The concept of disability varies from society to society, from time to time. Earlier,
the term `handicapped' was used as a substitute for the term `disability', which is
a derogatory term because it is "popularly believed to have derived from the phrase
`cap in hand' referring to the medieval custom where the beggars would extend their
cap to receive the handouts. It, in fact, is a derogatory
term". Generally, impairment, handicap, disability are used as synonymous but, in fact, all these terms are distinct.
Impairment is "an exteriorized loss of structure, or abnormality of function at
the organ level, disability [i]s a restriction of actions at the person level and handicap
[i]s a set of disadvantages within the individual's particular social context". Thus,
three different levels are involved with, in most cases, impairment leading to disability
and disability leading to handicap.
The terms `disability' and `handicap' were often used in an unclear and
confusing way, which gave poor guidance for policy-making and for political action.
The terminology reflected a medical and diagnostic approach, which ignored
the imperfections and deficiencies of the surrounding
society.
National Sample Survey Organization defines disability as:
A person with restrictions or lack of abilities to perform an activity in the manner or within the range
considered normal for a human being was treated as having disability. It excluded illness/injury
of recent origin (morbidity) resulting into temporary loss of ability to see, hear, speak
or move. |
