We understand Handicap child as:

A handicapped child refers to a child who faces challenges in performing daily activities due to physical, intellectual, sensory, or developmental impairments. These disabilities can affect mobility, communication, learning, or self-care, requiring special support and interventions.

 Key Points

• The term "handicap" generally refers to conditions that limit a child's ability to function independently in different aspects of life.
• Physical disability is a primary characteristic that defines a handicapped child, as it directly impacts mobility, motor skills, or bodily functions.
• Children with physical disabilities may experience difficulty in movement, coordination, or performing routine tasks, often requiring assistive devices or support therapy. Conditions such as cerebral palsy, muscular dystrophy, and limb deformities fall under this category.

Thus, it is concluded that we understand handicap child as Physical disability.

Hint

•  An IQ lower than normal is associated with intellectual disabilities rather than physical handicaps, and an IQ higher than normal indicates giftedness rather than a disability.
• Since handicap primarily refers to physical limitations, IQ variations do not define a handicapped child.
