Insights
Long COVID can cause lasting lung issues. Many hospitalized patients with Restrictive Lung Disease (RD) still face physical and functional impairments a year later, needing targeted rehabilitation.
Area of Science:
- Pulmonology
- Rehabilitation Medicine
- Infectious Diseases
Background:
- COVID-19 hospitalization can result in persistent long-term health effects.
- This study investigates the progression of physical performance and functionality in patients with Normal lung Patterns (NP) versus Restrictive Lung Disease (RD) after COVID-19.
Purpose of the Study:
- To compare the recovery trajectories of physical performance and functionality in post-COVID-19 patients with and without Restrictive Lung Disease (RD).
- To assess the prevalence and persistence of Restrictive Lung Disease (RD) and associated functional impairments one year after hospital discharge.
Main Methods:
- Prospective cohort study design.
- Evaluation of 185 individuals at 1 and 12 months post-discharge, including lung function, physical performance, and functionality assessments.
- Comparison between patients with Normal lung Patterns (NP) and Restrictive Lung Disease (RD).
Main Results:
- At 12 months, 32% of participants still had Restrictive Lung Disease (RD).
- A significant portion of patients with RD (15%) experienced persistent functional impairments one year post-discharge.
- Both groups showed improvement in Sit-to-Stand repetitions, but RD patients had decreased physical performance at 1 month, with limited improvement by 12 months.
Conclusions:
- Nearly half (43%) of patients with Restrictive Lung Disease (RD) after COVID-19 still exhibited pulmonary alterations at one year.
- Persistent functional limitations were observed in 15% of RD patients one year after discharge.
- Long-term follow-up and specialized rehabilitation focusing on pulmonary function, physical performance, and functionality are crucial for post-COVID-19 recovery.
Background:
COVID-19 can lead to enduring long-term effects, particularly in severe cases requiring hospitalization. This study contrasts Normal lung Patterns (NP) with Restrictive lung Disease (RD) regarding the evolution of physical performance and functionality post-COVID-19 hospitalization.
Methods:
This is a prospective cohort study. Individuals post-COVID-19 were evaluated at 1- and 12-months post-discharge. Data collection included analysis of lung function, physical performance, functionality, and clinical data.
Results:
Of the 185 participants initially assessed, 62 attended the final evaluation. At 1 month post-discharge, 57 (92%) had been admitted to the ICU and 47 (76%) exhibited RD. After 12-months, RD decreased to 20 (32%). Both groups showed improved Sit-to-Stand repetitions (p = 0.002). A substantial percentage (28%) of participants with RD experienced functional impairments at one month, with a notable proportion maintaining these limitations after one year (15%).
Conclusions:
Almost half of individuals with RD (43%) still exhibited this pulmonary alteration after one year (RD 20/47). Additionally, RD participants demonstrated decreased physical performance at one month (15%), with only a fraction (5%) showing improvement after one year. Finally, these results pointed out the necessity of long-term follow-up regarding the recovery trajectory of post-COVID patients. Furthermore, there is a clear need to offer specific rehabilitation focusing on pulmonary, physical performance and functionality.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
