pelo programa Keops. Resultados: Na avaliação Keops, 17,5% da amostra apresentavam ângulos de incidência pélvicos altos (> 60°), 31,5% tinham ângulos de incidência pélvicos baixos (< 45°) e 51,2% apresentavam ângulos de incidência pélvicos médios (entre 46° e 59°). O SAPO apresentou 12,5% de lordose, 40% de retroversão e 47,5% de curvatura normal. Na vista lateral direita, o ângulo de incidência da pelve apresentou correlação moderada e positiva com o alinhamento vertical do tronco e com o alinhamento vertical do corpo e negativa e moderada com o alinhamento horizontal da pelve. Conclusão: Foram encontradas diferenças entre as medidas de alinhamento vertical do sistema de avaliação postural (SAPO). Uma correlação positiva foi encontrada entre IP de Keops e anteversão pélvica de SAPO. Nível de Evidência II; Estudo Prospectivo.

Physical and pulmonary capacities of individuals with severe coronavirus disease after hospital discharge: A preliminary cross-sectional study based on cluster analysis.

OBJECTIVE: This study aimed to analyze the physical and pulmonary capacities of hospitalized patients with severe coronavirus disease and its correlation with the time of hospitalization and complications involved. METHODS: A total of 54 patients, aged ≥18 years of both sexes, were evaluated 2-4 months after hospital discharge in São Paulo, Brazil. The physical characteristics analyzed were muscle strength, balance, flexibility, and pulmonary function. The K-means cluster algorithm was used to identify patients with similar physical and pulmonary capacities, related to the time of hospitalization. RESULTS: Two clusters were derived using the K-means algorithm. Patients allocated in cluster 1 had fewer days of hospitalization, intensive care, and intubation than those in cluster 2, which reflected a better physical performance, strength, balance, and pulmonary condition, even 2-4 months after discharge. Days of hospitalization were inversely related to muscle strength, physical performance, and lung function: hand grip D (r=-0.28, p=0.04), Short Physical Performance Battery score (r=-0.28, p=0.03), and forced vital capacity (r=-0.29, p=0.03). CONCLUSION: Patients with a longer hospitalization time and complications progressed with greater loss of physical and pulmonary capacities.

Confiabilidade das mensurações de testes isocinéticos para articulação do tornozelo / Reliability of isokinetic test measurements for ankle joint

O teste isocinético do tornozelo tem uma grande relevância, já que é possível estabelecer protocolos com velocidades e modos de contração semelhantes aos das atividades funcionais e esportivas. Desta forma, são necessários estudos que mostram a confiabilidade desta ferramenta para auxiliarem na prevenção de lesões do tornozelo. Objetivo: Elaborar uma revisão de literatura sobre estudos que abordaram a confiabilidade de testes isocinéticos da articulação do tornozelo. Métodos: A busca na literatura foi realizada nas bases de dados Pubmed, Lilacs, Pedro, Scielo, Scopus e Cochrane com os descritores científicos ankle e isokinetic e reliability. Foram identificados 34 artigos, 4 foram excluídos por não estudarem humanos e 27 foram incluídos (10 referentes à confiabilidade de testes isocinéticos para inversores e eversores do tornozelo e 17 referentes à confiabilidade de testes para flexores-plantares e dorsiflexores). Resultados: A confiabilidade da avaliação isocinética dos flexores-plantares e dorsiflexores tem sido descrita para diferentes dinamômetros, posições, modos e populações. Os valores de coeficientes de correlação intraclasse variam de 0,55-0,98; e a de eversores e inversores, variam de 0,54-0,99, classificados na faixa de satisfatório a excelente. Conclusão: Os protocolos isocinéticos da articulação do tornozelo devem ser elaborados de acordo com a musculatura recrutada e com a população (com presença ou não de patologia).

Ankle isokinetic tests are importance because establish protocols with velocities and modes of contraction similar to functional and sport activities. Thus, studies that show the reliability of this tool are needed to help the ankle injury prevention. Objective: To develop a literature review about studies that show the reliability of ankle isokinetic test. Methods: The literature search was conducted in Pubmed, Lilacs, Peter, Scielo, Scopus and Cochrane with key words: isokinetic and ankle and reliability. 34 articles were identified, 4 were excluded because they did not study humans and 27 were included (10 about the reliability of ankle inverters and everter isokinetic tests and 17 about the reliability of tests for ankle flexor-plantar and dorsiflexors). Results: The reliability of isokinetic test has been described for different dynamometers, positions, modes and populations. The values of intraclass correlation coefficients ranged from 0.54 to 0.99, which were considered satisfactory to excellent. Conclusion: Ankle isokinetic protocols must be prepared in accordance with the recruited muscles and the population (with or without pathology).
