We propose the time-dependent generalization of an ‘ordinary’ autonomous human biomechanics, in which total mechanical + biochemical energy is not conserved. We introduce a general framework for time-dependent biomechanics in terms of jet manifolds derived from the extended musculo-skeletal configuration manifold. The corresponding Riemannian geometrical evolution follows the Ricci flow diffusi...

Animal locomotion arises from complex interactions among sensory systems, processing of sensory information into patterns of motor output, the musculo-skeletal dynamics that follow motor stimulation, and the interaction of appendages and body parts with the environment. These processes conspire to produce motions and forces that permit stunning manoeuvres with important ecological and evolution...

A one year prospective study of equestrian injuries was carried out in an area where horse riding is a popular pursuit. 115 persons suffered injury--eighty females and thirty-five males of whom sixty were under fifteen years of age. No fatalities were recorded and there were 0.2 injuries per 100 rides. Most injuries were minor and to the musculo-skeletal system. Visceral and cerebral injuries w...

Simulation of dynamic motion of soft tissues is one of the most important topic in nowadays computer animation of human body. So far various elastically deformable models were used for this purpose. We present the extension of model proposed in [15] with volume preserving constraint. We provide also evaluation of the constraint accuracy on two simulation experiments. Furthermore we add model of...

Fatal atlanto-axial dislocation occurred in two patients with rheumatoid arthritis and in both there were severe degenerative changes in the spinal ligaments and skeletal muscle in this area. Attention is called to the frequency of spontaneous cervical dislocations in rheumatoid patients and the advisability of obtaining routine radiographic examination of the cervical spine in patients with ad...

extension was almost full. Active flexion was improving and there was definite contraction of the biceps. By 21st November, 1961, there was full recovery of elbow movement and of muscle power, and he was discharged. SUMMARY. (1) A case of rupture of the tendon of the biceps brachii at the lower musculo tendinous junction is described. (2) Full functional recovery was obtained, although operativ...
