2. The original WISCI incorporated 20 levels, including increasing levels of physical assistance and devices (arm devices for using parallel bars, walkers, crutches and canes as well as leg braces) required for walking. Level 0 was “patient is unable to stand and/or participate in walking” to level 19 “ambulates with no devices, no braces and physical assistance, 10m”.
3. The WISCI II contains an additional item “ambulates with no devices, with brace and no assistance”.
4. Ten meter distance selected as it represents household ambulation and it represents the international metric.
2. Unlike other tests such as the Timed Up and Go, the WISCI II scoring includes the type of assistance or device required.
3. A score is possible even if the individual cannot walk 10 m.
4. The hierarchical ranking of the WISCI II scale has been validated by demonstration of monotonic progression of walking capacity.
2. Because the furthest walk distance is 10m, it would not be suitable for individuals with minor impairments. In one study, 17% (42/249) of individuals had a score of 20 (i.e. ceiling effect).
3. Comparisons with timed tests (e.g. 6 Minute Walk Test, 10 Meter Walk Test) indicated that the WISCI II is not as responsive.
4. Walking speed data would improve responsiveness and decrease the ceiling effect.
Interpretability – No normative data or cut scores are available but the WISCI II is gaining popularity and comparisons can be made with existing studies. Scores are self-evident.
Acceptability – The WISCI levels are relevant to individuals with SCI. There is no additional burden is as the test falls into typical clinical practice parameters.
Feasibility – Equipment required is typically available in the clinical setting and includes: 5 meter parallel bars and walking devices (e.g. braces, cane, walker). Administration time is client dependent. Special training beyond knowledge of ambulation is not required. Scoring definitions provided are clear. Information regarding specific instructions (e.g. practice attempts) is lacking.
