Sub-acute rehab is for survivors who can't go home and who can't perform three hours of rehab daily. Usually, people in these skilled nursing facilities receive an hour to 90 minutes of rehab a day. Although orders for care will come from a doctor, the family or caregiver will generally interact with nurses and therapists. The links in this part of the chain are allied healthcare professionals (medical professionals who work together to achieve a common goal) such as PTs, OTs, speech therapists, and nurses.
