The Functional Independence Measure (FIM) is a standardized assessment tool used to evaluate a person's level of independence in daily activities. It measures various domains, including self-care, mobility, and communication, providing a comprehensive overview of an individual's functional abilities. The FIM is commonly used in rehabilitation settings to track progress and plan treatment. FIM scores range from 18 to 126, with higher scores indicating greater independence. This tool is essential for healthcare professionals, such as occupational therapists and physical therapists, as it helps in setting goals and determining the effectiveness of rehabilitation interventions.
