Background. Previous research has demonstrated that control cognitions predict functional limitations following stroke. This paper reports a preliminary evaluation of the effects of a workbook intervention, designed to enhance perceptions of control, in reducing disability in patients discharged from hospital following stroke. Methods. Thirty‐nine patients living at home who had had a stroke within the 2 previous years completed baseline assessments of functional limitations, mood and perceived control. They were then randomly allocated to either a Workbook Intervention or a Wait control group and functional limitation and mood outcomes were assessed 1 month later. Results. Results showed no benefit of the intervention, but both groups showed reduced functional limitations. Reductions in functional limitations were correlated with increases in perceptions of control. Conclusions. Clearly, the workbook intervention needs to be strengthened before a full evaluation would be worthwhile for this clinical group. It is possible that both groups demonstrated spontaneous recovery or may have benefited from the additional attention given by the researcher. These benefits were associated with enhanced perceptions of control, contributing to previous findings suggesting that control cognitions may be both a consequence and a determinant of functional limitations.

This paper presents a critical appraisal of the MUSS portable operating system. Development costs for the system are discussed, including the cost of transferring it to a new machine. Its performance is also examined, together with a description of the techniques used to assess performance.
