The so-called sports rehabilitation is the process of restoring some injured parts to their original normal sports state through some appropriate sports means. Generally speaking, different groups of people have different rehabilitation programs, such as the elderly, children, the disabled, and some people with functional disabilities. The hospital will evaluate the injury degree of the corresponding person, then discuss with the family members the degree of recovery that needs to be achieved, and formulate a special plan based on the actual situation of the patient, with the aim of restoring the original motor function of the patient as low as possible. In fact, this is the "physical therapy" that we often see in some film and television works.
Using exercise to restore the injured place is called sports rehabilitation. Of course, you don't have to recover from sports injuries, and you should rest if you sprain your ankle playing basketball.
