Effect of telerehabilitation on post-COVID-19 individuals with long-term dyspnea: A randomized controlled study

Abstract

Objective

This study aimed to determine the effectiveness of telerehabilitation in managing ongoing dyspnea and associated issues following coronavirus disease 2019 (COVID-19), and observe changes over time.

Design

The study included 36 participants who previously had COVID-19 but continued to experience dyspnea (mean age, 42.44 ± 15.51 years). The participants were randomly allocated into three groups: telerehabilitation (TRG), home exercise (HEG), and control (CG). Dyspnea level, exercise capacity, muscle oxygenation, respiratory function, and fatigue were evaluated at baseline, at 6th, and at 12th weeks. Telerehabilitation was performed supervised and synchronously via video-calls.

Results

At the 6-week assessment, TRG showed significant improvements in dyspnea, fatigue (p < 0.001), exercise capacity (p = 0.001), and respiratory muscle strength (p < 0.001). By the 12th week, these gains were maintained, with no further changes from week 6. In HEG, dyspnea and fatigue improved at weeks 6 and 12 (p < 0.001), with no additional changes between these time points. In CG, only dyspnea improved at both assessments (p < 0.001); other parameters remained unchanged. TRG achieved greater benefits compared to CG in reducing dyspnea and fatigue at week 6 (p = 0.001 and p = 0.003, respectively), but no group differences were found at week 12 (p > 0.05). No changes in muscle oxygenation were observed in any groups or evaluation points (p > 0.05).

Conclusions

Telerehabilitation effectively improved and sustained dyspnea, fatigue, respiratory muscle strength, and exercise capacity in patients with post-COVID, while home-based exercises only reduced dyspnea and fatigue. Supervised and structured telerehabilitation may be a viable approach to managing post-COVID-19 symptoms.
