Introduction
Hemispatial neglect is defined by the inability of a person to process and perceive stimuli on one side of the body or environment. It is closely related to the deterioration of cognitive function. The line bisection test (LBT) is most commonly performed to confirm hemispatial neglect and the results within 5 minutes are considered. Although the time to complete the test is closely related to the cognitive function, there is no study considering time concept. In this study, we measured the time of LBT and tried to confirm the relationship with cognitive function through Mini-Mental State Examination (MMSE).
Materials and Methods
Thirty patients who were admitted to the rehabilitation department with brain injury were enrolled from September 2017 to February 2018. The patients were included 1) ischemic/hemorrhagic stroke and brain tumor, 2) subacute stroke (onset < 6 months), and 3) more than 1 step verbal command obey. LBT and MMSE were performed at the time of admission, and one month later. The time to complete the LBT was also measured. The correlation between LBT time change and MMSE score change was confirmed by Pearson correlation coefficient.
Results
The demographic factor of the patient was as shown in Table 1. Comparing LBT time change and the MMSE subscale score change, the total score (r = 0.374, p = 0.042) and the recall domain (r = 0.374, p = 0.042) showed a positive correlation (Table 2).
Conclusion
LBT and MMSE are one of the most commonly used testing tools for patients with brain injury. A significant correlation between LBT time change and the total score and the recall subscale score change in MMSE is considered to be related to attention. Measuring time when performing LBT is simple and can be used as a tool to predict the prognosis of cognitive function related to attention. Further study with larger sample size and follow up study is necessary. |
