Disability is a part of human life. Almost all people
temporarily or permanently will be impaired at some
point in their life. Disability is the umbrella term for
impairments, activity limitations, and participation
restrictions, referring to the negative aspects of the
interaction between an individual (with a health
condition) and that individual’s contextual factors
(environmental and personal factors).[1] According to
global population estimates, around a billion people
(15% of the world’s population) live with some form
of disability.[2] The world health survey results show
that 785 million (15.6%) persons, 15 years and older live
with a disability. Of these, the report estimates that 110
million people (2.2%) have very signifi cant diffi culties
in functioning.[2
