• Diplegia :(Arms & Legs much more in legs), most patients eventually walk.
• Tetraplegia :(Arms & Legs & Trunk) High mortality rate, most pts unable to walk. IQ is low.
• Hemiplegia : Upper & lower limbs on one side (upper more than lower limbs), with spasticity, patients eventually walks.
• Bilateral Hemiplegia
• Paraplegia (Legs): implies no upper limb involvement only lower limb involvement
• Monoplegia: involvement of one limb
• Triplegia: involvement of one side of the body, as in hemiplegia, combined with involvement of the contralateral lower limb. The lower limb involvement is always asymmetrical.
• Quadriplegia: involvement of all four limbs and the trunk.

Spastic

• Commonest 50-60%
• Most important for the Orthopedic Surgeon
• Increased muscle tone (Jack knife spasticity)
• Slow restricted movements
• Increased reflexes
• Babinski +ve

Athetosis

• 20-25%
• Kernicterus
• Involuntary, uncontrolled slow movement
• +/-Normal reflexes
• Muscle rigidity or tremors
• NOT FOR SURGERY

Ataxia

• 1-5%
• Inability to control /coordinate movement when they start
• Intention tremor
• Nystagmus / unbalanced gait
• NOT FOR SURGERY

Rigidity

• 5-7 %
• Lead pipe rigidity

Mixed type

• A combination of spasticity and athetosis with whole body involvement
