BACKGROUND AND PURPOSE Ischemic stroke is the leading cause of upper extremity motor impairments. Although several well-characterized experimental stroke models exist, modeling of upper extremity motor impairments, which are unique to primates, is not well established. Cortical representation of dexterous movements in nonhuman primates is functionally and topographically similar to that in huma...

OBJECTIVES To determine the prevalence and characteristics of sonographically evident upper-extremity deep vein thrombosis in symptomatic Chinese patients and identify its associated risk factors. SETTING Regional hospital, Hong Kong. PATIENTS Data on patients undergoing upper-extremity venous sonography examinations during a 13-year period from November 1999 to October 2012 were retrieved....

INTRODUCTION Contemporary dogma has classically attributed hand dysfunction following hemodialysis arteriovenous fistula (AVF) placement to regional ischemia. We hypothesize that hemodynamic perturbations alone do not entirely explain the postoperative changes in hand function and, furthermore, that various elements of hand function are differentially affected following surgery. METHODS Bilat...

Among the hemiplegic disorders caused by complications of stroke, the functional recovery of upper extremities is slower than the recovery of other functions. In this study, a wireless motion tracking system to transfer motion data on the patient's upper extremity movements was developed using inertial sensors consisting of a three-axis accelerometer, gyro, and geo-magnetic sensor. In addition,...

this workshop features, (live) demonstration of sonographic technique of the upper extremity joints; patient positioning; transducer choices, operation and position on the anatomic landmarks; optimal evaluation of the anatomic structures in shoulder, elbow and wrist; hopefully on thursday or friday.

BACKGROUND The purpose of this study is to characterise the injuries, outcomes, and disabling conditions of the isolated, combat-related upper extremity amputees in comparison to the isolated lower extremity amputees and the general amputee population. METHODS A retrospective study of all major extremity amputations sustained by the US military service members from 1 October 2001 to 30 July 2...

Objectives: Venous thromboembolis is a clinical condition that often occurs from deep vein thrombosis of lower extremity. The incidence of deep venous thrombosis in the etiology of pulmonary thromboembolism may be as high as 90%. Doppler ultrasonography of lower extremities is recommended generally to determinate the etiology of pulmonary thromboembolism. The aim of this study is to present the...
