Although most infected people survive the infection, many have persistent sequelae or symptoms, which cause disability or decreased quality of life. The World Health Organization has called on countries to prioritize the rehabilitation of the consequences of COVID-19 in both the medium and long term, as this chronicity is expected to impact the health public and the economy in the coming years.
RehabCOVID (also referred to as RehabNautilus) is born from the need to provide solutions to persistent cognitive impairment symptoms of people who have suffered from COVID-19. Thus, we will offer people with long COVID that accomplish inclusion/exclusion criteria to participate in a randomized clinical trial to evaluate the effectiveness of cognitive stimulation therapy combined with physical exercise and mindfulness. The current project is a single-blind randomized control study, where we will compare two combined interventions with a control group that will encompass different functional, structural, and biochemical changes and interactions in the brain. We will study the effects that this combined intervention produces in the brain. We expect to gain more insight into the specific neuroplasticity mechanisms of cognitive persistent COVID symptoms.

Specifically, we aim to:
We hypothesize that we will find recovery in our three groups, although it will be enhanced in the two experimental groups (those that combine cognitive training with physical activity and mindfulness) compared to our control group.

It is a unifactorial questionnaire and consists of 30 items. The total score results from the sum of the scores in each item, from 1 to 30. The MFE can assess the current situation of the patients and their evolution long-term or changes due to treatment. Scores <8 represent an optimal memory function. Lower scores indicate better outcomes. | Before the intervention and 12 weeks later |
| Differences between groups in scores of depression |
Depression is measured with the Patient Health Questionnaire-9 (PHQ-9) which scores each of the 9 DSM-IV criteria as "not at all" (0 points) to "nearly every day" (3 points). Higher scores mean a worse outcome. |
| Before the intervention and 12 weeks later |
| Differences between groups in scores of Mindfulness levels | Mindfulness levels are measured with The Mindful Attention Awareness Scale (MAAS) assesses an individual's level of mindfulness, including attention, awareness, and non-judgment. The 15-item self-report questionnaire uses a 6-point Likert scale to measure an individual's general tendency to be aware of and attentive to their current experience. Scores on the MAAS range from 15 to 90, with higher scores indicating greater levels of mindfulness. A higher score suggests better outcome. | Before the intervention and 12 weeks later |
| Differences between groups in scores of Fatigue | Fatigue is measured with the Chalder Fatigue Scale, an 11-item questionnaire measuring the severity of physical and mental fatigue on two separate subscales. Seven items represent physical fatigue (items 1-7) and 4 represent mental fatigue (items 8-11). Each item " less than usual" (0) to " much more than usual" (3). The ratings of items are added together to calculate the total score (range=0-33). High scores represent high levels of fatigue. | Before the intervention and 12 weeks later |
| Differences between groups in scores of psychological flexibility | Psychological flexibility is measured with the Acceptance and Action Questionnaire, a 7-point Likert scale, ranging from 1 ("never true") to 7 ("always true"), indicating how frequently they experience the described behavior or feeling in their daily lives. The scale has 9 items and the total score ranges from 9 to 63, with higher scores indicating greater levels of psychological flexibility (better outcome). | Before the intervention and 12 weeks later |
| Differences between groups in Functionality | Functionality is measured with a 12-item World Health Organization Disability Assessment Schedule-II (WHODAS-II). Patients are asked to state the level of difficulty experienced, considering how they usually do the activity. The scale scores each item as "none" (1) to "cannot do" (5). The total score is calculated with an SPSS syntax, and the range varies from 0 to 100, with higher scores reflecting more significant disability. | Before the intervention and 12 weeks later |
| Differences between groups in scores of Sleep Quality | Sleep Quality is measured with The Pittsburgh Sleep Quality Index (PSQI). This test presents 24 items, although only 19 are taken into account for the correction. This test is divided into 7 dimensions, namely, sleep quality, sleep onset latency, sleep duration, sleep efficiency, sleep disturbances, hypnotic drugs, and daytime dysfunction. Higher scores indicate worse sleep quality. | Before the intervention and 12 weeks later |
| Differences between groups in scores of Quality of Life | Quality of Life is measured with EuroQol a self-completion questionnaire, which consists of five questions: covering mobility, hygiene, activities, pain, and anxiety. The descriptive system divides each of the 5 dimensions into three levels of response: the absence of a problem, some problem, and extreme problem. Lower scores indicate better outcomes. In addition, the questionnaire has a plus scale where the participants rated their health state on a scale of 0-100. In this scale, higher scores indicate better outcome. | Before the intervention and 12 weeks later |
| Differences between groups in scores of performed physical activity | Performed physical activity is measured with The International Physical Activity Questionnaire (IPAQ) is a questionnaire composed of 7 questionsin order to assessthe frequency, duration, and intensity (vigorous or moderate) of the performed physical activity, walking, and sitting time during a business day for the last 7 days. Later, from the minutes obtained from the participant's answers, the METS (metabolic equivalent tasks) conversion is performed, allowing a classification, depending on the energy consumption obtained for each activity, into three categories (low, medium, high). Higher score indicate better outcome. | Before the intervention and 12 weeks later |
