Muscle Spasticity

Muscle spasticity is a condition characterized by the involuntary contraction or tightness of muscles, which can cause stiffness, pain, and difficulty moving. It is often caused by damage to the nervous system, such as from multiple sclerosis, cerebral palsy, spinal cord injury, or stroke.

In individuals with muscle spasticity, the signals from the brain and spinal cord to the muscles can be disrupted, causing the muscles to contract and become stiff. This can interfere with normal movement and posture, and in severe cases can lead to deformities.

Treatment for muscle spasticity can include medications such as muscle relaxants or anti-spasticity drugs, physical therapy, and assistive devices such as braces or orthotics. In some cases, injections of botulinum toxin (Botox) may be used to temporarily weaken specific muscles and reduce spasticity.

In more severe cases, surgical procedures such as selective dorsal rhizotomy (SDR) or intrathecal baclofen (ITB) therapy may be considered. SDR involves cutting some of the nerve fibers in the spinal cord to reduce spasticity, while ITB therapy involves implanting a pump that delivers a muscle relaxant medication directly to the spinal cord.

Overall, treatment for muscle spasticity is aimed at reducing the tightness and stiffness of muscles, improving mobility and function, and minimizing pain and discomfort.
