Pathologiessuch as stroke or cerebral palsy are often characterized by excessivemediolateral bending of the trunk. However, it is unclear how mediolateral trunk-sway affects mechanicalwork of more distal joints during gait. We therefore pose the researchquestion: How does increased mediolateraltrunk-sway affect the total system work and that of dis...
À partir de la clinique rencontrée en chirurgie pédiatrique, les auteures proposent d’interroger les enjeux du désir, de la construction identitaire féminine, de la filiation et la fécondité complexe du travail conjoint psychologue-chirurgien.ne. Deux cas cliniques d’adolescentes présentant une excroissance génitale (nymphomégalie pour l’une et mas...
A typical gait pattern of a healthy individual is characterized by coordinated kinematics of body segments that minimize the energy cost of transport. This is achieved by a well-coordinated sequence of energy generation, transmission, and absorption by muscles. Knowing the energy exchange between the body segments can explain the mechanisms that go...

Summary: Biofeedback based on real-time inverse dynamics reveals that ankle power generation during walking influences workload placed on more proximal leg muscles, trailing leg mechanical output and step length.

Surprisingly little information exists of the mechanics in the steps initializing the walk-to-run transition (WRT) in humans. Here, we assess how mechanical work of the limbs (vertical and horizontal) and the individual joints (ankle, knee and hip) are modulated as humans transition from a preferred constant walking velocity (vwalk) to a variety of...

PurposeOld compared with young adults walk with reduced ankle and increased hip mechanical output. We examined the idea that age, leg strength, or both are related to the age-related changes in mechanical output during gait.MethodsHealthy young (n = 32, age 21.5 years) and old adults (n = 32, age 76.8 years) participated in biomechanical gait analy...

Measuring biomechanical work performed by humans and other animals is critical for understanding muscle-tendon function, joint-specific contributions and energy-saving mechanisms during locomotion. Inverse dynamics is often employed to estimate joint-level contributions, and deformable body estimates can be used to study work performed by the foot....
