Spasticity
Pronunciation: spas-TIS-ih-tee
Velocity-dependent increase in muscle tone causing stiffness and involuntary contractions.
Full Definition
Spasticity is a neurological condition characterized by abnormally increased muscle tone that worsens with rapid movement. It results from damage to the central nervous system, commonly seen in conditions like stroke, multiple sclerosis, cerebral palsy, and spinal cord injury. Physical therapists assess spasticity using scales like the Modified Ashworth Scale and employ various treatment techniques including stretching, positioning, and specialized interventions to manage its effects on function and comfort.
Usage
Usage note: Often confused with 'rigidity' but spasticity is velocity-dependent while rigidity is not.
