Ineffectiveness of prism adaptation on spatial neglect signs.
OBJECTIVE
To evaluate the effect of prism adaptation (PA) on spatial neglect signs.


METHODS
Ten patients (hemianopia in 6) and 8 control subjects were included. Tasks were reading single words, nonwords, and a text, bell cancellation, line bisection, and scene drawing, before and after adaptation, with either deviating or neutral prisms.


RESULTS
Errors were more frequent in patients but without any specific effect of PA. We found partial improvement at the late sessions, independent of prisms.


CONCLUSIONS
We did not confirm the efficacy of PA on spatial neglect.
