Differences in postural strategies between children with and without ADHD in tasks of static and dynamic balance [PDF]
Frontiers in Human NeuroscienceBackgroundMany children with ADHD experience challenges with balance and postural control, unlike their unaffected peers. While postural sway has been extensively studied in this patient group, less is known about the postural strategies employed to ...

Self-weight Balance Design of Portal Crane Boom [PDF]
E3S Web of Conferences, 2021 During the luffing of the portal crane, the height changing of the center of gravity of the boom needs to consume extra energy, which not only wastes energy, but also makes the luffing drive system need to use a larger motor.

Kinematic and Dynamic Simulation Analysis of Modified Conventional Beam Pumping Unit
Energies, 2022 The large net torque fluctuations in the reducer output shafts of conventional beam pumping units and the existence of negative torque are the decisive factors that lead to their low efficiency and high energy consumption. This study developed a positive

Design of Torque Balancing Mechanisms [PDF]
Journal of Mechanics Engineering and Automation, 2017 Machines are often subjected to periodic loads, related both to the characteristics of the payload or to the kinematic chains used for motion generation, such as linkages or cam follower mechanisms. The load fluctuation can cause several inconveniences to the proper functioning of the machines, like shaking forces and moments, vibrations, severe speed

The role of torque feedback in standing balance
Journal of Neurophysiology, 2023 Using model simulations and a novel experimental approach, we tested behavioral predictions of a sensory torque feedback mechanism involved in the control of upright standing. Torque feedback is thought to reduce the effort required to stand and play a functional role in slowly aligning the body with gravity.
