Pre-existing soft tissue/joint injuries

About 1/3 of the clients I have deal with some type of pre-existing soft tissue/joint injuries. These injuries are either seen during assessment, exposed during exercise (then clients admits to having prior injury), or expressed by client during consultation. I try to target the area with different exercises during warm-up/prehab to help strengthen the joint/muscle using corrective exercises. Some of the injuries affect basic movement patterns limiting exercise program/progression. I recommend clients to see PT to help injuries if they are not already doing so but some cannot afford, don't want to see a PT for whatever confidential reason, or have a reason/excuse why they can not go. How do you handle these types of situations/clients? Anything you can recommend?
