Multimodal Long Covid19

Fatigue Assessment Scale (FAS) - The FAS questionnaire consists of 10 questions and its objective is to investigate the presence of fatigue in a patient, its response is by means of a likert-type scale in which higher scores imply a greater degree of fatigue, its measurement parameters are based on two categories whose maximum score is 50 points. FAS scores 10 - 21: no fatigue (normal) FAS scores 22 - 50: substantial fatigue

Test Time Up and GO - Its objective is to evaluate the dynamic balance, as well as the functional capacity and mobility of a person to perform activities of daily living. establishing mobility parameters in such a way that the more time used, the lower the mobility capacity. Less than 10 seconds: independent mobility. Between 10 and 20 seconds: mostly independent mobility. More than 20 seconds: reduced mobility.

Six-minute walk test - The 6-minute walk test is a submaximal exercise test used to assess aerobic capacity and endurance. The distance walked for a time of 6 minutes is used as a result to compare changes in performance capacity. The more meters the patient runs, the better his cardiorespiratory functional capacity. If a patient reaches 304 meters in the 6 minutes, he achieves cardiorespiratory functional independence category, if he achieves less than that distance, a decrease in cardiorespiratory functional capacity is established.

Beck Anxiety Scale - consists of a 21-item self-administered instrument in which the patient is asked to report the extent to which he or she has been affected by each of the 21 symptoms described in the scale. Each item has four possible response options: not at all, mildly, moderately and severely. Values from 0 to 3 are assigned to each of the items. The values for each item are summed to obtain a total score that can range from 0 to 63 points. A total between 0 and 7 points is interpreted as a minimum level of anxiety, between 8 to 15 points corresponds to a mild level of anxiety, from 16 to 25 points is moderate anxiety and from 26 to 63 points is considered severe anxiety.

Beck Depression Scale - It consists of a 21-item self-administered instrument designed to assess the severity of depressive symptomatology in adults. In each of the items, the person has to choose, from a set of four alternatives ordered from least to most severe, the statement that best describes his or her state during the last two weeks, including the day on which he or she completes the instrument. As for the correction, each item is valued from 0 to 3 points depending on the alternative chosen and, after directly adding the score of each item, a total score can be obtained that varies from 0 to 63 points; thus, its categories range from minimal depression (0-13); mild depression (14-19), moderate depression (20-28) and severe depression (29-63).

Montreal Cognitive Assessment - This instrument examines cognitive dysfunctions associated with attention, concentration, executive functions (including abstraction capacity), memory, language, visuoconstructive abilities, calculation and orientation. The maximum score is 30 points and its score is proportional to the level of cognitive functionality, so that the lower the score, the greater the cognitive impairment. A score equal to or higher than 26 points is considered normal; a score lower than 10 points implies incipient cognitive impairment; from 20 to 23 points: Mild cognitive impairment and if the patient achieves 26 points or more, there is no alteration of cognitive functions.

Barthel Index - It is a test that provides ranges with scores between 0 and 100, regarding the level of functional behavioral independence for a patient. The closer a subject's score is to 0, the more dependent he/she is; the closer to 100, the more independent he/she is. Based on the results obtained in the evaluation with the Barthel Index or Scale, the classification will be: Total Dependent (less than 20 points), Severe Dependence (20 - 35 points), Moderate Dependence (40 - 55 points), Mild Dependence (greater than or equal to 60 points) and Independence (100 points).

Short Form 12 Health Survey - Health related quality of life questionnaire. The response options of the SF-12 form Likert-type scales that evaluate intensity or frequency of quality of life indicators associated with health. The number of response options ranges from three to six, depending on the item, and each question is given a value that is then transformed into a scale from 0 to 100. The scores have a mean of 50 with a standard deviation of 10, so that values above 50 indicate better health-related quality of life or below 50 indicate a worse state of health-related quality of life.

Body composition analyzer - This instrument establishes the level of body fat in people, establishing frames of reference with scores differentiated by sex, classifying as low range in men when their score is less than 9.9%, and women less than 17.9%; normal level: Men between 10 to 19.9%, women between 18 to 27.9%; High: Men between 20 to 58%, women between 28.0 to 58%. Therefore, the higher the percentage, the higher the degree of health risks associated with overweight.
