Abstract

Unilateral spatial neglect (USN) is a higher brain dysfunction that frequently occurs due to right-hemisphere stroke. In this study, we compared conventional paper tests (i.e., line bisection test, line cancellation test, and design copying test) with the Behavioral inattention test (BIT) and the functional independence measure (FIM), which is an ADL test, in 24 patients with USN associated with right-hemisphere stroke to determine effective assessment methods in the clinical setting. To the extent that BIT worsened, conventional paper tests also declined, suggesting that BIT was correlated with conventional paper tests. Moreover, significant correlations were found between BIT and FIM, and FIM also declined in accordance with the worsening of conventional paper tests (line cancellation test and design copying test), indicating that conventional paper tests were also correlated with FIM. Nonetheless, BIT may impose physical, mental, and time burdens on the elderly, particularly in time-constrained clinical settings. Accordingly, the use of conventional paper tests as screening tests, followed by BIT as a deep test as appropriate, may increase the reliability of USN assessment in clinical settings.
