From: The impact of PCA derived gait kinematic variations on estimated medial knee contact forces in a knee osteoarthritis population

Fig. 7

Functionally relevant changes as result of kinematic variations in first (top) and second peak (bottom) medial compartment knee contact forces (KCF) expressed as a % difference in body weight (BW) compared to knee contact forces estimated using the mean gait pattern. Each colored bubble represents a different joint degree of freedom and its dimension denotes its contribution (%) to the kinematic variation of the mode with ± 1 STD (HS: healthy in blue label; KOA: knee OA in red label). The “+” and “−“ signs next to the mode numbers denote the direction of the STD. Only joints contributing to the top 50% are displayed as illustrated in Fig. 4.
