Abstract:
Purpose: Postural sway and physical capacity had not previously been compared between people with long COVID and people with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). Therefore, this study determined postural sway and physical capacity in people with long COVID (∼16 month illness duration; n=21) and ME/CFS (∼16 year illness duration; n=20), versus age-matched healthy controls (n=20).
Methods: Postural sway was during a 30 s static stand test. Physical capacity was determined using the timed up and go test and five times sit to stand test. Throughout, participants wore isoinertial measurement units.
Results: Postural sway was worse (i.e. greater) in people with long COVID and ME/CFS than controls, but not different between long COVID and ME/CFS. Performance of the timed up and go test and five times sit to stand test were worse in long COVID and ME/CFS than controls, but not different between long COVID and ME/CFS. 87% and 13% of long COVID and ME/CFS participants exceeded the threshold for muscle weakness in the five times sit to stand test and timed up and go test, respectively.
Conclusions: These data suggest that both people with long COVID and people with ME/CFS have similarly impaired balance and physical capacity. Therefore, there is an urgent need for interventions to target postural sway and physical capacity in people with ME/CFS, and given the current pandemic, people with long COVID.
