Rehab programs can improve quality of life for patients struggling with long COVID: research
CBC
People struggling with long COVID tend to be able to walk longer and farther when they do individualized exercises, a new review suggests.
When symptoms such as fatigue, headache and shortness of breath last for at least two months, with no other explanation, they meet part of the definition of what the World Health Organization now calls post COVID-19 condition.
Part of the challenge is that symptoms can fluctuate unpredictably. Previous research suggests that the wide range of symptoms and their severity, as well as different time frames, make it harder to study long COVID in a systematic way to guide treatment.
This new research helps fill in that picture on how exercise helps people walk further and faster, given that those with long COVID commonly say they have a hard time handling long or strenuous walks, which in turn hampers their quality of life.
To that end, researchers pooled findings from 14 randomized clinical trials — the gold standard to evaluate medical studies and reduce bias. That way, doctors will have more information when choosing treatments like exercise for adults with long COVID.
"We found evidence suggesting that rehabilitation programs can be beneficial in improving walking capacity and quality of life," said Pavlos Bobos, the study's lead author and an assistant professor in the school of physical therapy at Western University in London, Ont.
The meta-analysis and systematic review was published in this week's issue of JAMA Network Open.
Dr. Mark Bayley, medical director at the Toronto Rehabilitation Institute, heads the University Health Network's program to help patients with long COVID-19 recover from fatigue.
Exercise is a primary treatment or rehabilitation for patients with long COVID, Bayley said. The treatment includes respiratory strengthening to retrain the muscles in the chest to facilitate taking a deeper breath.
People with long COVID may have adopted a breathing pattern that doesn't work as well as normal, and that's where breathing exercises come in.
"Some of it is really allowing the person to recognize that, yes, they're short of breath, but yes, they can maintain their comfort level despite the fact that maybe they're exerting themselves," Bayley said.
People then feel less nervous and short of breath, which allows them to participate in more vigorous activity such as jogging or walking longer.
In rehabilitation medicine, aerobic and strength training is also offered.
Bobos cautioned there's still some uncertainty about the potential for problems like post-exertional malaise. That happens when the person exercises, and then later that day or the following day, they feel unwell and symptoms rebound. The issue can also occur with myalgic encephalomyelitis, formerly chronic fatigue syndrome.
