Spasticity
The term spasticity refers to reactive over contraction of muscles
usually involving the limbs. It is often associated with dysfunction or
compromise of neurological pathways within brain and/or spinal cord. Muscle
spasticity is often perceived as stiffness or rigidity of the limb. Spasticity can develop
secondary to numerous causes including stroke, tumor, demyelinative disease,
and as the result of spinal cord compression. The most common causes of
spinal cord compression include disc herniation and spinal stenosis. The rapid
onset of muscle spasticity and muscle weakness in one or more limbs may
constitute a medical emergency.
