THE HEADLINE TAKEAWAYBetter at 12 monthsQuality of life vs a single advice session, after weekly online group rehab
Online group rehab after hospital improved quality of life for a year.
585 adults with long COVID, at least three months after a COVID hospital stay, were randomly assigned to eight weeks of live online group exercise and psychological support sessions, or to a single online advice session (usual care). The group programme improved health-related quality of life more than usual care at three and 12 months.
A programme people join from home, in live online groups, helped hospital survivors with long COVID feel better for a full year, showing that rehab can reach people at scale without a clinic visit. Randomized trial in England and Wales that enrolled only people previously hospitalized with COVID; participants knew which group they were in and rated their own quality of life.

Only 29% felt fully recovered a year after a COVID hospital stay.
29% felt fully recoveredHospital survivors feeling fully recovered 1 year after discharge (25.5% at 5 months)
Among UK adults hospitalized with COVID, 28.9% said they felt fully recovered 1 year after discharge, about the same as the 25.5% at 5 months. Women, people with obesity and those who had needed invasive mechanical ventilation (a breathing machine) were less likely to report full recovery at 1 year.
Most hospital survivors were still not back to normal a year on, with little change after the first months, so long-term follow-up and support matter, especially for the groups least likely to recover. Observational UK cohort of people discharged March 2020 to April 2021; only 807 of 2,320 attended both the 5-month and 1-year visits, and recovery was self-rated.

The PHOSP-COVID study followed 2,320 adults discharged from UK hospitals after COVID, checking them at about 5 months and 1 year.
From the study: “The proportion of patients reporting full recovery was unchanged between 5 months (501 [25·5%] of 1965) and 1 year (232 [28·9%] of 804).”

One-to-one rehab helped people with long COVID brain fog reach daily goals.
66% vs 15%Made a big (4+ point) gain on personal goals at 3 months: rehab vs usual care
Adults with long COVID and measured thinking problems were randomly assigned to weekly one-to-one video sessions of goal-focused cognitive rehabilitation, or to usual care. A big gain (4 or more points) on their own everyday goals came in 65.8% vs 15.0% at 3 months, and the benefit lasted to 6 months. Fatigue, post-exertional malaise, anxiety, depression and sleep did not differ.
Brain fog has had no proven treatment. Here, coaching people to use practical strategies on tasks they chose helped them get those tasks done, even though fatigue and most thinking-test scores stayed the same. Small single-blind trial of 78 mostly White adults aged 30 to 60 in England; goals were self-rated, the responder figures were exploratory, and follow-up thinned by 6 months.
See the evidence
A randomized trial at 3 sites in England, run 2023 to 2024, in 78 adults with long COVID and objectively measured thinking problems.
From the study: “Using a more stringent threshold of 4 or more points in improvement, 25 participants in the CR group (65.8%) met this criterion at 3 months compared with 6 participants in the TAU group (15.0%).”

Three remote brain-fog treatments failed to beat puzzles or sham stimulation.
No better than puzzlesRemote brain-fog treatments vs online puzzles or sham stimulation
In 328 US adults with long COVID brain fog, 10 weeks of adaptive brain-training games (BrainHQ) or structured cognitive rehabilitation plus BrainHQ did no better on self-rated everyday thinking (the ECog2 scale) than unstructured online puzzles, and real brain stimulation did no better than sham. All 5 groups, puzzles included, improved somewhat over time.
This large US trial could not show that brain-training, structured rehab or brain stimulation add anything for brain fog beyond simple puzzle games, though people in every group reported some improvement. Phase 2 trial with a self-reported main outcome, run August 2023 to June 2024; people joined on self-rated thinking complaints, without needing low scores on objective tests.

