Patellofemoral contact pressures.
A test rig for studying the biomechanical behaviour of post-mortem human knees is built. For loading the quadriceps tendon a special clamping device is constructed, so the forces up to 3000 N could easily be transferred to the tendon. Several post-mortem human knees used in this study are tested to collect data about the general biomechanics of knee joint during squatting. The forces in the qua...
متن کاملContact pressures in the human hip joint.
The pressure distribution between the cartilaginous surfaces in the human hip joint was measured using pressure-sensitive film. Five cadaveric hip joints (aged between 58 and 87 years) were measured at three positions and loads, representing three instants in the stance phase of the walking cycle. The pressure distribution was not uniform, indicating that the cartilage did not, to any great ext...
متن کاملIntraglottal Contact Pressures in Human Voice Production
Some fundamental questions concerning voice production remain unanswered despite numerous research approaches in various fields of voice science. It is widely believed that high intraglottal pressures may cause organic voice disorders like vocal fold nodules or contact granulomas. This hypothesis seems reasonable but is difficult to prove given the challenges of pressure measurement and of es...
متن کاملPlantar pressures with total contact casting.
Total contact casting has been used to aid in the healing of plantar neurotrophic ulcerations. The efficacy of total contact casts in promoting ulcer healing is presumably due to a reduction in the load over high pressure areas with pressure redistribution over the entire surface of the foot. The purpose of this study was to quantify the effectiveness of total contact casting in reducing planta...
متن کاملInverse dynamics with rigid contact and friction
Inverse dynamics is used extensively in robotics and biomechanics applications. In manipulator and legged robots, it can form the basis of an effective nonlinear control strategy by providing a robot with both accurate positional tracking and active compliance. In biomechanics applications, inverse dynamics control can approximately determine the net torques applied at anatomical joints that co...
