[Purpose] The purpose of this study was to access the effect of weight bearing exercise (treadmill exercise) and non-weight-bearing exercise (swimming exercise) on gait in the recovery process after a sciatic nerve crush injury. [Subjects and Methods] Rats were randomly divided into a swimming group (n=3) with non-weight-bearing exercise after a sciatic nerve crush and a treadmill group (n=3) w...

The mechanics of reversible adhesion of the gecko is investigated in terms of the attachment and detachment mechanisms of the hierarchical microstructures on its toe. At the bottom of the hierarchy, we show that a spatula pad of tiny thickness can be well absorbed onto a substrate with a large surface area and a highly constrained decohesion process zone, both of which are beneficial for robust...

In this paper standing balance control of a biped with toe-joint is presented. The model consists of an inverted pendulum as the upper body and the foot contains toe-joint. The biped is actuated by two torques at ankle-joint and toe-joint to regulate the upper body in upright position. To model the interaction between foot and the ground, configuration constraints are defined and utilized. To s...

BACKGROUND Infants with Down syndrome (DS) have delayed walking and produce less-coordinated walking patterns. OBJECTIVE The aim of this study was to investigate whether 2 treadmill interventions would have different influences on the development of joint kinematic patterns in infants with DS. DESIGN Thirty infants with DS were randomly assigned to a lower-intensity, generalized (LG) treadm...

an experiment was conducted using 640 day-old sexed commercial broiler chicks (ross 308 strain) from 10 to 49 days of age. the experimental design was a completely randomized factorial one. the experimental units (pens) contained 20 chicks each and were allotted at random to 4 dietary treatments × two sexes with 4 replicates per treatment. four dietary treatments were formulated based on corn a...

The use of smartphones in clinical practice is steadily increasing with the availability of low cost/freely available "apps" that could be used to assess human gait. The primary aim of this manuscript is to test the concurrent validity of kinematic measures recorded by a smartphone application in comparison to a 3D motion capture system in the sagittal plane. The secondary aim was to develop a ...

background:   to introduce our experience of using the free neurovascular flap from great and second toe. methods:   thirteen patients (fifteen fingers) sought surgical treatment for soft tissue defects of the hand at our medical institutin between march 2006 and september 2009. in two patients, fibular side skin-nail flaps of great toe were applied to cover the dorsal defect of distal thumb. i...

The aim of this study was to determine that low-intensity pulsed ultrasound (LIPUS) at an intensity 140 mW/cm2 promotes functional and histologic improvements in sciatic nerve crush injury a rat model investigate changes over time relevant growth factors receptors, exploring the mechanism LIPUS recovery process after injury. Toe angle toe-off phase, regenerative axonal length, myelinated fiber ...

BACKGROUND Knowledge of joint kinematics in the healthy and diseased joint may be useful if surgical techniques and joint replacement designs are to be improved. To date, little is known about the kinematics of the arthritic tibiotalar joint and its effect on the kinematics of the subtalar joint. MATERIALS AND METHODS Kinematics of the ankle joint complex (AJC) were measured in six patients w...

BACKGROUND The ostrich is a cursorial bird with extraordinary speed and endurance, especially in the desert, and thus is an ideal large-scale animal model for mechanic study of locomotion on granular substrate. METHODS The plantar pressure distributions of ostriches walking/running on loose sand/solid ground were recorded using a dynamic pressure plate. RESULTS The center of pressure (COP) ...
