What is a Disability?

Disability results from the interaction between people with impairments and societal obstacles, such as physical barriers and even people’s attitudes. These barriers can get in the way of a person with disability participating in society. By tackling the barriers in the environment, we can (and should) remove some of the challenges faced by persons with disabilities.

One person’s experience of a disability is rarely the same as another’s, even if they have the same type of disability. It is important to remember that everyone’s story is unique and the best way to find out how someone feels about disability is to get to know that person and in a respectful and appropriate manner ask them what they are willing to share with you.

There is rich diversity within the disability community and it is helpful to remember that there is a wide spectrum of impairments. For example, not all wheelchair users have the same mobility, some may have a lot of function in their hands and arms and others may only have mobility in their neck and head. Persons who have intellectual disabilities vary greatly in their cognitive ability and not persons who have autism spectrum disorder exhibit the same behaviour and abilities. People who have vision impairment can have a wide range of sight related issues and the effect of them can range from low vision to blindness. People can even have more than one impairment and are said to have multiple disabilities.

Having a disability does not define an individual, yet it is also an important part of how they experience and interact with the world.

Physical Disability

What is it?

Physical impairment pertains to:

  • A total or partial loss of a person’s bodily functions (e.g. walking, fine or gross motor skills)
  • A total or partial loss of a part of the body

People who use wheelchairs have different abilities. Some are able to use their arms and hands, or get out of their wheelchairs, or walk for short distances.

Hearing Impairment

What is it?

Deafness is the partial or complete loss of hearing in one or both ears.

Levels of Hearing Loss

41 to 70 dBS
Moderate hearing loss
Has difficulty hearing conversation, especially with background noise. May use a hearing aid to amplify sounds.
71 to 90 dBs
Severe hearing loss
Normal conversations will not be audible. Loud speech is also difficult to hear or understand.
91 dBs and above
Profound hearing loss
Difficulty in understanding even amplified speech. May not be able to distinguish any sounds.

Did you know?

‘Deaf’ with an upper-case ‘D’ refers to persons or a community of persons with hearing loss who have chosen to communicate primarily through sign language.

‘deaf’ with a small letter ‘d’ is a general term used to describe people who have a physical condition of hearing loss, whether or not they communicate through sign language.

Visual Impairment

What is it?

Visual impairment is significant visual loss that cannot be corrected to a normal level by medication, surgery or the use of optical lenses such as spectacles.

Visual Function

Examples of what visually impaired people see

Autism Spectrum Disorder

Significant limitations in adaptive functioning
