Regardless of the high positive correlation between crosstalk and level of effort, the crosstalk...

.... Sixteen fresh-frozen human femurs and five artificial femurs were obtained. Cortical specimens were mounted into a clamping system equipped with a thrust force and torque transducer. Using a CNC machine, unicortical holes were drilled in each specimen at 1000 rpm, 1250 rpm, and 1500 rpm with a 3.2 mm...

... all hypothesized cost measures as a function of the chosen recovery strategy and the timing of the stumble during gait. Minimization of the cost measures based on the required torque, impulse, power and torque/time results in a humanlike strategy preference. The cost measure based on swing work does...

... retained at 100 s (44%), torsional stiffness ( 19.5 N mm ∕ deg ) , torque remaining at 100 seconds (66%), torque-to-failure (1253.9 N mm), and angle-to-failure ( 50.4 deg ) . Tests showed the following average values for reconstructed specimens: linear stiffness ( 5.4 N ∕ mm ) , linear load retained at 100...

...Raziel Riemer, Ph.D.; Elizabeth T. Hsiao-Wecksler, Ph.D. Two main sources of error in inverse dynamics based calculations of net joint torques are inaccuracies in segmental motions and estimates of anthropometric body segment parameters (BSPs). Methods for estimating BSP (i.e., segmental moment...

... knees. First, normal right and left pairs of knees from four New Zealand White (NZW) rabbits were subjected to cyclic loading. An extension torque of 0.2 Nm was applied to each knee. The average change in knee joint extension from the first to the fifth cycle was 1.9 deg ± 1.5 deg mean ± sd with a total...

...Hang-Shing Cheng; Ming-Shaung Ju; Chou-Ching K. Lin This paper develops an assistive torque system which uses homogenic surface electromyogram (EMG) signals to improve the elbow torque capability of stroke patients by applying an external time-varying assistive torque. In determining the magnitude...

... to reflect nominal age-related changes in muscle mechanics that have been reported in the literature. A second objective was to determine whether using the parametric adjustments resulted in simulated dynamic ankle torque behavior similar to that seen in healthy old adults. The primary parameter adjustment...

... and bone, allowing quantitative analysis of the micromotions and twisting of stem and bone, and the location of torque (force) transfer. Four types of prostheses were compared, which revealed striking differences in torque transfer. Our results for synthetic femurs are consistent with in vivo data...

...Alberto Doria; Roberto Lot This paper deals with the analysis of experimental data obtained using an ergometer apparatus. A straightforward analysis method based on the power equation and the concept of generalized torques is presented. This method makes it possible to study the influence...
