Lemmens RJM et al. – Although many instruments assess capacity and perceived performance, a dearth exists of instruments assessing actual performance. In addition, instruments appropriate for more than one patient population are sparse. For actual performance, new instruments have to be developed, with specific focus on the usability in different patient populations and the assessment of quality of use as well as amount of use. Also, consensus about the choice and use of instruments within and across populations is needed.Methods
- A systematic literature search was performed to identify articles containing instruments assessing arm-hand skilled performance in patients with stroke or cerebral palsy.
- Instruments were identified and divided into the categories capacity, perceived performance and actual performance.
- A second search was performed to obtain information on their content and psychometrics.
- Regarding capacity, perceived performance and actual performance, 18, 9 and 3 instruments were included respectively.
- Only 3 of all included instruments were used and tested in both patient populations.
- The content of the instruments differed widely regarding the ICF levels measured, assessment of the amount of use versus the quality of use, the inclusion of unimanual and/or bimanual tasks and the inclusion of basic and/or extended tasks.
