The aim of this paper is to investigate mechanical functioning of a single skeletal muscle, active within a group of (previously) synergistic muscles. For this purpose, we assessed wrist angle-active moment characteristics exerted by a group of wrist flexion muscles in the rat for three conditions: (i) after resection of the upper arm skin; (ii) after subsequent distal tenotomy of flexor carpi ...

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...

Carpal/Wrist instability is the result of a large variety of conditions. Any alteration of the shape of the wrist bones or the connections between them can affect the dynamic balance of forces and the wrists unique multiplane movements. Sensorimotor function is a term used to describe sensory, motor and central processes pertaining to joint stability. Wrist joint proprioception and sensorimotor...

Over the past three decades, much research in motor neuroscience has focused onunderstanding how humans make coordinated reaching movements, yielding valuableinsight into the planning and control of reaching movements, and establishing afoundation for robot-assisted rehabilitation. The goal of this doctoral research was toprovide a quantitative characterization of humans’ wr...

P rimary care physicians often are the first to evaluate and treat a patient with wrist pain. Although the wrist consists of a complicated group of bony articulations and soft tissues, many family physicians often use wastebasket diagnoses such as “wrist sprain” or “tendonitis” that do little to identify the true pathology of the condition. Despite the challenges this complex of joints presents...

OBJECTIVE This study compared the total wrist range of motion permitted by four different styles of wrist extension orthoses and the free hand. METHOD Using a repeated-measures, counterbalanced design, 40 healthy female volunteers 20 to 39 years of age shot a basketball while free handed and while wearing each of four wrist extension orthoses: AlignRite; Rolyan D-Ring Long; Rolyan D-Ring Shor...

OBJECTIVES The primary objective was to investigate the effects of continuous typing on median nerve changes at the carpal tunnel region at two different keyboard slopes (0° and 20°). The secondary objective was to investigate the differences in wrist kinematics and the changes in wrist anthropometric measurements when typing at the two different keyboard slopes. METHODS Fifteen healthy right...

PURPOSE This study was to identify the effects of Nei-Guan acupressure using a wrist band on postoperative nausea and vomiting after middle ear surgery. METHODS The study design was a nonequivalent control group non-synchronized posttest design. Forty patients were assigned into two groups of 20 patients, the wrist band group and the control group. In the wrist band group, acupressure was app...
