Impairment refers to a loss or abnormality in a physical, mental, or sensory function. It can affect various aspects of a person's abilities, such as mobility, vision, hearing, or cognitive skills. Impairments can be temporary or permanent and may result from injury, illness, or congenital conditions. In the context of healthcare, impairment is often assessed to determine the level of support or rehabilitation a person may need. It plays a crucial role in understanding disabilities and can influence treatment plans, accessibility measures, and the overall quality of life for individuals affected by it.
