Is visual scanning better than mental practice in hemispatial neglect? Results from a pilot study.

AbstractOBJECTIVE:
We compared visual scanning and mental practice and explored the effects of these techniques on specific hemispatial neglect tests and activities of daily living in chronic hemispatial neglect patients.
METHODS:
Ten right-handed patients with hemispatial neglect caused by right hemisphere ischemic strokes were randomly allocated to 1 of 2 study groups: visual scanning (n = 5), mental practice (n = 5). Five additional patients were included in a control group. Three evaluations for hemispatial neglect and the FIM were carried out in the intervention groups: pretreatment, at the end of the intervention period, and 3 months after that intervention period. Control patients were evaluated twice within a 2-month interval.
RESULTS:
There was a significant difference among the 3 groups in Behavioral Inattention Test (BIT) score changes (P = .047) and in FIM self-care item score changes (P = .035), the visual scanning protocol being responsible for these differences both in BIT (P = .008) and in FIM self-care item scores (P = .016). The positive functional effects of visual scanning were partially retained at the end of the follow-up period.
CONCLUSIONS:
Visual scanning should probably be considered preferable to mental practice protocols in the treatment of hemispatial neglect patients.
