What this trial studies

This study evaluates the feasibility and safety of a combined water-based exercise and cognitive training program aimed at improving neurological symptoms in Veterans suffering from long COVID. The trial consists of two phases: an exercise phase involving individualized aquatic exercises and a cognitive training phase. It aims to recruit 50 Veterans aged 18 to 89 who have persistent neurological symptoms following COVID-19 infection. Participants will be randomized to either the intervention group or usual care, with the study assessing recruitment, retention, and the acceptability of the intervention.

Who should consider this trial

Good fit: Ideal candidates are Veterans aged 18 to 89 with persistent neurological symptoms following COVID-19 infection.

Not a fit: Patients with uncontrolled severe psychiatric disorders or significant neurological conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this program could significantly enhance recovery and quality of life for Veterans experiencing neurological symptoms of long COVID.

How similar studies have performed: Other studies have shown success with combined exercise and cognitive training approaches in cognitively impaired populations, suggesting potential for this novel application.
