External environmental factors (ICF) include which of the following?

• A. Attitude of patient
• B. Mobility and self care
• C. Products and technology, assistive devices, tools, ramps, stairs, etc
• D. Sensory functions

Answer: (C)

In the ICF framework, environmental factors are the external elements outside the person that can enable or hinder functioning, such as the built environment and the tools and devices available. The option that lists products and technology, assistive devices, tools, ramps, stairs, and similar items directly shows how the environment and its resources impact daily activities and participation. Attitude of the patient is a personal factor, not an environmental one. Mobility and self-care describe activities rather than environmental influences. Sensory functions are about body functions, not the surrounding environment. Therefore, this option best represents external environmental factors.
