Individuals diagnosed with Long COVID, but without any severe mental disorders, will be recruited. The sample size is estimated to be around 54 participants per group. A psychologist and a physiotherapist will carry out the intervention between January and March 2025. Participants will receive specific training in psycho-education and physical rehabilitation consisting of 18 sessions, to be held twice a week. Data collection will start in January 2025 and will finish in October 2025. Data will be collected: at baseline, before the intervention (T0); after 9\u202fweeks, post-intervention (T1); and after 24\u202fweeks, follow-up (T2), and will assess quality of live, well-being, anxiety, depression resilience, fatigue, and physical activity. An intention-to-treat analysis will be performed and the effect size will be calculated using Cohen\u2019s d. All statistical analyses will be performed using R software version 4.2.2, with a 95% confidence level and a statistical significance level of <jats:italic>p<\/jats:italic>\u202f&amp;lt;\u202f0.05.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion\/conclusion<\/jats:title><jats:p>The results will be disseminated to individuals with Long COVID and their families throughout their primary health care center.
