Developing an instrument for the measurement of grip ability after distal radius fracture.

Background: Distal radius fracture (DRF) often causes reduced ability to perform activities of daily living (ADLs). There is a need for recurrent evaluation of the ability to perform ADL in the early stage of rehabilitation as a complement to traditional functional measures. Aim: Develop a short and simple performance test for use in clinical practice through modification of the Sollerman Grip Function Test (GFT). Method: DRF patients and controls performed the GFT. The tasks that discriminated patients from controls were calculated for sensitivity to change and correlated to the QuickDASH questionnaire at three subsequent occasions. Interrater reliability was tested. Results: Twelve GFT tasks discriminated DRF patients from healthy controls. One task was excluded due to heavy load. Remaining 11 tasks were all sensitive to change. Four tasks with correlation to the QuickDASH and representing the grip types most frequently used in ADL came to constitute the Wrist Performance Test (WPT). A test-retest showed satisfactory interrater reliability (rs = 0.87). Conclusion: A short performance test was developed through modification of the GFT. It is easy to use in clinical practice to evaluate the rehabilitation process after DRF. [ABSTRACT FROM AUTHOR]
