Extracting Time Accurate Acceleration Vectors From Nontrivial Accelerometer Arrangements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sportsrelated concussions are of significant concern in many impact sports, and their detection relies on accurate measurements of the head kinematics during impact. Among the most prevalent recording technologies are ...
The Envelope of Physiological Motion of the First Carpometacarpal Joint
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Much of the hand's functional capacity is due to the versatility of the motions at the thumb carpometacarpal (CMC) joint, which are presently incompletely defined. The aim of this study was to develop a mathematical model ...
An Approach to Robotic Testing of the Wrist Using Three-Dimensional Imaging and a Hybrid Testing Methodology
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Robotic technology is increasingly used for sophisticated in vitro testing designed to understand the subtleties of joint biomechanics. Typically, the joint coordinate systems in these studies are established via palpation ...
Evaluation of Hand Motion Capture Protocol Using Static Computed Tomography Images: Application to an Instrumented Glove
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There has been a marked increase in the use of hand motion capture protocols in the past 20 yr. However, their absolute accuracies and precisions remain unclear. The purpose of this technical brief was to present a method ...
Polar Histograms of Curvature for Quantifying Skeletal Joint Shape and Congruence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of articular joint shape and congruence on kinematics, contact stress, and the natural progression of joint disease continues to be a topic of interest in the orthopedic biomechanics literature. Currently, the ...
Subject Specific Carpal Ligament Elongation in Extreme Positions, Grip, and the Dart Thrower's Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study examined whether the radiocarpal and dorsal capsular ligaments limit endrange wrist motion or remain strained during midrange wrist motion. Fibers of these ligaments were modeled in the wrists of 12 subjects ...
Kinematic Accuracy in Tracking Total Wrist Arthroplasty With Biplane Videoradiography Using a Computed Tomography-Generated Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Total wrist arthroplasty (TWA) for improving the functionality of severe wrist joint pathology has not had the same success, in parameters such as motion restoration and implant survival, as hip, knee, and shoulder ...
