Inspiratory muscle training with threshold or incentive spirometry: Which is the most effective?

Inspiratory muscular training (IMT) increases the respiratory muscle strength, however, there is no data demonstrating its superiority over the incentive spirometry (IS) in doing so. Values of muscle strength after IMT (Threshold IMT(®)) and by the IS (Voldyne(®)) in healthy females was compared. Subjects (n=40) were randomly divided into control group (CG, n=14), IS group (ISG, n=13) and threshold group (TG, n=13). PImax was measured before (pre-IMT), at 15 and 30 days of IMT. There was an increase in PImax of the TG at 15 days (p<0.001) and 30 days of IMT (p<0.001). The same occurred with the ISG, which increased the PImax at 15 days (p<0.001) and 30 days of training (p<0.001). After 30 days of IMT, the TG presented a PImax which was significantly higher than ISG and the CG (p=0.045 and p<0.001, respectively). It can be concluded that IMT by threshold was more effective in increasing muscle strength than the Voldyne.

Avaliação da força de preensão palmar e dos volumes pulmonares de pacientes hospitalizados por condições não cirúrgicas

AIMS: The aim of this investigation was to analyzehandgrip strength and lung volumes in hospitalized patients. METHODS: This cross-sectional study enrolled subjects aged between 30 and 80 years of both genders and hospitalized under non-surgical conditions for at least 48 hours (Hospitalized Group) and healthy subjects accessed in a sport club (Control Group) in Santa Cruz do Sul, Rio Grande do Sul state, Brazil. Forced vital capacity, expiratory volume in the first second, expiratory volume in the first second /forced vital capacity relation, expiratory flow peak, and forced expiratory flow between 25% and 75% of vital capacity were evaluated. The handgrip strength was evaluated throught hand dinamometry. RESULTS:A total of 32 subjects were evaluated, being 16 in each group. They matched in age (p=0.183), height (p=0.685), weight (p=0.105) and body index mass (p=0.157) in both groups. The Hospitalized Group had a median hospital stay of 9.5 days (7-15; minimum 3, maximum 17). When compared to the Control Group, the Hospitalized Group had a reduction in forced vital capacity (p less than 0.001), expiratory volume in the first second (p less than 0.001), expiratory volume in the first second /forced vital capacity relation (p=0.006), peak expiratory flow (p less than 0.001) and forced expiratory flow between 25% and 75% of vital capacity (p less than 0.001), as well as in the handgrip force (p=0.001). CONCLUSIONS: The hospitalized subjects showed decrease in handgrip and lung volumes.

CORRELAÇÃO ENTRE FORÇA DE PREENSÃO PALMAR E DESEMPENHO NO TESTE TIMED UP AND GO EM IDOSOS INSTITUCIONALIZADOS

Introducao: O envelhecimento produz uma perda progressiva das aptidoes funcionais do organismo, principalmente pelo declinio das habilidades motoras, que resultam na perda da independencia e da autonomia, reduzindo muito a qualidade de vida dos idosos. Objetivos: Pesquisar a correlacao entre a forca de preensao palmar (FPP) e o desempenho no teste Timed Up Go (TUG) em idosos institucionalizados. Metodologia: Estudo quantitativo, observacional exploratorio de grupo. Amostra constituida por idosos residentes em Instituicao de Longa Permanencia, onde foram avaliados as variaveis, genero, peso, altura, IMC, teste TUG e FPP, buscando uma possivel correlacao entre o desempenho funcional pelo TUG e FPP. Resultados: Foram avaliados 20 idosos (9 homens e 11 mulheres), com media de idade 69,87 ± 9,11 anos. Os resultados entre homens e mulheres nao se diferenciaram quanto as variaveis analisadas, com excecao da FPP em mao nao-dominante, onde mulheres apresentaram menores valores. O principal achado foi a presenca de correlacao negativa de poder estatistico medio entre as variaveis no Teste TUG x FPP de mao nao-dominante (r=-o,690; p=0,013) e mao dominante (r=-0,649; p=0,005). As mulheres do estudo apresentaram maior tempo de institucionalizacao (6,3 ± 5,1 anos) em relacao aos homens (4 ± 3,8anos). Conclusao: Estudos relacionando variaveis referentes as alteracoes motoras no envelhecimento sao fundamentais para o avanco de evidencias cientificas que possibilitem nortear com maior precisao acoes fisioterapeuticas preventivas e reabilitadoras. Ao contribuirem para a ciencia, estarao beneficiando cada vez mais a populacao idosa.
