The wheelchair skills test (version 2.4): measurement properties1 R.Lee Kirby, MD, Debbie J Dupuis, PhD, Angela H MacPhee, MSc, Anna L Coolen, MSc, Cher Smith, BSc, Krista L Best, BSc, Allison M Newton, BSc, Anita D Mountain, BSc, Donald A MacLeod, MSc, James P Bonaparte, MSc Archives of Physical Medicine and Rehabilitation Volume 85, Issue 5, Pages 794-804 (May 2004) DOI: 10.1016/j.apmr.2003.07.007

Fig 1 Sample report form for the WST (version 2.4). The wheelchair user whose performance is shown was a 63-year-old man with a unilateral transfemoral amputation. Archives of Physical Medicine and Rehabilitation 2004 85, 794-804DOI: (10.1016/j.apmr.2003.07.007)

Fig 2 Reliability of the WST (version 2.4) (n=20). In each figure, the total WST percentage scores are plotted and the unity line is shown. (A) For test-retest reliability, wheelchair users’ scores on WSTs 1 and 2 are shown. (B) For intrarater reliability, the scores from 2 evaluations by the same rater are shown. (C) For interrater reliability, the scores from the evaluations of 2 different raters are shown. Archives of Physical Medicine and Rehabilitation 2004 85, 794-804DOI: (10.1016/j.apmr.2003.07.007)

Fig 3 Mean +1 SD total WST 2.4 scores, by diagnostic category, from lowest to highest. Archives of Physical Medicine and Rehabilitation 2004 85, 794-804DOI: (10.1016/j.apmr.2003.07.007)

Fig 4 Asymmetry indices, by diagnostic category. The medians are represented by the lines. The upper limit of the box represents the 75% quartile (ie, 75% of the values are smaller than that amount) and the lower limit represents the 25% quartile. The whiskers extend to the most extreme data point which is no more than 1.5 (interquartile range). The dots represent what are considered to be outliers, given the other measurements within a class.
