Role of botulinum toxin in cerebral palsy

<strong>Cerebral Palsy : what happens with the muscles?</strong>
In cerebral palsy, the brain loses the ability to moderate the activity of contracting muscles. Muscles that produce contraction are stronger than those that produce extension, Partially paralyzing the stronger muscles with botulinum toxin gives patients an opportunity to stretch and strengthen the weak muscles. The long-term goal of the two components of the treatment – injections and physical therapy – is to achieve b etter muscle strength balance which may lead to restoring normal function.

<strong>How does Botox help in Cerebral palsy ?</strong>
The marriage of botox and cerebral palsy may seem odd at first, but is actually quite practical. When prepared for therapeutic use, botox is injected in small amounts into the spastic or stiff muscles. It begins to take effect by blocking transmission between the nerves and the affected muscles. The injection stops the signal between the nerve and the muscle, relaxing the muscle and reducing stiffness. Botox only affects the muscles that are injected and once the muscles are relaxed, therapists are able to stretch the muscles and stimulate normal growth.
Botox injections can offer many benefits including ease in stretching, improvement in child’s range of motion, tolerance to wearing braces and developmental improve ments in crawling, standing, or gait changes.

<strong>Who respond the best to Botox?</strong>
Children under the age of six respond best to this type of cerebral palsy treatment, especially effective in children who have not developed fixed joint contractures. It is most effective when used in the early stages of spasticity while the child’s bones are still developing and before problems with bone development and deformity set in.
<strong>Precaution to be taken after Botox injection</strong>
Since this treatment changes muscle tone , your child may initially miss some of the support that they relied on from their increased tone. Therefore, until your child gets used to these changes, we recommend close supervision in situations where they may be at increased risk of falling. This might include going up and down stairs, walking in halls, or other busy areas. Other than this precaution, there are no restrictions following the injections and normal activities can be resumed…
<strong>What are the advantages of Botulinum toxin</strong>

· can be done without anesthesia
· easy to administer
· essentially painless
· effects wear off
· most side-effects are minor
· can be repeated in 6 months

<strong>Role of physiotherapy</strong>

Physiotherapy, which involves the use of stretching, strengthening, casting,bracing, positioning and facilitation of movement, is an essential part of the treatment plan for children with cerebral palsy. These forms of treatments assist
children in developing muscular control, better balance and mobility.
Ability ofthe parent or carer to assist their child in becoming as physically independent as possible is enhanced by physiotherapy. A range of motion exercises, tailoredfor each child help improve strength, maintain muscle length and improve movement of joints. Exercises can help strengthen muscles and improve physical stamina, preventing the weakening and wasting of under used muscles. This further reduces the risk of developing fixed contractures.
