Researchers and clinicians are increasingly using plantar pressure and force measurement system to evaluate foot functions. This research evaluates the quality and reliability of a Tekscan HR mat to study the plantar pressures and forces acting during walking, running, jumping, and standing of healthy subjects. The following regions of the foot were investigated: heel, mid foot, metatarsophalan...

AIMS To assess the usefulness of three-dimensional transoesophageal echocardiography (3D-TOE) vs. two-dimensional (2D)-TOE in the evaluation of morphological and dynamic findings of aortic dissection, and compare the results with those obtained by multi-slice computed tomography (CT). METHODS AND RESULTS Twenty-six patients (21 men and 5 women, median age: 67 years, range: 28-74 years) diagno...

The determination of gait events such as heel strike and toe-off provide the basis for defining stance and swing phases of gait cycles. Two algorithms for determining event times for treadmill and overground walking based solely on kinematic data are presented. Kinematic data from treadmill walking trials lasting 20-45s were collected from three subject populations (healthy young, n=7; multiple...

1 Motivation Due to experimental difficulties, almost no scientific evidence to date definitively indicates that one lowerlimb prosthesis performs better than another [3]. A model of walking that is simple enough to allow systematic exploration of prosthesis design variables, yet detailed enough to accurately capture step dynamics, could help fill this gap. Unfortunately, such a model does not ...

The design of a knee joint is a key issue in robotics and biomechanics to improve the compatibility between prosthesis and human movements and to improve the bipedal robot performances. We propose a novel design for the knee joint of a planar bipedal robot, based on a four-bar linkage. The dynamic model of the planar bipedal robot is calculated. We design walking reference trajectories with dou...

only two facts on which all are agreed. The first is, that the complaint is caused by the wearing of tight boots; the second, that it is not ingrowing of the toe-nail at all, but overgrowing of the toe-flesh. With reference to the first point, it seems to have struck no one as peculiar that the leaving off tight boots is by no means a cure for the malady. Sublata causa, tollitxir effectus ought...

BACKGROUND Minimum toe clearance is a critical gait event because it coincides with peak forward velocity of the swing foot, and thus, there is an increased risk of tripping and falling. Trans-tibial amputees have increased risk of tripping compared to able-bodied individuals. Assessment of toe clearance during gait is thus clinically relevant. In able-bodied gait, minimum toe clearance increas...
