Sports injury therapy is the name given to any treatment used in the recovery of injuries in sport. Most common therapies include; massage including sports, deep tissue, physiotherapy, chiropractic.
It would depend which treatment was needed depending on the specific injury. ie if you had strained a muscle it would benefit more to go to a massage therapist, if you had a problem with a joint then a physio would fit you best.
Problems with the spine would best suit a chiropractor. If in doubt speak to the therapist you choose and if they are not the right person for you they will refer you to someone more specialised to your condition.
