Thirty-five stroke patients were assessed on the Rivermead Perceptual Assessment Battery (RPAB) and three functional activities. The activities chosen had reported constructional components. A checklist was developed to measure a person's performance on the constructional components of each activity objectively. The RPAB results were correlated with those of making a sandwich and packing a lunchbox, putting on a cardigan and setting a table. A statistically significant relationship was found between the RPAB and the selected functional tasks. The results also suggest that a clinical relationship exists between performance on the RPAB and the three tasks, therefore assumptions can be made about a person's performance on these tasks using the results from the RPAB.
