Spastic cerebral palsy is the most common type of cerebral palsy. The approximate percentage of spastic cerebral palsy patients among all CP patients is 70%. Spastic CP is basically related with muscles dysfunction.

The functionality of muscle is depending on pair of nerves or you can assume it as an electricity wire. The function of first nerve is to transfer signals from muscle to brain and the function of second nerve to carry signals from brain to muscle. Both the nerves follow each other and works simultaneously. For example if a muscle is tight in body then one set of nerve inform the brain about the tightness at the same time brain send a message to relax the muscle through second set of nerves. Such messages transfers go on all the time, for better functionality of muscle.

Now if the message transfers are smooth then there is no problem but whenever there is a condition of traffic jam due to flood of these messages; the concerned muscle have tenseness or you can say it is not be able for proper movement. This disorder is called spastic cerebral palsy. In spastic cerebral palsy the gray matter (where nerves are located) and cerebral cortex are damaged which cause the malfunctioning to muscle. Due to spastic cerebral palsy the muscle affected area become rigid and stiff too much which causes jerky movement.

There are five types of spastic cerebral palsy depending on the affected part of body.

Quadriplegia – In this type of spastic cerebral palsy torso and all the four limbs are affected.

Diplegia - In this type of spastic cerebral palsy any of the one pair of limbs is affected. Either both legs or both hands. Diplegia spastic cerebral palsy is the most common cerebral plasy.

Hemiplegia – In this type of spastic cerebral palsy only single side of body is affected.

Triplegia – In this type of spastic cerebral palsy in which three limbs are affected.

Monoplegia – In this type of spastic cerebral palsy only single limb is affected.

Monoplegia and triplegia cerebral palsy are very rare and found in very few patients.

The major property of spastic cerebral palsy is, it change with time. So is there is no treatment for spastic cerebral palsy it is possible that patient may suffered from permanent disabilities. Spastic cerebral palsy is the disorder of rigidity of muscles, which is treated if there is an early treatment.
