Fig. 4. Angular values for the lower limb joints of humans walking normally and
compliantly compared with bipedal walking gaits of the gibbon (Hylobates
lar) and the pygmy chimpanzee (Pan paniscus). The data for the
humans were collected at SUNY Stony Brook using the same sample as was used
for the maximum walking speed and stride length data presented in
Table 2. The data for the
gibbon are a composite of data from Prost
(1967) and Yamazaki and
Ishida (1984). The data for
the chimpanzee are from D'Aout et al.
(2002).
