Toe walking is a gait deviation with multiple etiologies and often associated with premature and prolonged ankle plantar flexor electromyographic activity. The goal of this study was to use a detailed musculoskeletal model and forward dynamical simulations that emulate able-bodied toe and heel-toe walking to understand why, despite an increase in muscle activity in the ankle plantar flexors dur...

This paper presents the meta-algorithmic approach used to realize multi-contact walking on the humanoid robot, DURUS. This systematic methodology begins by decomposing human walking into a sequence of distinct events (e.g. heel-strike, toe-strike, and toe push-off). These events are converted into an alternating sequence of domains and guards, resulting in a hybrid system model of the locomotio...

INTRODUCTION Kinematic gait analysis via the multi-segmental Oxford foot model (OFM) may be a valuable addition to the biomechanical examination of the foot and ankle. The aim of this study is to assess the repeatability of the OFM in healthy subjects. METHODS Nine healthy subjects, without a history of lower extremity injury, were recruited. Markers were placed according to the OFM requireme...

BACKGROUND Plantar heel pain is a common foot disorder aggravated by weight-bearing activity. Despite considerable focus on therapeutic interventions such as orthoses, there has been limited investigation of footwear-related issues in people with plantar heel pain. The aim of this study was to investigate whether people with plantar heel pain experience footwear-related difficulties compared to...

Though the effects of imposed trunk posture on human walking have been studied, less is known about such locomotion while accommodating changes in ground level. For twelve able participants, we analyzed kinematic parameters mainly at touchdown and toe-off in walking across a 10-cm visible drop in ground level (level step, pre-perturbation step, step-down, step-up) with three postures (regular e...

Foot-related problems are prevalent across the globe, and this issue is aggravated by presence of diabetes mellitus. Diabetic-foot-related issues include extreme foot pain, plantar corns, diabetic ulcers. To assess these conditions, accurate characterization pressure required. In work, an in-shoe, low-cost, multi-material measuring insole, based on a piezoresistive material, was developed. The ...

Spatiotemporal parameters can characterize the gait patterns of individuals, allowing assessment their health status and detection clinically meaningful changes in gait. Video-based markerless motion capture is a user-friendly, inexpensive, widely applicable technology that could reduce barriers to measuring spatiotemporal clinical more diverse settings. Two studies were performed determine whe...

Background: Hypoglycemia is one of the most common neonatal disorders, associated with severe complications. There has been a great deal of controversy regarding the definition and screening of hypoglycemia. Therefore, in this study, we aimed to determine a cut-off value for blood glucose level in glucometer readings. Methods: This cross-sectional study was conducted on 238 newborns at risk of ...

Abstract Gait analysis is a systematic study of human movement. Combining wearable foot pressure sensors and machine learning (ML) solutions for high-fidelity body pose tracking from RGB video frames could reveal more insights into gait abnormalities. However, accurate detection heel strike (HS) toe-off (TO) events crucial to compute interpretable parameters. In this work, we present an experim...
