Cognitive-sensorimotor effects on walking and balance after long COVID

Enhancing Veterans Long-COVID Care: A Cognitive-Sensorimotor Framework to Understand Gait and Balance Dysfunction

Observational VA Office of Research and Development · NCT06850350

This project will test whether thinking, vision, sensation, and muscle changes explain walking and balance problems in adults with long COVID.

What this trial studies

This is an observational study that compares adults with and without post-acute sequelae of SARS-CoV-2 infection (PASC) to understand contributors to gait and balance dysfunction. Researchers will measure cognition, vision, proprioception, muscle strength, and motor performance and will test gait and balance under cognitive dual-task conditions and in sensory-challenging environments. The protocol emphasizes real-world functional mobility tests designed to reveal how cognitive and sensorimotor deficits interact to impair walking and stability. Findings are intended to inform Veteran Health Administration diagnostic and standard-of-care protocols for restoring mobility and independence in affected patients.

Who should consider this trial

Good fit: Adults over 18 with a prior positive COVID test, whose COVID illness began more than three months ago, and who could walk 10 meters with or without assistance before their COVID illness are ideal candidates.

Not a fit: People with severe unrelated cardiovascular, pulmonary, neurologic, or musculoskeletal conditions, recent concussion or chronic pain syndromes that mimic long COVID, severe cognitive impairment preventing consent, or those who had severe COVID requiring ICU hospitalization are unlikely to benefit from this protocol.

Why it matters

Potential benefit: If successful, the work could lead to evidence-based diagnostic and treatment protocols that improve walking, balance, and independence for people with long COVID.

How similar studies have performed: Previous research in other populations has shown that cognitive and sensorimotor impairments can drive gait and balance problems, and emerging PASC studies suggest similar links, but application specifically to long COVID-related mobility dysfunction is still relatively new.
