Classification Systems for CMD• Many classification systems have been

developed over the years.• Important that clinicians working with children

with CMD use a common language when communicating with each other.

• Provides tools for physiotherapists to make their own clinical diagnosis & confirm or question diagnoses already made by another healthcare provider.

Remember clinical picture can change over time!!! ....but the lesion/damage sustained to the brain cannot

What are we talking about if we are talking about “tone”?

• Muscle tone refers to the resting tension in a muscle or the amount of tension or resistance to movement in a muscle.

• Muscle tone is what enables us to keep our bodies in a certain position or posture against gravity.

• Changes in muscle tone are what enables us to move to smoothly and in a coordinated manner

What are they talking about hypertonicity, spasticity and rigidity
