Figure 2. Median peak loads.

Median Peak values of Fres (A), Mtors (B), and Mbend(C) and their ranges for the reference activities Level Walking (LW) with full ( = 100%) and half ( = 50%) weight bearing as well as the 13 physiotherapeutic exercises. Horizontal lines mark the activity-specific median peak value from walking. See Table 1 for exercise numbers descriptions. Walking at 100% level (with full weight bearing) and 50% level serve as reference for comparison. The numbers in the upper triangles indicate the number of patients having high loads, the number in the triangles below indicate the number of patient, in which medium loads were found.
