Rehab

Is it necessary to work core specifically, or does Deadlift, Squat, Running and Handstands work core enough?
It seems to me, from what I can see around the gym these days, is that PTs are coming from an orthopedic angle when it comes to training their clients. Rather than ‘training’, it seems more like rehabilitation. Do PTs think that Average Joe Office Worker needs rehab, before they consider them able to ‘train’?
