Thoracic mobility exercises Group: Conventional physiotherapy exercises were given to individuals participating in the Thoracic mobility exercises group. Conventional physiotherapy exercises included warm-up, stretching, strengthening, posture and breathing exercises integrated between them. These exercises were performed in 30-40 minute sessions, 3 days a week and for 6 weeks. Thoracic mobility exercises were applied to individuals participating in the study group in addition to conventional physical therapy exercises.

Beck Balance Scale is a scale that evaluates balance in the elderly, where some performance tests are applied to evaluate the deterioration in balance function. It is a valid tool used in clinical practice and research for the evaluation of the effectiveness of interventions and quantitative definitions of function. It consists of 14 items that are scored by observing performance. A ruler, stopwatch, step, chair and 15-20 minutes are required for the application. The highest score is 56. 0-20 indicates balance disorder, 21-40 indicates acceptable balance, and 41-56 indicates good balance.

To perform the Time Up-Go test, the patient rises from a chair, walks at a comfortable and safe pace to a line on the floor three meters away, turns, and sits back in the chair. The test is attempted once to become familiar with the test. If the patient uses a walking aid, they can perform the test with it. A shorter time indicates better functional performance. A test score of ≥13.5 seconds indicates those at high risk of falling in the community setting. However, threshold values reported in the literature range from 10 to 33 seconds

A 6-minute walk test was used to evaluate the exercise capacity of elderly individuals. The 6MWT is a well-known, valid, and reliable measure of aerobic capacity in elderly people with heart, peripheral vascular, and respiratory diseases. The 6MWT has also been used as an indicator measure of submaximal aerobic capacity in the elderly population. The test should be performed in a flat, hard-surfaced corridor at least 30 meters long. The patient is told to be calm, have taken their medications, and wear comfortable clothes and shoes. Once the patient understands the instructions, they are ready to begin the test. Vital signs are recorded before starting the test. During the test, participants must walk at a pace appropriate to their condition and may stop, slow down, and continue walking as soon as possible if they wish. The therapist may encourage the patient with standard phrases such as 'You're doing well', 'Keep up the good work'. At the end of the test, the therapist measures vita
