The active state describes the force developed in a muscle when the contractile elements are neither lengthening nor shortening. Recently it was suggested that perturbations used to measure the active state also alter the time-course of the active state. The present research was undertaken to assess quantitatively the effect of two such perturbations, isotonic shortening and quick release, on t...

[abstract] We present a retrospectively review of outcomes of the first fifteen patients who underwent proximal interphalangeal (PIP) joint arthroplasty and were treated using the same early active motion rehabilitation regime introduced by the therapy department at Mount Vernon Hospital. The regime utilises early motion of the PIP joint while protecting the arthroplasty with a small static spl...

BACKGROUND Decreasing the stiffness of locked plating constructs can promote natural fracture healing by controlled dynamization of the fracture. This biomechanical study compared the effect of 4 different stiffness reduction methods on interfragmentary motion by measuring axial motion and shear motion at the fracture site. METHODS Distal femur locking plates were applied to bridge a metadiap...

background: in radiation treatment of moving targets located in thorax region of patient body, the delivered dose does not match with the planned treatment, resulting in some over and under dosage in the tumor volume, as a function of motion magnitude and frequency. several efforts have been done to investigate the target motion effects on dose distribution in the target and surrounding normal ...

In many natural and technological multi-phase systems, bubbles are exposed to surface-active contaminants (surfactants) that may cover the whole or part of bubble interface. A partial coverage interface result in a spontaneous self-propulsion mechanism, which is yet not fully characterized. Here, dynamics partially contaminated examined using high-fidelity simulations. The simulations enable de...

In the Case Report "Early Controlled Motion Following Flexor Tendon Graft" (July 1988), the authors gave an excellent overview of the physio­ logical rationale for early controlled motion. I must express my concern, however, at their conclusion as stated: "The good functional results achieved suggest that a rehabilitation regimen consisting of the palmar pulley sys­ tem, a PIP joint block, and ...
