Paresis
Pronunciation: puh-REE-sis
Partial paralysis or weakness of voluntary muscle movement, typically resulting from nervous system damage.
Full Definition
Paresis refers to partial loss of motor function characterized by muscle weakness rather than complete paralysis. This condition commonly occurs following stroke, spinal cord injury, or other neurological disorders affecting the central or peripheral nervous systems. Physical therapists assess the degree of paresis using standardized strength testing and develop treatment programs focused on strengthening, motor re-education, and functional training to maximize recovery potential and compensate for residual deficits.
Usage
Usage note: Often used with anatomical descriptors (hemiparesis, monoparesis).
