The
incidence of Spastic cerebral palsy is more common than
the other types of CP. 50% of those identified as having
CP belong to this category. It is characterized by the restriction
in the movement of limbs and occurs usually as a consequence
of damage to the cerebral cortex. The word spastic means"
stiffness in the muscles.
The muscles become taut and very
rigid making the simplest of movements difficult and jerky.
Grasping a particular object or releasing it and changing
positions are tasks that require great effort. Because the
muscles are tight and not amenable to easy movement, they
cannot be stretched easily and awkward movements result.
Whenever normal muscles work, one-group contracts and the
other group relaxes and hence easy movement is achieved.
Spastic muscles are in a state of war and constantly contract
at the same time. To overcome the resistance, the patient
has got to make a tremendous effort. Free movement is thus
hindered.
The
nature of spastic cerebral palsy can range from mild to
severe. If it is mild it restricts only certain movements,
but if it is severe, the whole body can be affected. Therapy,
medication and sometimes-surgical intervention can go a
long way in helping to alleviate the effects of spatiscity.
The
limbs affected in spastic cerebral palsy can vary from individual
to individual. When only one limb is affected (usually the
arm) it is called Spastic monoplegia. If either arms or
legs are incapable of movement, the patient suffers from
what is known as Spastic Diplegia. When both the legs are
affected, the muscles in the hips and legs become so tight
that the legs turn inward and hence cross at the knees producing
a scissors like appearance.
In fact the gait of the individual
is referred to as " scissors gait" Spastic Hemiplegia
as the word suggests is a form of cerebral palsy where one
side of the body (usually the arm more than the lower limb)
is affected. As the right side of the brain controls the
left part of the body and the left side of the brain controls
the right part of the body, the effects of cerebral palsy
are seen in the opposite side of the side of the body. In
spastic Triplegia, 3 limbs are affected.
In Spastic double Hemiplegia, there is stiffness of the muscles on both sides
of the body, but when the right and left side is compared,
the extent of shaking is different. In spastic Tetraplegia,
both sides, the trunk and head are affected, making movement
almost impossible. Children who are affected by Spastic
quadriplegia are usually retarded and have trouble eating,
speaking and swallowing. Tremors of the limbs are also usually
observed.
