Spasticity is a condition in which there is an abnormal increase in muscle tone or stiffness of muscle, which might interfere with movement, speech, or be associated with discomfort or pain. Spasticity is usually caused by damage to nerve pathways within the brain or spinal cord that control muscle movement.
Symptoms of spasticity can vary from being mild stiffness or tightening of muscles to painful and uncontrollable spasms. Pain or tightness in joints is also common in spasticity.
- Muscle stiffness, causing movements to be less precise and making certain tasks difficult to perform
- Muscle spasms, causing uncontrollable and often painful muscle contractions
- Involuntary crossing of the legs
- Muscle and joint deformities
- Muscle fatigue
- Inhibition of longitudinal muscle growth
- Inhibition of protein synthesis in muscle cells
