| Popis: | Both proprioceptive and visual manipulations have led to some improvement of the spatial neglect syndrome. Until now, their effects on visuo-spatial behaviour have never been compared simultaneously. The objective of this study was to determine their influence, as a function of the presence of neglect and the side of the brain damage. 19 stroke patients with right and 14 with left brain damage, without or with neglect; realized the Bells test in 5 conditions: a reference condition and 4 sensory conditions, defined according to the side of application (contralesional vs ipsilesional) and the type of perturbation (visual vs proprioceptive). The visuo-spatial behaviour was analyzed for global and spatial aspects and for individual extreme performances. For the neglect group, the restriction of the visual field to the ipsilesional hemi-field significantly diverted the centre of exploration towards the ipsilesional side compared to all other conditions. The weighting of visual cues from the ipsilesional hemi-field seems to be increased in sensory-motor integration processes in neglect patients. In all the groups, although some improvements in performance did occur with sensory manipulation, they were dependent on the individual, particularly for neglect patients. A same performance can be achieved through the use of different sensory-motor strategies, which are individual-related. It is thus important to consider the sensory sensitivity and the responsiveness of each patient before beginning any sensory therapies. |
