Corrective exercise is not physical therapy, and im not attempting to rehabilitate injured clients, whom are beyond my purview.

Training on unstable surfaces can be useful, and is synonymous with corrective exercise, but is not the main course. It can lead to faulty motor patterns, decreased power. Both can alter movement negatively.

The term ‘functional training’ is overused and a misnomer, as these movement patterns rarely have much in common with the real life movements. They can be useful, but not as prescribed my many trainers.

Good corrective exercise will work towards good technique being its own corrective. If an exercise cant be performed optimally, then regressions are made, but maintaining the same (or very similar) movements as the goal. Muscle activation is often required, which can take time.
