The document discusses disablement, its process, and common models used to describe it. It defines disablement and outlines Nagi, ICIDH, and ICF models of the disablement process. These models progress from pathology and impairment at the tissue/organ level to functional limitation and disability at the personal level to participation restrictions at the societal level. The document also discusses how therapeutic exercise can impact different levels of the disablement process by reducing impairments and improving function. Common physical therapy impairments, limitations, activity categories, and risk factors are also outlined.

- 3. 1. DISABLEMENT Definition: “ It is a term that refers to the impact(s) and functional consequences of acute or chronic conditions, such as disease, injury, and congenital or developmental abnormalities, on specific body systems that compromise basic human performance and an individual’s ability to meet necessary, customary, expected, and desired societal functions and roles.” DR. QURATULAIN MUGHAL 3
- 4. 2. THE DISABLEMENT PROCESS 1. The process is not unidirectional (it is not necessarily unpreventable or irreversible). 2. It is assumed that in most instances, it depends on factors such as the severity and duration of the pathological condition. 3. Also depends on the motivation and desires of the patient. DR.

- 10. INTERNATIONAL CLASSIFICATION OF FUNCTIONING, DISABILITY, AND HEALTH (ICF) MODEL The ICF model consists of the following components of health and health-related influences: 1. Impairment of body structure (anatomical) and function (physiological). 2. Activity limitation. 3. Participation restriction. 4. Impact of contextual factors (environmental and personal) on functioning, disability, and health DR. QURATULAIN MUGHAL 10
- 11. 5. USE OF DISABLEMENT MODELS AND CLASSIFICATIONS IN PHYSICAL THERAPY 1. Provided an appropriate framework for clinical decision making in practice and research. 2. To standardize terminology for documentation and communication. 3. Can help to prevented, eliminated, or reduced the risk of occurrence or severity of pathology, impairment, or functional limitation. 4. Shows the effective interventions, in particular therapeutic exercise. DR. QURATULAIN MUGHAL 11

- 13. Pathology/Pathophysiology: refers to disruptions of the body’s homeostasis as the result of acute or chronic diseases, disorders, or conditions characterized by a set of abnormal findings (clusters of signs and symptoms). Impairments: they are the consequences of pathological conditions; that is, they are the signs and symptoms that reflect abnormalities at the body system, organ, or tissue level. They can be (direct/primary impairments)or(indirect/secondary impairments). The combination of primary or secondary impairments, the term composite impairment is sometimes used. Functional Limitations: occur at the level of the whole person. The term now used by the WHO to denote functional limitation is “ability limitation,” as defined in the ICF model of functioning and disability. Disability: is the inability to perform or participate in activities or tasks. Prevention: reduction of the severity or duration of existing disease. Risk Factors: related to disablement are influences or characteristics that predispose a person to the process of disablement. DR. QURATULAIN MUGHAL 13

Editor's Notes
- #6: The first two schema developed were the Nagi model and the International Classification of Impairments, Disabilities, and Handicaps (ICIDH) model for the World Health Organization (WHO). The National Center for Medical Rehabilitation Research (NCMRR) integrated components of the Nagi model with the original ICIDH model to develop its own model.
- #9: WHO developed the International Classification of Functioning, Disability, and Health (ICF).
