Sensory Modality Assessment and Rehabilitation Technique (SMART) is one of the tools for assessing patients with disorders of consciousness (DOC) after brain injury, to detect signs and meaningful responses to the conscious presence of DOC patients, and to optimize the patient's potential communication and motor function through the development of a treatment plan, that can be used in the assessment, treatment, and long-term prognosis of patients with DOC. SMART can effectively reduce the misdiagnosis of DOC due to the environment, long observation and evaluation, the incorporation of family and care teams in the evaluation, and the normalization of the evaluation content. Besides an assessment tool, SMART provides treatment options. At present, the SMART treatment stage has been formalized, which can create personalized treatment plan for patients. The intervention after DOC evaluation can be divided into exploration, strengthening and education. SMART is advantaged in evaluation, treatment and prognosis, that can benefit the standardization of diagnosis and intervention of DOC in China.
