Fatigue is a common symptom in older adults, often linked to various medical conditions, medications, and psychosocial factors, and it can adversely affect both physical and cognitive performance in the aging population, contributing to functional decline and reduced quality of life.

Assessment of the physical impact of fatigue on physical and cognitive performance in older adults can offer valuable insights for clinical practice and holistic geriatric care. Therefore, this study will validate subjective tools used for measuring the impact of fatigue against objective measures.
