A model for human postural balance is considered in which the time-delayed feedback
depends on position, velocity and acceleration (proportional–derivative–acceleration (PDA) …

The study investigated the effects of slackline training (rope balancing) on balance, jump
performance and muscle activity in children. Two primary-school classes (intervention, n …

Stick balancing on the fingertip is a complex voluntary motor task that requires the
stabilization of an unstable system. For seated expert stick balancers, the time delay is 0.23 …

This study proposes a generalization of the ankle and hip postural strategies to be applied to
the large class of skills that share the same basic challenge of defeating the destabilizing …

Slackline training (balancing on nylon ribbons) has been shown to improve neuromuscular
performance in children and adults. Comparable studies in seniors are lacking. Thus, 32 …

Low back pain (LBP) represents the most prevalent, problematic and painful of
musculoskeletal conditions that affects both the individual and society with health and …

The question of how the inverted position of a pendulum can be stabilized is of fundamental
importance for understanding human balancing tasks. Applications range from postural …

Psychological “flow” emerges from a goal requiring action, and a match between skills and
challenge. Using high-density electroencephalographic (EEG) recording, we quantified the …

We present stability and control analysis of a rider-bicycle system under human steering and
body movements. The dynamic model of rider-bicycle interactions is first constructed to …

A nonlinear model for human balancing subjected to a saturated delayed proportional–
derivative–acceleration (PDA) feedback is analysed. Compared to the proportional …
