A higher-derivative model predicts a smoothness vs duration relationship in head-pointing movements
N. Boulanger, F. Buisseret, J. Burny +4
Head movements require integration of visual, proprioceptive, vestibular, and cervical motor signals. The dynamical principles governing their temporal organization remain unclear.…
From Brain to Motion: Harnessing Higher-Derivative Mechanics for Neural Control
O. White, F. Buisseret, F. Dierick +1
Optimal Feedback Control (OFC) provides a theoretical framework for goal-directed movements, where the nervous system adjusts actions based on sensory feedback. In OFC, the central…
The two-thirds power law derived from an higher-derivative action
N. Boulanger, F. Buisseret, F. Dierick +1
The two-thirds power law is a link between angular speed and curvature observed in voluntary human movements: is proportional to . Squared jerk is known to be…
Diffusion in Phase Space as a Tool to Assess Variability of Vertical Centre-of-Mass Motion During Long-Range Walking
N. Boulanger, F. Buisseret, V. Dehouck +2
When a Hamiltonian system undergoes a stochastic, time-dependent anharmonic perturbation, the values of its adiabatic invariants as a function of time follow a distribution whose s…
Motor strategies and adiabatic invariants: The case of rhythmic motion in parabolic flights
N. Boulanger, F. Buisseret, V. Dehouck +2
The role of gravity in human motor control is at the same time obvious and difficult to isolate. It can be assessed by performing experiments in variable gravity. We propose that a…
Adiabatic invariants drive rhythmic human motion in variable gravity
N. Boulanger, F. Buisseret, V. Dehouck +2
Natural human movements are stereotyped. They minimise cost functions that include energy, a natural candidate from mechanical and physiological points of view. In time-changing en…
Higher-derivative harmonic oscillators: stability of classical dynamics and adiabatic invariants
Nicolas Boulanger, Fabien Buisseret, Frédéric Dierick +1
The status of classical stability in higher-derivative systems is still subject to discussions. In this note, we argue that, contrary to general belief, many higher-derivative syst…
Ergonomic risk assessment of developing musculoskeletal disorders in workers with the Microsoft Kinect: TRACK TMS
F. Buisseret, F. Dierick, O. Hamzaoui +1
Routine ergonomic assessment of postures and gestures in the workplace are mostly conducted by visual observations, either direct or based on video recordings. Nowadays, low-cost t…
Fractal Analyses Reveal Independent Complexity and Predictability of Gait
F. Dierick, A. -L. Nivard, O. White +1
Locomotion is a natural task that has been assessed since decades and used as a proxy to highlight impairments of various origins. Most studies adopted classical linear analyses of…
Unstable Footwear as a Speed-Dependent Noise-Based Training Gear to Exercise Inverted Pendulum Motion During Walking
F. Dierick, A. -F. Bouche, M. Scohier +2
Previous research on unstable footwear has suggested that it may induce plantar mechanical noise during walking. The purpose of this study was to explore whether unstable footwear…
