Design of Biomechanical Legs with a Passive Toe Joint for Enhanced Human-like Walking

The Journal of Engineering Research, 2017
This paper presents the design procedure of a biomechanical leg, with a passive toe joint, which is capable of mimicking the human walking. This leg has to provide the major features of human gait in the motion trajectories of the hip, knee, ankle, and ...

Biallelic PIGB Variants Cause Motor Neuropathy with Conduction Blocks and Peripheral Nerve Hyperexcitability

Annals of Neurology, EarlyView.
Objective Glycosylphosphatidylinositol (GPI)‐anchored proteins play critical roles in nervous system function. Pathogenic variants in genes involved in GPI‐anchor biosynthesis cause early‐onset multisystem disorders known as inherited GPI deficiencies. We describe a novel neuromuscular phenotype associated with PIGB deficiency.

Examining lower leg biomechanics during toe-in and toe-out walking in people with medial compartment knee osteoarthritis

, 2017
Introduction: Knee osteoarthritis is a common and painful disease, and is one of the leading causes of disability in Canada. It is thought that one of the primary causes of disease progression is excessive knee joint loading.

Evolutionary morphology of the haplorhine hamate

The Anatomical Record, EarlyView.
Abstract Primates adopt a variety of hand postures during an impressive diversity of locomotor and manipulative behaviors. Morphological research has found that elements of the hand skeleton, such as the hamate, hold key information for inferring hand use and locomotor kinematics in extinct species.

The pelvis doesn't walk by itself: Wider pelves reduce the cost of walking over unstable surfaces

The Anatomical Record, EarlyView.
Abstract Walking over variable and/or unstable terrain is a key aspect of daily life and was crucial to the evolution of bipedalism. The ability to find gait solutions that maintained stability over uneven terrain for the least increase in metabolic cost was likely a hallmark of locomotor effectiveness in early humans, in particular acting as an ...

Foot loading is different in people with and without pincer nails: a case control study

Journal of Foot and Ankle Research, 2015
Background Recent studies suggest that pincer nails are caused by lack of upward mechanical forces on the toe pad. However, clinically significant pincer nails are also often observed among healthy walkers.

Endoscopic Plantar Partial Sesamoidectomy for the Management of Metatarsalgia of the First Metatarsal Head After Arthrodesis of the First Metatarsophalangeal Joint

Arthroscopy Techniques, EarlyView.
Abstract First metatarsophalangeal arthrodesis has been used to treat various pathologies of the great toe with good clinical outcome. First metatarsal head metatarsalgia can occur after first metatarsophalangeal arthrodesis. Surgery is indicated if conservative measures cannot alleviate the symptoms.

Locked in Transition: Examining the Role of Paradoxical Tensions in the Transition From Industrial Cluster to Eco‐Clusters

Business Strategy and the Environment, EarlyView.
ABSTRACT Industrial clusters are central to the circular economy transition, yet how they develop into eco‐clusters and the paradoxical tensions this transformation fuels remain underexplored. Drawing on 48 in‐depth interviews and secondary data from a Turkish textile‐recycling cluster, we develop an empirically grounded model of eco‐cluster transition

Toe-In and Toe-Out Walking Patterns and Lateral Wedge Insoles: A Musculoskeletal Simulation and Probabilistic Modelling Assessment of Medial Tibiofemoral Cartilage Mechanics

Life
This study examined lateral wedge insoles and altered foot progression angles on medial tibiofemoral loading and long-term cartilage failure risk. Fifteen healthy male participants walked under four conditions: neutral gait, lateral wedge insoles, toe-in

A multifaceted behavioural approach to correcting ideopathic toe-walking in children with autism: A pilot project

, 2013
Toe walking is a toe-to-toe movement pattern that for a brief period of time, is a typical phase of learning how to walk in a mature heel-to-toe pattern.
