-
Immunoadsorption blood filter for autoimmune long COVID
We will test a blood-filter treatment called immunoadsorption in people with long COVID who have specific autoantibodies to see if their fatigue and daily functioning get better.
-
Kneipp cold-water hydrotherapy for people with Long COVID
This randomized trial will test whether regular Kneipp cold-water hydrotherapy can improve quality of life for people with Post‑COVID Syndrome.
-
Magnetic resonance and rapid brain stimulation for Long COVID cognitive and mood symptoms
This trial will test whether an accelerated outpatient magnetic brain stimulation (iTBS) can help reduce brain fog, depression, and anxiety in adults with Long COVID.
-
Functional and cognitive rehabilitation versus informational support for adults with Long COVID and chronic conditions
This trial will try a combined physical and cognitive rehab program versus weekly evidence-based messages to see if adults with Long COVID and pre-existing hypertension or diabetes walk farther, think clearer, and feel better overall.