1 in 4 US adults with long COVID report significant activity limits.
About 1 in 4 limited26.4% of US adults with long COVID had significant activity limits, June 2023
In a national US survey, 26.4% of adults with long COVID in June 2023 said their symptoms significantly reduced their ability to carry out day-to-day activities compared with before COVID. That share did not change over time, even as long COVID fell from 7.5% to 6.0% of all US adults over the study year.
Fewer Americans have long COVID than a year earlier, but among those who do, the share whose daily lives are seriously disrupted has not shrunk, a steady need for rehab, workplace and care support. Repeated cross-sectional online Census survey with self-reported long COVID and limits, so it tracks the population rather than following the same people over time.

Muscle damage in long COVID worsened a day after a hard workout.
Muscle worse one day onLeg-muscle biopsies before and one day after a maximal cycling test in long COVID
Leg-muscle biopsies were taken from people with long COVID and post-exertional malaise before and one day after a maximal cycling test, and compared with people fully recovered from mild COVID. Patients had more easily tired muscle fibers and weaker mitochondria (cells' power plants), and muscle damage (myopathy) and amyloid-containing deposits worsened after the exertion.
This points to a physical basis for post-exertional malaise: hard effort was followed by measurable muscle injury, which helps explain why long COVID rehab paces effort instead of pushing through. Small case-control study (25 patients, 21 recovered controls) of people selected for post-exertional malaise; the authors note some muscle differences could have been present before long COVID.

Workouts raised long COVID fatigue no more than in healthy peers.
No extra fatigueChange after single workouts: long COVID patients with PEM vs matched healthy adults
Adults with long COVID and post-exertional malaise (symptoms that flare after effort) and matched healthy adults each did an interval, a steady and a strength workout in random order. Fatigue did not worsen more than in the healthy group, but muscle pain rose more after intervals and concentration trouble after steady exercise. 62% of patients had signs of muscle disease (myopathy).
It challenges the idea that every bout of exercise is off-limits with post-exertional malaise, yet pain and concentration still flared, which is why the authors call only for cautious exercise. Small randomized crossover trial in Sweden of 31 patients and 31 healthy controls without other diseases; each did only one closely monitored session of each exercise type.

88% back at their jobPreviously employed hospital survivors back at their original work at 12 months
Among adults discharged from one Wuhan hospital early in the pandemic, 88% of those employed before COVID-19 had returned to their original work at 12 months. Symptoms eased: 49% still had at least one lingering symptom, down from 68% at 6 months. Not everything improved: breathlessness rose slightly, from 26% to 30%.
Even after a hospital stay for COVID, most working people got back to their own jobs within a year, though some did not and breathlessness lingered for others. Observational cohort from one Wuhan, China, hospital of people discharged January to May 2020; work status was self-reported at the 12-month visit.

Exercise may ease fatigue and breathlessness; certainty varies
Exercise training improved fatigue and breathlessness more than usual care in pooled randomized trials of people with Long COVID.
Evidence certainty ranged from moderate to very low, with differing programs and populations. Symptom worsening after exertion was not consistently monitored or reported, and long-term follow-up was limited.

Acupressure and Qigong showed no clear physical-function benefit
Adding self-applied acupressure and online Qigong did not show a clear physical-function advantage, despite slightly greater improvement in fatigue as a secondary outcome.
This randomized trial studied post-infectious fatigue with impaired physical function at 8 weeks, versus written self-care advice and routine care alone. Both groups received that advice and care. The physical-function interval includes no difference.

Tele-rehabilitation eased symptoms without a clear mobility gain
Adding tele-rehabilitation to usual care improved pain, health status, fatigue and breathlessness more than usual care alone, but did not establish a mobility advantage.
The trial studied people with Long COVID in an 8-week program. The mobility interval includes no difference; symptom improvements and mobility are different measured outcomes.
High adherence did not mean everyone could advance exercises
The tele-rehabilitation program reported high adherence, yet 39% of intervention participants were unable to progress their exercises.
This describes feasibility during the 8-week program for people with Long COVID, rather than a comparison with usual care or a measure of symptom benefit.
