This systematic review of randomized controlled trials assessed supervised, face-to-face non-pharmacological interventions in adults with WHO-defined post-COVID-19 condition. It included 27 trials involving 1,998 participants and used narrative synthesis because of clinical and methodological heterogeneity. Supervised cardiopulmonary rehabilitation and multimodal exercise consistently improved cardiorespiratory fitness and walking capacity, while cognitive-behavioural therapy and lifestyle adjustments reduced fatigue and subjective concentration complaints. Evidence for neuromodulation, complementary approaches, and oxygen therapies was mixed, often showing no advantage over placebo.
Key findings
- The review included 27 randomized trials with 1,998 participants.
- Supervised cardiopulmonary rehabilitation and multimodal exercise consistently improved cardiorespiratory fitness and walking capacity.
- Cognitive-behavioural therapy and lifestyle adjustments reduced fatigue and subjective concentration complaints.
- Only 18.5% of trials were judged at low risk of bias.
Why it matters
Post-COVID-19 condition can involve persistent functional and symptomatic difficulties. The review suggests that supervised rehabilitation and psychological approaches may help address these outcomes, while findings for several other interventions remain uncertain. The evidence also highlights the need to interpret apparent benefits cautiously because most included trials had methodological limitations.
What to keep in mind
Only 18.5% of trials had low risk of bias; limitations included small samples, unblinding, and short follow-up. Clinical and methodological heterogeneity required narrative rather than pooled synthesis.
