PMID 41744352WHAT IT FOUND
People with long-COVID breathing symptoms improved in lower-limb strength, respiratory symptom burden, and quality of life over 12 months, but the primary measure of functional capacity showed no significant change.
Higher body mass index was linked to less improvement in fatigue.
Key findings
01The primary outcome, the 1-minute sit-to-stand test, showed no statistically significant improvement from baseline to 12 months.
02Secondary measures improved significantly: the 5-repetition sit-to-stand test time decreased, and the Chronic Obstructive Pulmonary Disease Assessment Test score decreased.
03Participants with a higher body mass index were less likely to reach the minimal clinically important difference for fatigue, lower-limb function, and functional capacity.

What it does not show
Only 58% of the original trial participants completed the follow-up, which introduces potential attrition bias. Because participants could cross over from the control group to the intervention group, it is impossible to determine if the telerehabilitation programme itself caused any of the observed changes. The study did not track whether participants received other treatments or interventions during the 12-month period. The sample size was small, limiting the ability to analyse categorical variables or detect smaller effects.
Declared interests
The study was funded by a Sydney Local Health District research grant. The authors declared no conflicts of interest, and the funder had no role in the study.
The easy way to misread this
Do not interpret the improvements in secondary outcomes as evidence that the telerehabilitation programme was effective. The primary outcome was null, and because the control group crossed over to receive the intervention, these changes likely reflect natural recovery over time rather than the specific effect of the 4-week programme.
