Diplegia
Pronunciation: dy-PLEE-jee-uh
Paralysis or motor impairment affecting symmetrical parts of the body, most commonly the lower limbs, as seen in spastic diplegia associated with cerebral palsy.
Full Definition
Diplegia refers to a bilateral distribution of motor dysfunction in which corresponding body parts on both sides are affected, with the lower extremities typically more involved than the upper. It is most frequently encountered in rehabilitation literature in the context of cerebral palsy, where spastic diplegia is a major subtype. In physiatric documentation, precise use of 'diplegia' distinguishes the pattern from hemiplegia (one side) or quadriplegia (all four limbs). Editors working on rehabilitation case reports or paediatric physiatry texts must be alert to this distinction. The term is sometimes incorrectly used interchangeably with paraplegia, which implies complete lower-limb involvement due to spinal pathology.
Usage
Usage note: Always qualify with the type of motor dysfunction (e.g., spastic diplegia) for clinical precision. Do not use as a synonym for paraplegia.
In Context
- "The patient's spastic diplegia was classified using the Gross Motor Function Classification System prior to rehabilitation goal-setting." — Paediatric physiatry clinical report
- "Authors frequently confuse diplegia with paraplegia; the former is a distribution pattern, while the latter implies a specific spinal aetiology." — Editorial annotation on a manuscript
