Impacts of Remote Physical Exercises on Functional Status and Mobility among Community-Dwelling Pre-Disabled Seniors during the Covid-19 Lockdown

ObjectivesTo assess whether remote physical exercise interventions helped maintain function in daily life, level of physical activities, basic mobility and frailty status in pre-disabled seniors during the first Covid-19 lockdown.DesignThis is an interventional study conducted from May 2020 to May 2021.SettingCommunity-dwelling older adults in 2 Canadian cities.Participants84 pre-disabled seniors.Intervention12-week physical exercise programs (1 hour/ 3 times/ week) in kinesiologist-guided groups using Zoom or phone-supervised individual booklet-based home-program (n=44) vs. Control (usual life habits; n=40).MeasurementsFunctional status in daily activities (OARS scale); Daily level of aerobic (TAPA-1) and strengthening/flexibility (TAPA-2) physical activities; Basic mobility abilities (SPPB: balance, lower limbs strength, walking speed; Timed Up-and-Go) and Frailty (SOF index) were assessed at baseline and at 3, 6, 9 and 12-month follow-ups.ResultsThe participants' mean age was 78.5 +/- 7.2 and 76.5 % were women. There was a group * time effect for the OARS scale (p=0.02), the TAPA-1 (p=0.06) and the TAPA-2 (p=0.007) scores. For these outcomes, scores significantly improved during the first 3 months of follow-up and then stabilised in the intervention group whereas they remained constant in the control group over time. There was an overall time effect for the SPPB (p=0.004), the 4-m walking speed (p=0.02) and for the SOF index (p=0.004), with no between-group differences. Finally, no effect was observed for the TUG.ConclusionRemote home-based physical exercise interventions and monitoring during the first Covid-19 lockdown seemed to have helped maintain seniors' level of physical activities without impacting on basic mobility abilities. Further studies are needed to identify parameters of remote exercise programs that can improve daily function and mobility in this population.

Automated summary

Remote physical exercise interventions during the first Covid-19 lockdown helped maintain function, physical activities, basic mobility, and frailty status in pre-disabled seniors. Further studies are needed to identify parameters of remote exercise programs that can improve daily function and mobility in this population.
