Abstract Background The three-dimensional description of rigid body kinematics is a key step in many studies in biomechanics. There are several options for describing rigid body orientation including Cardan angles, Euler angles, and quaternions; the

Human foot rigidity is thought to provide a more effective lever with which to push against the ground. Tension of the plantar aponeurosis (PA) with increased metatarsophalangeal (MTP) joint dorsiflexion (i.e., the windlass mechanism) has been credit

Soft tissue moves relative to the underlying bone during locomotion. Research has shown that soft tissue motion has an effect on aspects of the dynamics of running; however, little is known about the effects of soft tissue motion on the joint kinetic

This study examined the effects of different amounts of heel pad confinement on the mechanical behaviour of the human heel pad. Confinement can be manipulated in two ways: containment defined as the act of heel pad confinement by an external device (

Cats have a remarkable ability to survive drops from great heights. This ability is examined by considering the aerodynamics of the cat during a drop, and by examining the mechanics of the landing. For the landing the spring-like properties of the ca
