home-based exercise tele-rehabilitation after covid-19

Conditions: Post SARS-CoV2 (COVID-19)

Summary: the coronavirus disease 2019 (covid-19) pandemic has resulted in catastrophic infections and fatalities across the nation. many older veterans with comorbidities are especially vulnerable to complications and poor recovery. this award will investigate the effect of a novel, home-based, supervised, group exercise tele-rehabilitation in veterans recovered from covid-19 on cardiopulmonary and physical function.

there is an urgent need to understand the lasting impact of covid-19 on the cardiopulmonary system to improve physical function and prevent long-lasting disability. pertinent knowledge gaps regarding the post-recovery physiology driving any impairments need to be addressed to improve the quality of life in veterans with prior sars-cov-2 infection. further, it is important to devise successful rehabilitation strategies that can be safely conducted in a veteran's home. hence, the investigators propose to utilize va video connect to deliver a home based, supervised group exercise program to veteran covid-19 survivors. the objective of this exercise trial is to determine the influence of covid-19 on cardiorespiratory fitness, pulmonary and physical function and to investigate the effect of a home-based exercise tele-rehabilitation on these outcomes. the study design includes rural and urban sites and investigators with a history of va rehabilitation collaboration. moreover, the investigators will explore healthcare disparities related to covid-19 which are associated with functional decline and may affect sustainability of exercise rehabilitation strategies deployed, if necessary, under social distancing restrictions.
