TABLE 4.

Estimated gait parameters of young and elderly test subjects (n = 20 each) in real-world and lab environment (mean ± standard deviation) clustered in A, B and C.

Absolute (abs diff) and mean relative differences (mean rel diff) between the non-controlled real-world and controlled lab environments are presented. P-values are calculated based on the abs diff data, resulting values smaller than 0.05 are considered statistically significant (marked in green). Respective abbreviations are listed in Table 2. *Skew distributed data, transformed logarithmically for p-value calculation (Wilcoxon signed-rank test requires symmetric data distribution). **(A) Significant differences between the two environments for both groups; (B) Significant differences between the two environments for elderly group only; (C) Remaining differences.
