Prehab is participation in therapy-based movements and exercises in order to avoid injury, decrease pain or to prepare for surgery. It can address deficits in strength, stability, range of motion, balance and overall joint function. With injury or long-term muscle or joint dysfunction, incorrect or inefficient movement patterns and compensatory movements can slip into our normal everyday function. This can cause the deficits mentioned above, which need to be corrected and improved to achieve the best outcomes after surgery. It has been proven that an effective prehab program can improve outcomes, reduce the time to achieve excellent function and reduce complications after surgery. The outcomes can sometimes lead to postponing surgery as function can be significantly improved.
