Frailty, Dual-Task Performance, and Activities of Daily Living in Older Adults

• Dual Task (Other): The Dual Task Questionnaire will be used to obtain information about the difficulties individuals experience when performing tasks that require dual tasks in situations they encounter in daily life. The dual-task questionnaire consists of 10 questions. The questions will be read to the subjects in order, and there will be no time limit for them to answer. If geriatric individuals do not understand a question, the necessary explanations will be provided and the question will be repeated. Each question is scored as very often (4), often (3), occasionally (2), rarely (1), and never (0). The answers to all questions are added up, the total score is calculated, and divided by 10. Lower scores indicate better dual task performance.

Primary outcomes

• Frailty [Baseline]: Edmonton Frailty Scale: The scale was developed to measure frailty in older adults and is suitable for routine use by healthcare professionals without specialized training in geriatrics or gerontology. The scale assesses a total of 17 points under 11 headings, including cognitive status, general health, dependency, social support, medication use, nutrition, mood, continence, and functional performance. Fragility increases as the score rises
• Daily Living Activities [Baseline]: The Katz Activities of Daily Living Index is the best known measure in clinical practice and the most widely used measure in clinical research. This scale, which will be used to assess participants' level of independence in basic ADLs, includes 6 basic activities: bathing, dressing, toileting, transfers, continence, and eating. Each activity is rated as independent (1 point) or dependent (0 points). The total score ranges from 0 to 6. Higher scores mean greater independence.
• Dual Task Performance (Motor-Cognitive) [Baseline]: Motor-Cognitive performance will be assessed using the Timed Up and Go test and motor-motor performance by carrying a tray with water-filled cups while walking.
• Dual Task Performance (Motor-Motor) [Baseline]: Motor-motor performance by carrying a tray with water-filled cups while walking.
