Can a person with cerebral palsy start to walk on their own with pt?

Maybe. CP is a diverse condition so no one answer fits for all. Some kids will be able to achieve better posture & mobility with PT while others do not.Sometimes it becomes a matter of giving them a chance to develop the mobility they want over a specific time frame. As they get older, they often decide the lure of walking like everyone else fades when they realize they can move faster in a chair.
Possible. depends on the extent of the motor handicap, many people with cerebral Palsy will be indipendently ambulatory.
