Injured leg while practicing

Hey!! My younger brother is a baseball player. A few months back he injured his legs while practicing for inter-college competition. After a gap of a month, he started to practice again and says he is finding difficult to run. I researched and saw that physiotherapy treatment is considered for the sports injury. Is it true? If so there is a nearby physiotherapy clinic in Don Mills ( Physiotherapy Treatment & Rehabilitation Centre Toronto | Physiomobility ), I could take my brother asap. Please share your thoughts!! Will my brother able to run without pain after undergoing this treatment? Is there anything else we could do?
