..., joint work was calculated by integrating joint power, which was calculated using inverse dynamics. Although this approach is commonly used, it is not without flaws. Joint work is an approximation of muscle–tendon work because it cannot take co-contraction of antagonistic muscles, biarticular muscle work...

... muscles to a pressurized air source. Since our treadmill was not instrumented with force platforms, we could not compare joint powers using inverse dynamics for unpowered and powered walking to rule out redistribution of mechanical power. However, recent results from our lab indicate no difference...

... versus without exoskeleton walking, to prevent any increases in metabolic cost due to added distal mass from affecting our results. The inverse dynamics analysis we carried out to assess lower limb joint powers also accounted for added exoskeleton mass and inertia, and should therefore reflect...

... and ankle. Muscle work was derived as the area under the joint power vs time curves and was partitioned into positive, negative and net components. Dependent t -tests were used to compare positive and negative work in level walking and net joint work between ascent and descent gaits on the ramp and stairs...

... locomotion hopping joint power inverse dynamics tammar wallaby Macropus eugenii. Terrestrial animals that move with a bouncing gait, such as running,trotting or hopping, take advantage of energy stored elastically in the limbs to reduce the metabolic cost of locomotion at steady speeds...
