Background technique

Clinical refers to the direct contact with the patient and the actual observation of the patient. The clinical department is the main body of the hospital, and it is directly responsible for the admission, diagnosis and treatment of patients; clinical personnel include doctors and nurses who directly participate in the treatment and care of patients; the medical technology department is the "non-clinical" department in the past, It also has doctors and nurses, but they are not directly involved in the treatment and care of patients, but provide services directly for clinical diagnosis and treatment. The main job of medical staff also includes clinical care.

Comatose patients with craniocerebral injury are often complicated by limb dysfunction. During the clinical nursing process, medical staff should pay attention to observe whether the patients have voluntary activities and whether there are signs of hemiplegia. Physical activity and exercise can prevent disuse syndromes such as muscle atrophy, contractures, and joint disorders, and help patients recover quickly. There are many methods of physical rehabilitation training, the main principle is the early scientific and step-by-step through treatment. During the treatment process, corresponding physical means can be used to assist in training. For example, in the early stage of disease treatment, the muscles of adjacent parts can be used for isometric contraction; during the recovery period, the injured part of the exercise can be appropriately added, but it must not be too hard; Corresponding functional training on the bed can also be carried out, such as physical therapy, acupuncture, massage and other physical therapy methods; rehabilitation training can be carried out after disease treatment, and various limb movements and strength exercises can also be used. In addition, you can also choose occupational therapy, which is to carry out rehabilitation training through daily work, study and activities. During this period, you can also assist physical therapy such as electric roasting, acupuncture, moxibustion, spectrum irradiation, massage, and wax therapy. More effective rehabilitation training. Limb rehabilitation device is a commonly used therapeutic instrument in rehabilitation department to restore limb motor function. There are many types of limb rehabilitation device.
