Duration of 45 minutes. A complete dorsal and ventral body massage will be performed, with superficial maneuvers at a slow pace of traditional massage.

The person will be instructed to stay for 45 minutes during which he/she will receive different electrotherapy techniques with the devices disconnected, a mobile device that simulates a beep will be placed so that the patient believes that the device is connected.

Assessed with the EBS-8 subjective well-being scale, which assesses the two components of well-being: life satisfaction and positive affect and with a visual analog scale 0-10.

The Mood Rating Scale (EVEA) will be used, which evaluates mood states with a range from 0 to 10 and as a time reference "right now". It consists of 4 subscales: sadness-depression, anxiety, anger-hostility and joy.

Assessed by the "Trail Marking Test", which assesses t used to evaluate attention, flexibility of thought and visuospatial ability. It consists of two parts. In both cases, the subject will need a pencil and the evaluator a stopwatch, counting the execution time for each of the parts as soon as the pertinent indications have been given. In part A, the participant will join in ascending order all the numbers from 1 to 25 arranged on a sheet of paper. In exercise B, the process will be repeated, but alternating letters and numbers in alphanumeric order. In both cases, the time spent will be quantified.

Assessed through a distress thermometer, a likert scale in which 0 corresponds to the option "No distress" and 10 with "Extreme distress"

The "sit and reach" test will be performed, for the evaluation of flexibility in which the subject, who is seated on the edge of a chair (placed against a wall for safety reasons), and one foot resting on the sleep, will extend the other leg forward with the knee straight, the heel resting on the sleep and the ankle at 90º, placing one hand on top of the other with the tips of the central fingers equal. The participant will be instructed to inhale and, on exhalation, extend the hand forward toward the toes by bending at the hip. The distance will be measured between the fingertips and toes so that, if the fingertips touch the toes, the score is 0, if they do not touch, the resulting distance in cm will be negative and, if they overlap, we are talking about a distance in cm positive.

With the sit-to-stand test 30 seconds, which measures how many times a person can transition from sitting in a chair to standing and back to sitting within 30 seconds.

After completing the 30-second sit-to-stand test, participants rate their perceived level of fatigue using the Borg CR10 scale. This scale ranges from 0 (no fatigue at all) to 10 (extreme fatigue) and provides a subjective measure of exertion following the activity.

Salivary samples will be collected first thing in the morning, using a timer and ensuring the entire sample is collected within three minutes. Without ingestion of caffeine and/or stimulant substances 12 hours before, as well as with complete oral hygiene (dental brushing and use of mouthwash, preferably) the night before.

Salivary samples (400µL) will be collected in specific collection kits for 2ml salivary sample and cryovials (Salimetrics, LLC, Carlsbad, United States), to proceed to their subsequent immediate freezing at -80ºC until the pertinent analysis of cortisol through ELISA is performed.

Measured with the patient seated after at least 10 minutes of rest using a sphygmomanometer.

Measured with the patient seated after at least 10 minutes of rest using a sphygmomanometer.

Measured with the patient seated after at least 10 minutes of rest using a sphygmomanometer

Measured using a pulse oximeter placed on the fingertip, ensuring the patient is seated and at rest for at least 10 minutes prior to measurement.

Assessed through a yes/no questionnaire to determine prior experiences, followed by an open-ended question to record the type of modality if applicable

The Perceived Stress Scale (PSS-10) is a self-assessment tool used to measure the level of perceived stress in individuals in his or her life during the past month. The scale consists of 10 questions that explore different aspects of perceived stress, such as how often individuals feel that their life is out of control, feel nervousness, or are unable to cope with their responsibilities. The total score is obtained by summing the item responses. Some questions are positively worded and are reverse scored.

The Connor-Davidson Resilience Scale (CD-RISC) is a self-assessment tool that measures a person's ability to overcome adversity. It is composed of 25 items that are answered on a 5-point Likert scale, ranging from 0 (never) to 4 (almost always). Total scores can range from 0 to 100, with higher scores indicating greater resilience.

Will be collected using an open-ended questionnaire where participants will provide their exact age

Will be collected using an open-ended questionnaire where participants will provide their Place of Residence

Will be assessed through a multiple-choice questionnaire, allowing participants to select the most appropriate response for their situation.

Will be assessed through a multiple-choice questionnaire, allowing participants to select the most appropriate response for their situation.

Will be assessed through a multiple-choice questionnaire, allowing participants to select the most appropriate response for their situation.

Will be collected using a range-based question, where participants will indicate the income bracket that best reflects their household's monthly or annual income

Measured using a calibrated stadiometer with participants standing upright and barefoot

Measured using digital scale, with participants standing barefoot, and in light clothing.

Measured using a non-stretchable tape, ensuring standard anatomical landmarks are used: between last ribs and iliac creast, at the narrowest point

Measured using a non-stretchable tape, ensuring standard anatomical landmarks are used: above the greater trochanter

Calculated by dividing waist circumference by hip circumference

These behaviors will be assessed through a structured questionnaire, including frequency and quantity of use over the past months.

Measured using questions about time spent sitting or reclining during typical weekdays and weekends, excluding sleep hours

Physical activity will be assessed using the International Physical Activity Questionnaire (IPAQ), which captures the type, frequency, and duration of physical activities performed weekly, categorized into light, moderate, and vigorous intensity levels.
