Spasticity is a muscle control disorder where certain muscles are continuously contracted. It results in tight or stiff muscles and the inability to control them. This condition can interfere with a person’s normal movement or speech. It is usually caused by damage to the part of the brain or spinal cord that controls voluntary movement.

Spasticity is especially common in patients with cerebral palsy and multiple sclerosis. Other conditions that may cause spasticity include:

  • Traumatic brain injury (TBI)
  • Spinal cord injury (SCI)
  • Brain damage due to a lack of oxygen
  • Stroke
  • Encephalitis
  • Meningitis
  • Adrenoleukodystrophy
  • Amyotrophic lateral sclerosis (Lou Gehrig's disease)
  • Phenylketonuria

Symptoms of spasticity include:

  • Increased muscle tone
  • Overactive reflexes
  • Involuntary movements, which may include muscle spasms
  • Pain
  • Decreased functional abilities and delayed motor development
  • Difficulty with care and hygiene
  • Abnormal posture
  • Bone and joint deformities
