Intradialytic Exercise Program Supported by Audiovisual Media Combined With Mindfulness

Exercise safety will be evaluated based on the total number of intradialysis group exercise sessions and their relationship with incidents or interruptions recorded in the progress sheets due to hypotension episodes.

Exercise safety will be evaluated based on the total number of intradialysis group exercise sessions and their relationship with incidents or interruptions recorded in the progress sheets due to symptoms of fatigue.

Exercise safety will be evaluated based on the total number of intradialysis group exercise sessions and their relationship with incidents or interruptions recorded in the progress sheets due to muscle cramps.

It will use a Jamar® Approved Hydraulic Hand Dynamometer. The participant will be seated in a chair with their back straight and the arm flexed at 90°. The test will be repeated three times for each hand (3-5 seconds), with rest periods between repetitions to avoid muscle fatigue. The cut-off points for loss of muscle strength will be set greater than or equal to 27 kg for men and greater than or equal to 16 kg for women, based on values defined by Mathiowetz et al. and included in the European clinical nutrition guidelines as a phenotypic criterion for disease-related malnutrition.

Lower limb muscle strength assessments using digital handheld dynamometry will be performed during hemodialysis, using the Lafayette Instrument Company MMT handheld dynamometer, model 01165 (Lafayette, IN, USA), with Newtons as the unit of measurement. The following lower extremity muscle groups will be evaluated: hip flexors and hip abductors. In accordance with the guidelines for lower limb strength assessment, tests will be conducted with subjects in a supine position and in the triple flexion position of the lower extremities.For hip flexion, the dynamometer will be positioned on the anterior aspect of the thigh, two centimeters above the upper border of the patella. The subject will perform a hip flexion movement while the evaluator, positioned at the subject's side, applies an opposing force of equal intensity. To evaluate the hip abductors, the dynamometer will be positioned on the lateral aspect of the thigh, two centimeters above the knee joint line.

To evaluate Anxiety and Depression using Hospital Anxiety and Depression Scale (HADS). The Hospital Anxiety and Depression Scale (HADS) is a widely used 14-item self-report questionnaire that screens for clinically significant anxiety and depression in both hospital patients with physical illnesses and the general population. It's split into two subscales (7 items each) for anxiety (HADS-A) and depression (HADS-D), using a 4-point Likert scale to assess current feelings, crucially avoiding somatic symptoms like fatigue to better detect mood issues in physically ill people. Scores range from 0 to 21 for anxiety and for depression, with higher scores indicating worst depression and anxiety

The HAP consist of 94 questions addressing different domains of daily activity and participation, with three possible answers for each item: 'still doing,' 'stopped doing,' or 'never did.' For each item, the participant will have to choose one of these responses. Based on each answer, two scores will be calculated: the Maximal Activity Score (MAS), which corresponds to the activity with the highest effort demand that the volunteer 'still performs'; and the Adjusted Activity Score (AAS), which will be calculated by subtracting the number of items the subject 'has stopped doing' below the MAS value from the MAS itself. The AAS will provide the value of activity that the subject has ceased to perform compared to what they were doing before.

To evaluate Perceived Stress taking Perceived Stress Scale (PSS).The Perceived Stress Scale (PSS) is a widely used self-report questionnaire designed to measure how stressful people find their lives, assessing the degree to which situations are appraised as unpredictable, uncontrollable, and overwhelming over the past month. The scale is rated from 0 to 56, higher score indicates higher stress.

To evaluate the perceptions from professionals and participants taking Self-Compassion Scale. The Self-Compassion Scale is a widely used psychological questionnaire, that measures how individuals treat themselves during times of suffering or failure, assessing core components like Self-Kindness vs. Self-Judgment, Common Humanity vs. Isolation, and Mindfulness vs. Over-identification. It helps gauge your capacity to offer yourself warmth, understanding, and connection, promoting better mental well-being, resilience, and personal growth by recognizing struggles as universal rather than isolating

Screening for sarcopenia risk will be performed using the SARC-F questionnaire, which consists of five self-reported questions based on the subjects' perception of their limitations regarding strength, walking ability, rising from a chair, climbing stairs, and their history and number of falls. Each item will be scored from 0 to 2, where 0 = no difficulty, 1 = some difficulty, and 2 = great difficulty, or if the subject uses devices or cannot perform the task without personal assistance. The total SARC-F score can range from 0 to 10, and subjects with a score ≥ 4 points will be considered at risk of sarcopenia, in accordance with the recommendations of the European consensus on sarcopenia
