Early clinical rehabilitation refers to the functional recovery that patients undergo after 48 hours of their condition stabilizing and symptoms no longer worsening. It is an enhancement and continuation of clinical treatment, emphasizing multidisciplinary collaboration and widely applied in fields such as critical care medicine, neurology and neurosurgery, orthopedics, and rehabilitation medicine.

Early clinical rehabilitation can not only effectively prevent complications caused by bed rest, but also maximize the recovery of patients' functions, prevent secondary disabilities, shorten hospitalization periods, optimize medical resource allocation, and enable patients to return to their families and society as soon as possible.
