According to the Nagi model of disability, what does the inability to run due to heel pain result in?

• A. Impairment
• B. Functional limitation
• C. Disability
• D. Disorder

Answer: (C)

The Nagi model of disability outlines the interaction between medical conditions and the resulting impact on an individual's life. Within this framework, the inability to run due to heel pain is primarily classified as a disability.

Disability refers to the broader societal and personal impact that results from an impairment or a functional limitation. In this case, the heel pain represents a physical impairment that affects the individual's ability to perform the activity of running, leading to a functional limitation. When the functional limitation prevents the individual from participating in what they might consider normal activities, such as running, it culminates in a disability. This reflects a significant aspect of the Nagi model wherein the inability to engage in desirable activities signifies a disconnect between a person's abilities and societal expectations.

The other concepts—impairment, functional limitation, and disorder—play roles in the overall understanding of health and disability but do not fully capture the interaction and impact illustrated by the inability to run due to heel pain as framed by the Nagi model. An impairment is the physical issue (e.g., heel pain), a functional limitation would describe the difficulties faced in running or walking, and a disorder generally points to a pathological condition, which may lead to impairment or functional limitations but does not encompass the broader social context
