Plain English Summary

Background and study aims
People recovering from COVID-19 can feel weak, breathless and tired. Some people are also worried and frightened. For most people, these problems will get better on their own, but for some people, they may continue for a long time after leaving hospital. A rehabilitation programme may help. For people who are still struggling months after being ill with COVID-19, the aim of this study is to find out which of two treatments is better for helping people recover: a single online session of exercise advice and support or an 8-week online exercise and support programme

Who can participate?
People who have been treated in hospital for COVID-19 who were discharged more than 3 months ago and still have health problems due to COVID-19

What does the study involve?
After a questionnaire has been completed, participants will be assigned by chance (randomised) to one of the two treatments. Participants assigned to a single online session of exercise advice and support will have a 30-minute call with a REGAIN exercise specialist during which they will be given information on how to safely increase activity and exercise at home. They will also be directed to websites where more information and support can be found and will be able to ask questions about recovery from COVID-19.
Participants assigned to an 8-week online exercise and support programme will have a 60-minute call with a REGAIN exercise specialist during which they will be given an activity and exercise plan to follow at home. Participants will also be directed to websites where more information and support can be found and will be able to ask questions about recovery from COVID-19. They will also join a live online exercise (1 hour per week) and support (1 hour per week) group for 8 weeks, and will be able to access on-demand physical activity and exercise sessions as required.

What are the possible benefits and risks of participating?
Although this study may not offer any direct benefit, the findings may help people recovering from COVID-19 in the future. The researchers do not anticipate any serious risk to participants. There is always a very small chance that exercise can make people feel unwell. Exercise may cause tiredness, breathlessness and sore muscles, but this should get a bit easier over time. All exercise will be advised and monitored by specialist staff. Sometimes people can find the support sessions upsetting. Fully trained specialist staff will provide appropriate support and assistance if needed.

Patient information sheet


COVID-19 (SARS-CoV-2 infection)


A multi-centre RCT testing the clinical and cost-effectiveness of an intensive, online, supervised, group, home-based rehabilitation programme that supports long-term physical and mental health recovery (REGAIN) vs. best-practice usual care for people discharged from hospital (>3/12) after COVID-19 infection.

Patients will be identified via two routes:

1. Participant Identification Centres
Clinical care teams at UHCW NHS Trust and each PIC site (NHS hospital trust) will screen hospital discharge data and identify potential participants for contact by mail. The sites will send potential participants an infographic flyer and invitation letter which will direct potential participants to the study website to find out more information and to register their interest.

2. Self Referral
The study will be promoted through local/national media/social media, relevant charities and on the study website. People suffering from ongoing COVID-19-related symptoms following hospital discharge will be able to self-refer and to register their interest via the study website.

Further to baseline assessment, a total of 535 participants will be randomised to the REGAIN intervention or best practice usual care.

The REGAIN Intervention: Eight-week, online, supervised, home-based, exercise rehabilitation programme with behavioural, motivational and mental health support.

Best-practice usual care consisting of a single online session of advice and support.

Outcomes will be assessed at baseline pre-randomisation, 3, 6 and 12 months (post-randomisation). The primary outcome will be HRQoL measured using the PROMIS® 29+2 Profile v2.1 (PROPr) at 3 months post-randomisation. Data will be collected directly from trial participants using online data collection.
