beroerte CVA stroke
Conditions
Interventions
The training exists of the presentation of elementary visual stimuli in a wide
border-area between the intact and defect visual field. The stimuli are white
dots, circling clockwise or counter clock

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Humphrey and Goldmann perimetry (subjective enlargement of the visual field). De Humphrey is an automated perimeter. The Goldmann perimeter is an original that is converted into an automatic perimeter, leading to both perimetry methods being unbiased. Humphrey provides static perimetry: defect-depths measured in relatively low resolution. Goldmann provides dynamic perimetry: measures the border between 'non-responsive' and 'responsive' fields in higher resolution. De effects of training vs non-training are deduced from the differences between improvement in trained areas vs de improvement in non-trained areas. | — |
Secondary
| Measure | Time frame |
|---|---|
| 2. reading test (reading speed) 3. Goal Attainment Scaling. This concerns the degree in which previously determined goals are reached during/after training. This in rehabilitation regularly used assessment method means that goals are identified, which are - specific (unambiguous goal) - measurable - acceptable or relevant to the patient - realistic/attainable | — |
