2.2. Definition of Disability

Disability refers to any condition that restricts a person's mental, sensory, or mobility functions to undertake or perform an activity in the manner considered normal for a human being.

This definition outlines what disability means in a broad sense. It emphasizes that disability can affect various aspects of a person's function, including mental abilities (like thinking and learning), sensory functions (like seeing and hearing), and mobility (the ability to move). If any of these functions are restricted, it can influence a person's ability to perform everyday activities in ways that are generally expected or typical in society.

Think of a person trying to participate in a sport. If someone has a condition that restricts their movement (like a knee injury), they won't be able to play the game like others. This is similar to how disabilities can impact everyday tasks for different people.

According to the World Health Organization (WHO): “Disability is an umbrella term for impairments, activity limitations, and participation restrictions. It denotes the negative aspects of the interaction between an individual’s health condition and contextual factors.”

Here, the WHO provides a more nuanced definition of disability. It recognizes that disability encompasses not just the physical or intellectual impairments but also how these impairments limit a person's activities and participation in society. The term 'contextual factors' includes environmental, social, and personal elements that can affect how disabilities impact individuals. For example, a person with a mobility impairment may struggle more in a city without ramps or elevators.

Imagine someone in a wheelchair. If they live in an area with accessible ramps and elevators, they may be able to participate fully in community activities. However, if they live in an area with many stairs and no ramps, their ability to engage with society is restricted, illustrating the role of contextual factors.

According to the Rights of Persons with Disabilities Act, 2016 (India): 'A person with disability means a person with long-term physical, mental, intellectual, or sensory impairment which, in interaction with barriers, hinders his full and effective participation in society equally with others.'

This definition from the Indian legislation specifically highlights that a disability can stem from long-term impairments in various forms, including physical and mental aspects. It also emphasizes that it is the interaction between these impairments and barriers in society that ultimately determines whether a person can participate fully. This points to the importance of removing barriers in the environment, ensuring that everyone has equal opportunities.

Consider a student who is visually impaired. If their school provides braille materials and has audio descriptions for lessons, they can participate effectively just like their peers. However, if these resources are not available, they face barriers that hinder their learning and participation.
