BACKGROUND In all studies in which the strength of the neck extensor muscles has been measured, the level of thoracic support has been adjusted differently so direct comparison of the results is not possible. OBJECTIVE To measure and compare the isometric force and isometric torque of neck extensor muscles at different levels of thoracic support. (More)
It is well known that any balance control disturbance can increase the risk of injury during sport activities. Knee deformities such as genu valgum and genu varum may perturb the line of gravity passing the lower limb joints and so disturb dynamic and static balance indices. This study was designed to investigate the effects of genu valgum and genu varum(More)

The proven natural gas reserves in the world exceeds 6000 Trillion Cubic Feet (TCF), from which about 50% is located in remote areas with no economic feasibility to be produced, shipped and sold. Approximately half of the stranded gas reserves are located off-shore. This implies the necessity to find solutions for utilization of most of the undiscovered(More)
This work extends the probabilistic roadmap (PRM) framework by efficiently incorporating the force closure (FC) criterion into motion planning. A new FC verification approach is proposed that eliminates the need for testing FC in the intermediate configurations of the local planner. The algorithm is tested for special kinds of planar robots that have two(More)
