Physiotherapy management of Long-COVID: an evidence-based approach

Long-COVID is a heterogenous, episodic, and multisystemic condition which can result following infection with a novel pathogen, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Whilst a precise pathophysiological cause is unknown, several mechanisms are hypothesised, each with plausible scientific rationale. Most people experiencing persistent symptoms following COVID-19 infection recover, yet some experience severe and debilitating illness for years after infection. Strategies to manage the sequelae of Long-COVID can improve the lives of sufferers.

To describe the physiotherapy management of Long-COVID based on current evidence.

Those with 'invisible illness' (illness without outwardly visible signs), such as Long-COVID, often report stigmatisation and scepticism from healthcare systems. Validation of the experience of those with Long-COVID is therefore crucial to ensure patient-centred care. Thorough patient assessment is required to provide tailored management approaches given the diversity of Long-COVID presentations. Red flags that may contraindicate certain rehabilitation approaches (particularly exercise-based interventions) or that warrant further investigation should be considered. Assessments of fatigue, post-exertional malaise, respiratory symptoms, neurocognitive symptoms (i.e., brain fog), physical function, and orthostatic intolerance are strongly recommended. Management strategies may involve pacing and energy conservation techniques, pulmonary rehabilitation, inspiratory muscle training, dysfunctional breathing retraining, lifestyle and dietary strategies to manage orthostatic intolerance, and return-to-work planning.

Physiotherapists are well positioned to deliver individualised, patient-centred, and validating care based on best available evidence.
