In the WHO model, disability is defined as?

• A. Loss of structure or function in the body.
• B. Inability to perform an activity in a normal way due to impairment.
• C. Disease state.
• D. Social stigma unrelated to impairment.

Answer: (B)

Disability in the WHO framework is about limitations in performing activities in daily life that arise because of an impairment. It captures how an impairment leads to not being able to do things in the usual or normal way. This distinguishes it from impairment itself (loss or abnormality of body structure or function) and from a disease state, which is the health condition causing the impairment. Social stigma or environmental barriers can influence participation, but they are not the definition of disability itself. Therefore, the statement describing an inability to perform an activity in a normal way due to impairment best fits the concept.
