High ankle sprains represent a severe injury in sports. External foot rotation is suspected in these cases, but the mechanism of injury remains unclear. The objective of the current study was to integrate in vitro and in vivo experiments along with computational models based on rigid bone surfaces and deformable ligaments of the ankle to investigate the external foot rotation inju...

Single, double, and triple hindfoot arthrodeses are used to correct hindfoot deformities and relieve chronic pain. However, joint fusion may lead to dysfunction in adjacent articular surfaces. We compared range of motion in adjacent joints before and after arthrodesis to determine the effects of each procedure on joint motion. The theory of moment of couple, bending moment and balanced loading ...

INTRODUCTION Nerve conduction studies provide information regarding the status of peripheral nerves, but relationships with sensorimotor capacities that influence mobility have not been defined. METHODS A secondary analysis was conducted on data from 41 older subjects (20 women and 21 men, age 69.1 ± 8.3 years), including 25 with diabetic neuropathy of varying severity and 16 without diabetes...

CONTEXT There is limited information on fatigue of the evertors on frontal plane joint position sense (JPS). OBJECTIVE To examine the effects of isokinetic concentric-eccentric fatigue of the evertors on frontal plane JPS of the ankle. DESIGN A2 x 4 factorial design. SETTING Research Laboratory. PATIENTS OR OTHER PARTICIPANTS 40 male and female healthy subjects. INTERVENTIONS JPS was ...

BACKGROUND Many methods for the correction of the inverted nipple have been described, but no consensus has been reached as to which is the best approach. OBJECTIVE We describe an integrated approach to the correction of nipple inversion that minimizes ductal disruption. METHODS We performed initial nipple eversion using gentle traction with a skin hook. The nipple base was approached with ...

OBJECTIVE Head-to-head comparison of the success rate of jejunal placement of a new electromagnetically visualized jejunal tube with that of the endoscopic technique in critically ill patients. DESIGN : Prospective, randomized clinical trial. SETTING Two intensive care units at a university hospital. PATIENTS : A total of 66 critically ill patients not tolerating intragastric nutrition. ...

The cytoarchitectonics of the telencephalon of the channel catfish, Ictalurus punctatus, are described as a basis for experimental analysis of telencephalic afferents and efferents. The olfactory bulb comprises: (1) an outer layer of olfactory nerve fibers, (2) a glomerular layer, (3) an external cell layer, (4) an inner fiber layer, and (5 ) an internal cell layer. The telencephalic hemisphere...

QUESTION What is the effect of wearing splints at night to stretch the plantarflexors on dorsiflexion range of motion (ROM) in people with Charcot-Marie-Tooth disease? DESIGN Randomised, assessor-blinded, cross-over trial. PARTICIPANTS 14 people (1 dropout) aged 7 to 30 years with Charcot-Marie-Tooth disease Type 1A and with < or = 15 degrees dorsiflexion range of motion (ROM). INTERVENTI...

BACKGROUND Orthotic devices can be a successful treatment for lower extremity injuries. However, the high cost of custom devices prevents some patients from purchasing them. Some orthotic companies have begun to offer a less expensive, semi-custom alternative. The purpose of this study was to examine whether the semi-custom devices can provide similar rearfoot control and comfort as custom devi...

Background: Injury to the common peroneal nerve disrupts the motor control pathway to ankle dorsiflexors and evertors, as well as toe extensors, resulting in pathological gait and foot drop. Direct external compression on the fibular head is the most frequent cause of peroneal nerve impairment and has poor prognosis. Methods and Patients: Here, we report the surgical outcome of 21 patients with...
