The purpose was to testify whether STMS assessment was adapted to the cognitive function assessment for the patients with brain injury. Methods The STMS assessment was used in the comparison of the brain injued patient in different stages and different injued cerebral hemisphere, and comparison between the patient and the normal person was then made. Results ①The score of the patient was increasing dramatically with the elapse of time(P<0. 05); ②Comparing the patients in the recovery period with the normal person, the whole score was not significantly different, but still had some difference in some of the subjeets(P<0. 05); ③There was significant difference in the score of STMS in the ability of comprehension and orientation, between the left and the right injuried cerebral hemisphere(P<0.05). Conclusion STMS is a useful assessment method. It can be used in the cognitive function in the brain injuried patient.
