Symptoms such as impairment of postural balance, mobility and muscle strength can last up to 12 months post COVID-19 hospitalization, need to be better understood, as they can have repercussions in activities of daily living. What happens to postural balance, mobility, and handgrip strength of COVID-19 patients after hospitalization? A prospective cohort study was conducted with patients of both sexes, aged ≥18, admitted to hospital diagnosed with COVID-19. Outcomes were assessed at 1, 4, 6, and 12 months post-discharge, including: postural balance - Brief-Balance Evaluation Systems Test, mobility - Timed “Up & Go” Test, and handgrip strength – dynamometry. Prevalence values of impaired postural balance and mobility and lower-than-expected handgrip strength were calculated by point estimate and 95 % confidence interval. Shapiro-Wilk test showed that our data did not have a normal distribution, so the Friedman Test and the test of proportions were used for the statistical analysis. Performance on postural balance was improved after four months of hospital discharge, but the improvement in mobility and handgrip strength only occurred after six months. After six months of discharge, the proportion of individuals with impairments began to decrease. A higher prevalence of impairments in postural balance and mobility occurred at one month post-discharge, which reduced over time. However, the values of impairments for postural balance and mobility were still high after 12 months of follow-up. There was a high prevalence of postural balance and mobility impairment 1 month after discharge, which was still high 12 months after discharge. The prevalence of lower-than-expected handgrip strength demonstrated limited change over time. Results highlight the need for assessment of postural balance, mobility and hand grip strength in post COVID-19 related hospitalization protocols, and long-term physical therapy interventions to address these impairments when identified to improve long term outcomes. •There was a high prevalence of mobility impairment after COVID-19 hospitalization.•Postural balance impairment can last one year after hospitalization due to COVID-19.•Balance and mobility screening are important after hospital discharge.•Lower muscle strength was observed after COVID-19 hospitalization.
