Abstract:
In patients suffering from left unilateral neglect, their right-biased attention to
the phenomenal world can be ameliorated, short-term, by making motor responses to
left-right extended objects (rods) that immediately reveal to them that their
phenomenal world is in fact skewed. In this study the extent to which more intensive
experiences of this type produced enduring and useful improvements in neglect, was
assessed by first examining the effect of a 3 day experimenter-administered practice
of rod lifting, then by examining the effects of a self-administered practice for a
further 2 week period and a further one month post-training. Despite the fact that by
the time the patients were able to undergo the intervention they had progressed to the
chronic neglect stage, significant improvements of the intervention over the control
group were found for a third of the tests given after the three day practice.
Additionally, at the one month follow-up the intervention group again showed
significantly better results in 46% of the direct neglect tests. As far as we are aware
this is the first time that significant long?term improvements have been shown in a
rehabilitation approach with neglect patients with a mean time of more than 12
months post stroke and visuomotor feedback training can thus be seen as a most
encouraging paradigm for future attempts.
