The Hospital Anxiety and Depression Scale (HADS) is a fourteen-item scale scoring from 0 to 3 for each item. The first seven items relate to anxiety (HADS-A), and the remaining seven items relate to depression (HADS-D). The global scoring ranges from 0 to 42 with a cut-off point of 8/21 for anxiety and 8/21 for depression. The higher the score, the greater anxiety or depression symptoms.

The Perceived Stress Scale (PSS-10) is a ten-item scale that assesses the level of stress perceived by an individual in the last month. The questions are general in nature and fairly free of content specific to any subpopulation group. The items are designed to tap into how unpredictable, uncontrollable, and overloaded respondents find their lives to be. The scores range from 0 to 40, with higher scores indicating higher perceived stress. The Perceived Stress Scale will be administered at the beginning and after four weeks of treatment.

The Generalized Self-Efficacy Scale (GSES) is a ten-item psychometric scale that is designed to assess optimistic self-beliefs to cope with a variety of difficult demands in life. The scale measures the belief in one's competence to cope with a broad range of stressful or challenging demands. The score ranges from 10 to 40, with a higher score indicating a greater sense of self-efficacy. The Generalized Self-Efficacy Scale will be applied at the beginning and after four weeks of treatment.

The Barthel Index (BI) is an ordinal scale used to measure performance in activities of daily living (ADL). Each performance item is rated on this scale with a given number of points assigned to each level or ranking. It uses ten variables describing activities of daily living and mobility. Scores range from 0 to 100, with higher scores associated with a greater likelihood of being able to live at home with a degree of independence following discharge from the hospital. The the Barthel Index will be administered at the beginning and after four weeks of treatment.

The Rivermead Mobility Index (RMI) was developed from the Rivermead Motor Assessment Gross Function subscale as a means to quantify mobility disability. It is composed of 14 items representing different mobility tasks, ranging from turning over in bed to running. Each item is scored as 'unable' (0) or 'able' (1), leading to a maximum score of 14, which indicates full mobility. The Rivermead Mobility Index will be administered at the beginning and after four weeks of treatment.

Tinetti's Short Scale for fall risk assessment is a shortened version of Performance-Oriented Mobility Assessment (POMA). It is easily administered test that measures a patient's gait and balance. The test is scored on the patient's ability to perform following tasks: Change from sitting to standing, Immobilization in standing position for 5 seconds, Passing 3 meters, Turn of 180 degrees, Keeping a sitting position. Each task is rated in 3-point Likert scale. The scales rage from 0-15, with the higher scores indicate better functional mobility.

The Short Physical Performance Battery (SPPB) is a group of measures that combines the results of the gait speed, chair stand and balance tests. It provides a composite score ranging from 0 (worst performance) to 12 (best performance), offering a global assessment of physical functioning in older individuals. The SPPB will be administered at the beginning and after four weeks of treatment.

The Perception of Stress Questionnaire (PSQ) was created by Plopa and Makarowski. It is a 27-item scale scoring from 1 to 5 points for each item, where 21 items examine the level of stress in the areas of emotional tension, external stress and intrapsychic stress, and six items refer to the lie scale. The global scoring for the perception of stress ranges from 21 to 105, with a cut-off point of 60 for an elevated level of perceived stress. Higher scores indicate higher stress perception.
