The intervention include 12 face-to-face group sessions of 45 minutes each, twice a week for 6 weeks. The intervention include OEP-based techniques only. At the end of the sessions, participants will be instructed to perform nine exercises independently at home, at a minimum of twice per week for six months.

Objective balance assessment will perform using the Five Times Sit to Stand (5STS) test. The time taken by participants while getting up from a seated position in a chair and standing up and sitting down five times, was measured. Norm scores for ages 70 to 79 and 80 to 89 are 12.6 seconds and 14.8 seconds, respectively.

Fear of Falling assessment will perform using the FOF single item question (FOF SIQ) which is a single self-report question: "Are you afraid of falling?". The question is rated on a Likert-type scale ranging from 1 (no, not afraid) to 4 (yes, indeed afraid).

Falls Efficacy assessment will perform using the Short Falls Efficacy Scale-International (Short FES-I), which is a self-report questionnaire that includes seven items rated on a Likert-type scale ranging from 1 (not at all concerned) to 4 (extremely concerned). The overall score of the questionnaire is the sum of its items, and the score range is be-tween 7 and 28. A lower score indicates better self-efficacy related to falls.

Depression Assessment Questionnaire assessment will perform using the Patient Health Questionnaire (PHQ-9), which is a self-report questionnaire used to assess the presence and severity of depression. It consists of 9 items that list major depressive symptoms, based on the Diagnostic and Statistical Manual of Mental Disorders, and are rated on a 4-point scale ranging from 0 (not at all) to 3 (almost every day). The overall score of the questionnaire is calculated by summing the scores of all items and ranges from 0 to 27, with a higher score indicating a higher level of distress and depression. The researchers propose the following levels of depression: score 0 to 5 indicates absence of depression; score 6 to 9 indicates subsymptomatic/low depression; score 10 to 14 indicates moderate depression; score 15 to 19 indicates moderate-severe depression; and score 20 to 27 indicates severe depression.

Self-perceived health status assessment will perform using the 12-item Short Form Health Survey (SF-12), which is a self-report questionnaire that includes 12 items that are summarized as two scores: the Physical Component Summary (PCS-12), which refers to the physical aspect of health status, and the Mental Component Summary (MCS-12), which refers to the mental aspect of health status. Four items are rated on a dichotomous yes/no scale, while the remaining items are rated on a Likert-type scale with response options ranging from 3 to 6. The average score in each component is 50, and the standard deviation is 10. The overall scores range from 0 to 100. A higher score indicates a better perception of health status and quality of life.

Weekly telephone follow-up will be conducted for a month after the end of the intervention to assess persistence in the home practice program, including the number of days of practice per week and the number of exercises performed. In addition, home exercise adherence assessment will performed using the Exercise Adherence Rating Scale (EARS), which assesses an individual's adherence to performing exercises which were instructed by healthcare professional to perform at home. This self-report questionnaire includes six items rated on a Likert-type scale ranging from 0 (Completely agree) to 4 (Completely disagree). In one item, the phrase "my healthcare professional" was replaced with "the group instructor" to align with the study. The overall score of the questionnaire is the sum of its items, and the score range is between 0 and 24. A higher score indicating a higher level of adherence to performing exercises at home.

The SVS is a self-report questionnaire used to assess subjective feelings of aliveness during the intervention sessions. It consists of 7 items rated on a Likert scale ranging from 1 (strongly disagree) to 7 (strongly agree) in reference to the participant's feelings during the sessions. The overall score of the questionnaire is calculated as the average of all items, and the score range is from 1 to 7, where a higher score indicates a higher level of perceived vitality.

A self-report question to assess the patient's expectations from the intervention will be administered prior to the start of the intervention program (pre-test). The question is: 'To what extent do you believe that the sessions will help you feel better?' The response options are rated on a 3-point scale: 1 (not at all), 2 (to a moderate extent), or 3 (to a very large extent). weekly during the intervention period (mid-test), and after completing the intervention program (post-test), the patient will rate whether the intervention met their expectations on a 3-point scale: 1 (lower than expected), 2 (as expected), or 3 (higher than expected).

Participants will undergo an open questions, telephone-based to evaluate their personal experience during the intervention period and afterwards, as part of an assessment of the quality of the intervention program. During the intervention period, participants will be asked two questions: "What was meaningful to you in the sessions this week?" and "What was significant to you in guiding the sessions this week?". After the intervention period, participants will be asked three questions: "What was most meaningful to you in the sessions?", "How did the sessions affect you physically?" and "How did the sessions affect you emotionally?". Additionally, one month after the end of the intervention, each participant will be asked: "What do you remember most from the meetings? And why?".
