What defines an impairment in terms of physical function?

An impairment in terms of physical function is defined as the loss or reduced function of a body part or organ. This means that when an individual experiences an impairment, there is a measurable decrease in the ability of that specific anatomical structure, such as a limb or organ, to perform its normal physiological functions. This definition is fundamental in medical and educational contexts, as it provides a clear basis for identification and assessment of individuals who may need special services or accommodations.

Impairments can manifest in various ways, such as decreased strength, flexibility, or range of motion, which can impact an individual's overall ability to carry out daily tasks but do not directly reference the limitations those impairments may cause in terms of performance.
