Proportion of physical activity level distribution per disability (EDSS) group (distribution of π).
| EDSS group [N] | Disability level | Low π1 (SD) | Moderate π2 (SD) | High π3 (SD) |
|---|---|---|---|---|
| 0.0–3.5 [36] | No “walking” disability | 0.47 (0.07) | 0.37 (0.04) | 0.15 (0.06) |
| 4.0–5.5 [26] | Walking disability present | 0.51 (0.05) | 0.36 (0.03) | 0.13 (0.05) |
| 6.0 [18] | Needs a cane to ambulate | 0.55 (0.05) | 0.34 (0.04) | 0.11 (0.04) |
| 6.5 [14] | Needs 2 canes or a walker to ambulate | 0.61 (0.06) | 0.31 (0.07) | 0.09 (0.03) |
Each participant was fit individually, and the proportion of physical activity was extracted for the group distribution. The greater the level of disability (i.e. EDSS = 6.5) the higher proportion of lower levels of physical activity (π1) recorded, and the lower disability (i.e. EDSS = 0.0–3.5) the greater proportion of moderate (π2) and high physical activity (π3) levels recorded (Kruskal-Wallis Test: p = 0.0001).
EDSS, Expanded Disability Status Score; N, sample size in each group; SD, standard deviation; μ1, mean steps - low physical activity; μ2, mean steps - moderate physical activity; μ3, mean steps - “high” (relatively) physical activity, Low variance, σ1; moderate variance, σ2 and high variance, σ3, π1, Low proportion of physical activity; π2, moderate proportion of physical activity; π3, high proportion of physical activity.
