Monoplegia : One limb
Triplegia : Three limbs

Paraplegia : Only legs involved

•Physiological classification (according to the major motor abnormalities):

Spastic CP : (70 to 80% )

Hypertonia with hyperreflexia

Positive babiniski sign ( extensor plantar response

Persistent primitive reflexes.

Dyskinetic CP: (10 to 20%)

Abnormal movements and/or change in tone (increased or decreased).

Rigidity: hypertonia with hyporeflexia or normal reflexes.

Chorea: quick irregular dysrythmic movements involve proximal skeletal

muscles.

Athetosis: slow twisting movements, usually along long axis of a limb, more

prominent distally.

Choreoathetosis: Chorea and Athetosis are commonly seen.

Dystonia: painful sustained contraction of a muscle group's → prolonged,

twisting, posturing of the face, limb or trunk, which involved.

Ataxic CP (5 to 10%): Disturbaces in balance and equilibrium: walk

unsteadily, poor coordination and balance often with hypotonia, hyporeflexia,
nystagmus.

Atonic (hypotonic) CP: Floppy infant with hyperreflexia, usually with marked

mental retardation.

Mixed forms : spaticity and ataxia may coexist.
