The Wheelchair Skills Program (WSP) is an integrated system that includes elements for testing and training wheelchair users, clinicians and/or their caregivers. The WSP was, until recently, only available in English. The goal of this study is to evaluate the inter-rater and test-retest reliability of the French-Canadian version of the Wheelchair Skill Test (WST-F), a component of the WSP. Nine participants were evaluated twice with the WST-F, at T0 by 1 rater and at T1 by 2 raters, with 3-12 days between T0 and T1. The mean (±1SD) Total Percentage Score for the WST- F was 77.5±14.5% at T0 and 77.7±14.1% at T1. For the inter-rater and test-retest reliability, the ICCs for the Total Percentage Scores were 0.997 (95% IC: 0.989-0.999), and 0.984 (95% IC: 0.937-0.996). Our preliminary findings suggest that the WST-F has excellent inter-rater and test-retest reliability.

Disney produced a television show in the mid 1990s called Gargoyles. It's a great show and I'm a big fan. A few years ago Disney started to release the show on DVD. The last release was of season 2, volume 1. That was two years ago. Volume 2 has not been released. Why? Poor sales. So if you should find yourself wanting to support my work, instead I ask you pick up a copy of season 2, volume 1. It's a great show and you might find yourself enjoying it.
