Abstract
Norm scores of cancelation and bisection tests for unilateral spatial neglect: data from a Brazilian population
Highlights
Unilateral spatial neglect (USN) results in a consistent and exaggerated spatial asymmetry in the processing of information about the body or space due to an acquired brain injury that cannot be accounted for by either sensory or motor deficits [1,2,3,4]
The cutoff points presented in this study may be indicative of USN, but due to performance differences based on age, we suggest using different norm scores for different age groups
We evaluated and screened 250 individuals, but only 150 met the inclusion criteria for the study
Summary
Unilateral spatial neglect (USN) results in a consistent and exaggerated spatial asymmetry in the processing of information about the body or space due to an acquired brain injury that cannot be accounted for by either sensory or motor deficits [1,2,3,4]. Received for publication on September 18, 2019. Accepted for publication on February 7, 2020. USN is commonly assessed in the clinic using either the line bisection (LB) task or the target cancelation task [11]. USN tests were first proposed by Albert in 1973 [12]. During these tests, the patient is asked to find and cancel random lines on a sheet of paper. The patient is asked to find and cancel random lines on a sheet of paper This is the line cancelation (LC) task, and it is sensitive to spatial asymmetry in the processing of information about the body or space [13]
