Foot joint pressures during dynamic gait simulation
نویسندگان
چکیده
Methods 5 fresh cadaveric specimens were connected to a dynamic gait simulator. I-scan #6900 sensors® were calibrated and surgically inserted into the subtalar (ST), naviculocuneiform (NC) calcaneocuboid (CC), and talonavicular (TN) joints using a joint spreader. Each foot was walked multiple trials across a force platform for three conditions (normal, flatfoot, flatfoot-orthotic). The flatfoot condition was created by detaching the posterior tibial tendon from the simulator and surgically releasing the spring ligament complex and the plantar fascia. Joint pressure data were collected at 100 Hz. Peak pressures were averaged within subjects and effect sizes were calculated between conditions.

Energy Dissipation Rate Control Via a Semi-Analytical Pattern Generation Approach for Planar Three-Legged Galloping Robot based on the Property of Passive Dynamic Walking
In this paper an Energy Dissipation Rate Control (EDRC) method is introduced, which could provide stable walking or running gaits for legged robots. This method is realized by developing a semi-analytical pattern generation approach for a robot during each Single Support Phase (SSP). As yet, several control methods based on passive dynamic walking have been proposed by researchers to provide an...
متن کاملA Dynamic Finite Element Analysis of Human Foot Complex in the Sagittal Plane during Level Walking
The objective of this study is to develop a computational framework for investigating the dynamic behavior and the internal loading conditions of the human foot complex during locomotion. A subject-specific dynamic finite element model in the sagittal plane was constructed based on anatomical structures segmented from medical CT scan images. Three-dimensional gait measurements were conducted to...
متن کاملIs there a relationship between static and dynamic ankle joint dorsiflexion during gait in people with a history of neuropathic ulceration?
Background The inclusion of limited joint mobility (LJM) as a risk factor for plantar neuropathic foot ulceration in diabetes is interspersed throughout the literature. This is commonly believed to occur through connective tissue thickening and stiffening, thereby reducing available static and dynamic motion below that required for normal foot function. High underfoot pressures are postulated t...
متن کاملDesign and Evaluation of an Articulated Ankle Foot Orthosis with Plantarflexion Resistance on the Gait: a Case Series of 2 Patients with Hemiplegia
Ankle-foot orthoses (AFOs) have been described to have positive effects on the gait biomechanics in stroke patients. The plantarflexion resistance of an AFO is considered important for hemiplegic patients, but the evidence is still limited. The purpose of this case series was to design and evaluate the immediate effect of an articulated AFO on kinematics and kinetics of lower-limb joints in str...
متن کاملDynamic foot movement in children treated for congenital talipes equinovarus.
The aim of this study was to define objectively gait function in children with treated congenital talipes equinovarus (CTEV) and a good clinical result. The study also attempted an analysis of movement within the foot during gait. We compared 20 children with treated CTEV with 15 control subjects. Clinical assessment demonstrated good results from treatment. Three-dimensional gait analysis prov...
