Abstract

Background and purpose

Manual wheelchair users have a potential risk for musculoskeletal overuse
injuries. To prevent these overuse injuries wheelchair users need to be taught how to propel a wheelchair efficiently. To test how a person is manoeuvring the wheelchair the Drivkraft Wheelchair Manoeuvre Test (DWMT) was developed. The aim of this study is to determine the reliability components of the DWMT.

Method

The inter- intra-rater and test-retest reliability were determined for the four tasks of the DWMT. Three raters scored the test for the inter- and intra-rater reliability and one rater scored both the test and the retest in a different group of participants. Intraclass correlation coefficients (ICC) and kappa values were calculated.

Results

30 participants were included for the inter- and intra-rater reliability and 18 were included for the test-retest reliability. The inter-rater reliability showed ICC values that were good to excellent and the kappa was found to be strong to almost perfect. The intra-rater reliability values are excellent for all raters. Test-retest reliability showed perfect kappa values and excellent ICC values.

Conclusion

The DWMT has good to excellent inter- intra-rater and test-retest reliability when
sufficient sample sizes are used. Further research can be conducted using the DWMT.
