What is the difference between massage therapy and deep tissue massage therapy?

[Hanna10]

Hi, my brother is recovering from an accident. He met with an accident six months back. Now the injuries are almost cured. He had undergone two surgeries on his left leg. The doctor suggested massage therapy treatments after this recovery period. We are in search for a therapy clinic in Toronto. One of his friends suggested a deep tissue massage therapy for him. His father has taken this treatment after an accident. And was effective in their case. Anyways we are planning to take him to a clinic for massage therapy treatments. Before taking the treatment, I would like to know the difference between massage therapy and deep tissue massage therapy? Please share your views.
