Scapho-trapezio-trapezoid arthrodesis was originally performed for the treatment of scapho-lunate instability. However, only a few publications have described this technique for treatment of osteoarthritis of the scapho-trapezio-trapezoid (STT) joint. The purpose of this paper is to analyze the results of triscaphoid arthrodesis for STT osteoarthritis with a long-term follow-up. Thirteen cases ...

The authors report a rare case of the bilateral floating forearm in a 25year-old man , who presented the combination of injuries after a fall from third floor; The bilateral dislocation of the elbow and fracture –dislocation of two wrists .The elbows were reduced orthopedically and the right wrist was treated with external fixator and pinning in the left wrist. At twelve months the patient only...

We introduce a method, known as one-dimensional sonomyography (1-D SMG), that uses A-mode ultrasound signals to detect dynamic thickness changes in skeletal muscle during contraction. We custom-designed a 1-D SMG system to collect synchronized A-mode ultrasound, joint angle, and surface electromyography (EMG) signals of forearm muscles during wrist extension. We extracted the 1-D SMG signal fro...

In snowboarding, the wrist is the most common injury site, as snowboarders often put their arms out to cushion a fall. This can result in a compressive load through the carpals coupled with wrist hyperextension, leading to sprains or fractures. Wrist protectors are worn by snowboarders in an effort to reduce injury risk, by decreasing impact forces and limiting wrist hyperextension during falls...

Tenodesis refers to opposition of the thumb and index finger with either active or passive wrist extension. Achieving a functional tenodesis grasp is a primary focus of therapy for such a person, to enable participation in activities of daily living. Tenodesis grasp is achieved with people who have a complete C6 level of quadriplegia, using a range of clinical interventions: passive wrist and h...

Because wrist rotation dynamics are dominated by stiffness (Charles SK, Hogan N. J Biomech 44: 614-621, 2011), understanding how humans plan and execute coordinated wrist rotations requires knowledge of the stiffness characteristics of the wrist joint. In the past, the passive stiffness of the wrist joint has been measured in 1 degree of freedom (DOF). Although these 1-DOF measurements inform u...

Purpose: The aim of this study is to investigate the effects of Kinesio taping on severity of pain, the power for taking hand, functional activity and we undertook a literature review to produce evidence-based recommendation for the use of Kinesio tape in patients with lateral epicondylitis. Methods: A literature search was done in google scholar, pubmed, science direct, proquest, medline,...

Sonomyography (SMG) is the signal we previously termed to describe muscle contraction using real-time muscle thickness changes extracted from ultrasound images. In this paper, we used least squares support vector machine (LS-SVM) and artificial neural networks (ANN) to predict dynamic wrist angles from SMG signals. Synchronized wrist angle and SMG signals from the extensor carpi radialis muscle...
