The WHO has developed a tool called the International Classification of Functioning Disability and Health (ICF). The ICF uses three categories to help describe patients with any kind of health problem. These three measures include: impairments, activity limitations, and participation restrictions. Impairments refers to problems in body functions or structures. This includes the body parts and organs. For example, if your Gramma has a problem with her hearing or vision, she would have a hearing impairment or visual impairment. If her liver wasn't working properly, the doctor might say she has a liver impairment.

Sometimes impairments occur but we aren't affected that much by them. If the affected individual has trouble doing something because of the impairment, then it's called an activity limitation. So if her vision is impaired enough, she may not be able to walk without help from a person, cane, or seeing eye dog. This is an activity limitation.

And, if she has to give up driving because of it, then she has a participation restriction.

Whenever you take your grandmother to see a health care specialist, don't hesitate to ask for explanations. The more the family understands of her situation, the better you'll be able to help her remain independent for as long as possible.
