RESUMO

The objectives of this study were to determine whether there were differences in handgrip strength and functional mobility between patients with cystic fibrosis (CF) and healthy controls with regard to sex and to ascertain whether these differences were related to lung function. Thirty-eight patients with CF (21 women) and 38 healthy controls aged 18-65 years were included. Muscle weakness and functional mobility were assessed through handgrip strength; walking speed; and time, velocity, and power derived from a single sit-to-stand (STS) test. Patients with CF showed differences for STS variables and walking speed but not for handgrip strength, compared with healthy controls. Considering sex differences, female patients showed differences for all variables analyzed while males with CF only exhibited differences for STS variables, compared with healthy controls. Females with CF showed moderate relationship between muscle weakness, functional mobility, and lung function (|r| = 0.45-0.49; p ≤ 0.05) whereas no relationships were observed for males with CF. The influence of chronic infection with Pseudomonas aeruginosa and pancreatic insufficiency on muscle weakness and functional mobility was similar in both sexes. Differences in muscle strength and functional mobility were predominantly observed in females with CF. These results suggest an important effect of sex gap on muscle weakness and functional mobility in patients with CF. Novelty The influence of sex gap on muscle weakness in CF has been shown. Muscle weakness was predominantly observed in females with CF.

RESUMO

The objectives of this systematic review were to analyse existing evidence on the efficacy of smartphone devices in promoting physical activity (PA) in patients with chronic obstructive pulmonary disease (COPD) and to identify the validity and precision of their measurements. A systematic review was undertaken across nine electronic databases: WOS Core Collection, PubMed, CINAHL, AMED, Academic Search Complete, Cochrane Central Register of Controlled Trials, SciELO, LILACS and ScienceDirect. Randomized and non-randomized controlled clinical trials were identified. To obtain additional eligible articles, the reference lists of the selected studies were also checked. Eligibility criteria and risk of bias were assessed by two independent authors. A total of eight articles met eligibility criteria. The studies were focused on promoting PA (n  =  5) and the precision of device measurements (n = 3). The effectiveness of smartphones in increasing PA level (steps/day) at short and long term is very limited. Mobile-based exercise programs reported improvements in exercise capacity (i.e. incremental Shuttle-Walk-Test) at short and long term (18.3% and 21%, respectively). The precision of device measurements was good-to-excellent (r = 0.69-0.99); however, these data should be interpreted with caution due to methodological limitations of studies. The effectiveness of smartphone devices in promoting PA levels in patients with COPD is scarce. Further high-quality studies are needed to evaluate the effectiveness of smartphone devices in promoting PA levels. Registration number: CRD42016050048.
