Which of the following best describes the term "disability" in Nagi's model?

In Nagi's model, "disability" is best described as a significant reduction in the ability to perform daily activities. This definition emphasizes the impact of health conditions on an individual's functional capabilities rather than merely the presence of a physical impairment or medical condition. The focus is on how these conditions can hinder a person's ability to engage in routine tasks and participate in societal roles, thus affecting their overall quality of life.

Understanding disability in this context helps highlight the distinction between impairment (the actual loss or abnormality of anatomical, physiological, or psychological structure) and the resultant disability, which refers to the limitations in functioning in one's daily life. This perspective underscores the importance of both medical and social factors in evaluating disability, supporting a more holistic approach to health and rehabilitation.
