Functional capacity refers to an individual's ability to perform tasks and activities necessary for daily living. It encompasses physical, mental, and social capabilities, reflecting how well a person can manage their responsibilities and engage in their environment. Assessing functional capacity helps identify strengths and limitations, guiding interventions and support. Evaluations of functional capacity often involve standardized tests and assessments, which may include measures of strength, endurance, and cognitive function. These evaluations are crucial in various fields, such as rehabilitation, occupational therapy, and geriatrics, to tailor care plans and improve overall quality of life for individuals.
