Figure 4

Minimum, first quartile (q1), median, third quartile (q3) and maximum values of mean absolute errors (mae) relative to: (a) IC, (b) step time and (c) stride length for all groups (healthy elderly – E, hemiparetic – H, Parkinson’s disease – P and choreic – C). Errors larger than q1 + 1.5(q3 + q1) or smaller than q1–1.5(q3–q1) are considered outliers and represented with red marks (+).
