OBJECTIVE The authors aimed to develop a mechanical model for delivering controlled impact injuries to an articular cartilage surface, with the ability to control peak contact pressure while maintaining a constant rate of loading across all impact levels. METHODS A pendulum-style impactor with a direct contact interface was fabricated, based on previously published successful models. This imp...

This paper describes a new method for measuring the tonguepalatal contact pressure using a thin pressure sensor and its application for speech research. The new pressure sensor is composed of thin pressure sensitive ink whose electrical resistance is proportional to the physical forces applied to the sensor. Several sensors were arranged on the surface of the palatal plate. This setup was used ...

BACKGROUND Osteochondral allograft transplantation is technically demanding. It is not always possible to place the surface of the graft perfectly flush with the surrounding cartilage. One must often choose between placing at least some portion of the surface of the graft slightly elevated or recessed. The effect of this choice on joint contact pressure is unknown. PURPOSE This study was unde...

BACKGROUND To compare the intraocular pressure readings obtained with the iCare rebound tonometer and the 7CR non-contact tonometer with those measured by Goldmann applanation tonometry in treated glaucoma patients. DESIGN A prospective, cross-sectional study was conducted in a private tertiary glaucoma clinic. PARTICIPANTS OR SAMPLES One hundred nine (54 males : 55 females) patients includ...

-A linear perturbation method is used to examine the stability of a unidirectional solidification problem in which a liquid, initially at the melting temperature, becomes solidified by heat transfer across a pressure-dependent thermal contact resistance to a plane mold. The contact pressure will be influenced by thermal distortion in response to the instantaneous temperature field in the solidi...

BACKGROUND Paralysis of the common peroneal nerve is one of the relatively common nerve injuries related to the lithotomy position with the use of a knee-crutch/leg-holder system. Several risk factors have been implicated in lithotomy position-related common peroneal nerve paralysis during operation. MATERIALS AND METHODS In the present study, 21 young healthy volunteers participated in the i...
