Effects of social distancing provoked by COVID-19 pandemic in the functional capacity and cognitive function in nonagenarians and centenarians.

INTRODUCTION: Due to the rapid advance of coronavírus SARS-CoV-2 (COVID-19) pandemic in 2020, social distancing was the main way to reduce the transmission of the virus. Although this measure was efficient and necessary, the social distancing had severe consequences for physical function, mainly in older individuals. Thus, the aim of this study was to investigate the effects of social distancing in the functional and cognitive capacity of community-dwelling oldest-old adults. METHODS: The present study is part of a larger prospective cohort study. Fifteen participants aged 90 years old or older were assessed in the 8-foot-timed-up-and-go test (8-footTUG), sit-to-stand-up test (STS), handgrip strength test (HGS), Mini Mental State Examination (MMSE), Katz Index and Lawton Scale before and after one year of social distancing. RESULTS: A significant worsening in the 8-footTUG and MMSE score was observed, while there were no significant changes in the other variables. When analyzing the decreases in relation to previous functional capacity, it was observed that individuals categorized as dependent by STS cut-off points had the worst decreases in functional capacity. CONCLUSION: The social distancing provoked by COVID-19 pandemic negatively affected the 8-footTUG and cognition. Moreover, individuals dependents showed greater decline in their functional capacity.

Acute effects of different proprioceptive neuromuscular facilitation stabilization techniques on the balance of elderly women.

AIM: To compare the acute effects of rhythmic stabilization (RS) and stabilizer reversal (SR) techniques of PNF on the balance of sedentary elderly women. METHODS: Women aged (≥70) were allocated into three groups: RS, SR and control (CR). The experimental groups (RS and SR) performed balance exercises with the addition of rhythmic stabilization techniques (RS group) or with stabilizers reversal (SR group) for 15 min. The CR group performed the exercises without adding the PNF stabilization techniques. Participants performed the Time Up and Go (TUG) test, the Functional Reach Test (FRT) and static and dynamic stabilometry pre and post intervention. Kruskal-Wallis and Mann-Whitney tests were used for comparison between groups and post hoc analysis, respectively, with p ≤ 0.05. For the effect size measurements, the r for Wilcoxon and Mann-Whitney signal were used. RESULTS: For functional tests intra-group analysis, a reduction in TUG time and an increase in FRT range (p ≤ 0.05) were observed in RS e SR groups. Stabilometry analysis showed a significant difference only for the RS group, with reduced average velocity of the centre of pressure (COP), and an increased in the left foot pressure. CONCLUSIONS: A single RS or SR session reduced the TUG time and the range distance in the FRT in elderly women. A single session of the RS technique was also able to reduce the mean velocity of the COP and the maximum pressure on the left foot. IMPACT: This study shows an easy-to-apply methods without additional materials that can help prevent falls in the elderly.
