Spasticity is essentially abnormal muscle tightness resulting from prolonged muscle contraction. It's a condition characterized by increased muscle tone, stiffness, and involuntary muscle spasms.
Understanding Spasticity
Spasticity isn't just simple muscle stiffness. It's a neurological issue stemming from damage to the brain, spinal cord, or motor nerves. This damage disrupts the normal communication between the brain and muscles, leading to the overactivity of muscles.
Causes of Spasticity
As the provided reference points out, spasticity is often seen in individuals with neurological conditions, such as:
- Cerebral palsy (CP)
Other causes can include:
- Stroke
- Multiple sclerosis (MS)
- Traumatic brain injury
- Spinal cord injury
Characteristics of Spasticity
Spasticity can manifest in various ways, including:
- Increased muscle tone
- Muscle stiffness
- Involuntary muscle spasms
- Clonus (rapid, involuntary muscle contractions and relaxations)
- Pain
- Difficulty with movement and coordination
Impact of Spasticity
Spasticity can significantly impact a person's quality of life, affecting:
- Mobility
- Daily activities (dressing, bathing, eating)
- Sleep
- Speech
- Bowel and bladder control
Management of Spasticity
While there is no cure for spasticity, various treatments can help manage the symptoms and improve function, including:
- Physical therapy: Stretching exercises, range-of-motion exercises, and strengthening exercises.
- Medications: Muscle relaxants (e.g., baclofen, tizanidine), nerve blocks (e.g., botulinum toxin injections).
- Orthotics: Braces or splints to support and position affected limbs.
- Surgery: In severe cases, surgery may be an option to release tight muscles or tendons.
