説明
The primate hand adopts a variety of postures during locomotion. Habitually terrestrial cercopithecine primates are known to use a palmigrade posture at faster speeds to possibly mitigate stresses on the hand skeleton; however, it is unclear whether arboreal or semi-terrestrial species use a similar strategy for adjusting hand posture. Here, we explored intra-individual variation in hand contact patterns during terrestrial locomotion in the Japanese macaque (Macaca fuscata), a semi-terrestrial cercopithecine primate. Two monkeys were required to walk on the ground at their own preferred speeds or were encouraged to move faster for food rewards. The contact area under the hand and ground reaction forces (GRFs) were measured simultaneously using a tactile pressure sensor, and then hand pressures were calculated offline. We found that hand contact patterns could vary within individuals. The monkeys used predominantly a palmigrade posture within the range of speeds covered in this study (0.72-2.56 m s
