Physiotherapy treatment aims to give support to you. Treatment is different and unique to each person and their pain. There is no one recipe to treat everybody.
When you get hurt or sick, this happens to you in a different way to anyone else. Your memories, ideas, experiences and perceptions are individual to you. So if two people get the same injury, it will always be different because of all these other things. The support you get from physiotherapy is also affected by what you believe, who has treated you and what they believe, and by their skills.
