People often equate rehabilitation with physical therapy. It’s something a patient does following an injury or surgery. Rehabilitation is also something that one does after a catastrophic injury or illness, such as having a stroke, a traumatic brain injury, spinal cord injury, or long-haul COVID. Still others think of rehab as a treatment for alcoholism or drug addiction. Rehabilitation can also be a form of vocational counseling. Injured workers re-learn how to go back to work in what’s called vocational rehabilitation.
