What is the term for any functional disability?

The correct term for any functional disability is "dysfunction." This term specifically refers to an impairment or abnormality in the performance of a physical or mental function. In the context of physical therapy, dysfunction encompasses various issues that hinder the proper execution of daily activities or specific tasks, indicating that the body is not functioning optimally.

Understanding dysfunction is crucial in physical therapy as it helps professionals identify the underlying problems affecting a patient's mobility, strength, or coordination, allowing them to develop targeted treatment plans.

While "disability," "impairment," and "limitation" are related terms, they have distinct meanings. A disability can encompass a range of limitations in performing everyday activities, often assessed in legal or social contexts. Impairment generally refers to a loss of normal function or ability in a body part but does not always translate directly to a functional disability. Limitation specifically refers to restrictions in a person's ability to perform activities compared to what is considered normal, which is slightly different from the broader context of dysfunction. Thus, dysfunction is the most encompassing term related to functional disabilities.
