PURPOSE: This article examines the effectiveness of differentiated rehabilitation programmes for patients with two distinct types of hemispatial neglect: body-centred and object-focused. We hypothesized that patients with body-centred neglect would respond to motor-control programmes designed for patients with limb apraxia, while those with object-focused neglect would require visually oriented therapy.
MATERIAL AND METHODS: The article describes the rehabilitation of two patients treated by the authors 6-9 months after right-hemisphere infarct. Both showed significant left-sided hemispatial neglect: body-centred in one case (patient BC), object-focused in the other (patient OF). A modified AB-BA experimental design was used, where A represents visual training, and B is spatio-motor training. For patient BC, the sequence was A-B; for patient OF, B-A. Neglect was measured using standard tests for neglect and the analysis of drawings made during therapy by both patients.
RESULTS: As hypothesized, patient BC showed no progress after conclusion of programme A, while after programme B she showed virtually no lingering neglect. In the case of patient OF, the results were exactly reversed.
CONCLUSIONS: Body-centred neglect is essentially a defect in space formation, while object-focused neglect is a disorder of object formation. The patients described here both benefited from neuropsychological therapy for neglect, but not from the same programme.
