Achtergrond van het onderzoek
About 30% of all stroke patients admitted in a rehabilitation centre show unilateral visuospatial neglect. This disorder is characterized by the inability to respond to sensory stimuli in the affected (left) hemispace, due to damage to the right hemisphere. Visual scanning therapy, a training aimed at provoking eye movements to the affected hemifield, is often applied to attenuate neglect. Recent views on the attentional and motor system suggest new approaches to treat neglect. Congruence between different effectors of the motor system may produce a powerful bias in the motor system, which can counteract pathological biases in the attentional system. Therefore, an intervention with congruent eye and hand movements may result in greater attenuation of neglect symptoms compared to an intervention with single eye movements (as applied in visual scanning therapy).

Onderzoeksopzet
T0 = baseline measurement
T1 = measurement after all training sessions
Onderzoeksproduct en/of interventie
15 neglect patients will receive visual scanning therapy
15 neglect patients will receive a visual scanning training combined with congruent hand movements
Outcome measures for each training group will be compared to 15 stroke patients without neglected and 15 age matched healthy controls

Wetenschappelijk
Belangrijkste voorwaarden om deel te mogen nemen (Inclusiecriteria)
• Clinical diagnosed symptomatic stroke (ischemic or intracerebral haemorrhagic lesion), first or
recurrent, if possible verified by Magnetic Resonance Imaging (MRI) and/or Computed Tomography
(CT) data
• Signs of neglect:
o asymmetry between the left and right side of the stimulus field in number of missed items of at
least 2 on a shape cancelation task, and/or
o a bias towards the left or right side of space on a line bisection task, and/or
o Catherine Bergego Scale score higher than 6.
• 18-85 years of age
• Sufficient ability to comprehend and to communicate, as observed during neuropsychological assessment and/or neglect screening
• Sufficient motivation to participate in a daily rehabilitation treatment programme for two weeks.
• Written informed consent
Belangrijkste redenen om niet deel te kunnen nemen (Exclusiecriteria)
Patients who recovered from neglect between inclusion and start of the training (i.e. no signs of neglect anymore on all baseline measurements) will be excluded
