Plegia
Pronunciation: PLEE-jee-ah
Complete loss of voluntary motor function in the affected body region, contrasted with 'paresis,' which denotes partial loss only.
Full Definition
Plegia indicates total absence of voluntary muscle movement and is used in PM&R with anatomical prefixes: monoplegia, paraplegia, hemiplegia, and quadriplegia/tetraplegia. It is essential for editors to preserve this distinction from paresis because the two terms imply different levels of impairment, rehabilitation goals, and resource needs. Documentation errors in which 'plegia' and 'paresis' are swapped can affect insurance authorisations, disability ratings, and ICD coding. The term appears in physiatric consultation notes, spinal cord injury classification reports (using the ASIA Impairment Scale), and functional outcome documentation.
Usage
Usage note: Distinguish carefully from 'paresis' (partial loss). Editors should verify the anatomical prefix and confirm consistency with the strength findings documented elsewhere in the chart.
In Context
- "The ASIA classification confirmed motor-complete tetraplegia below the C5 level." — Spinal Cord Injury Classification Report
- "The copyeditor queried whether 'paraplegia' was correct or whether 'paraparesis' was intended, given the residual lower-extremity movement noted in the examination findings." — Medical Records Editing Query
