the aim of study was to investigate and compare the concentric torque of quadriceps and hamstring muscles and timed-walking test in two groups. thus, one group of healthy subjects and one group of patients with low grade of tibiofemoral osteoarthritis (oa) were selected. concentric torque of quadriceps and hamstring were measured in both groups. besides, pain measurement, timed-walking test, ra...

introduction: the purpose of this study was to compare the accuracy of the torque wrenches used in different dental implant systems. methods: we evaluated 42 torque wrenches used in different dental clinics in mashhad, iran, using a digital torque meter (mark 10). high (25, 30 and 35 n·cm) and low (15 n·cm) levels of torque were examined. ten tests were performed on each wrench, and the mean va...

Edgewise orthodontic treatment utilizes a force couple in order to achieve labial-lingual tooth angulation. Two self-ligating brackets (Damon Q and Speed) were examined across a range of clinically relevant torques in order to assess the loading and unloading curves and bracket deformation. A previously developed torquing and load measurement system was utilized to rotate a 0.199 × 0.25 in stai...

[Purpose] The primary purpose of this study was to evaluate the intraclass correlation coefficient in obtaining the torque of the hip muscle strength during a robot-assisted rehabilitation treatment. [Subjects] Twenty-four patients (15 males, 9 females) with spinal cord injury participated in the study. [Methods] The subjects were asked to walk during robot-assisted rehabilitation, and the torq...

In this article image processing of a binary single track code for determining torque is presented. The aim of the research is to determine the absolute angular position of a shaft and the applied torque. For capturing an image of the binary code two independent imaging modules are used, both allowing for measuring the angular position and rotational speed. Combining both imaging modules, torqu...

This study was performed in order to determine the loss of strength of the dorsiflexors in healthy persons after immobilization of the ankle, and the ability of these muscles to regain strength. First, isometric ankle dorsiflexion strength was measured in 33 healthy male and 39 female subjects in age categories 20-40 and 40-80 years, in order to obtain reference data and to determine the reprod...

Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1581. 81 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-513-0117-4. Wind power is an established mean of clean energy production and the modern horizontal axis wind turbine has become a common sight. The need for maint...

-This paper presents for the study of torque transducer (torque sensor) calibration built into a rotating shaft, in this case uses strain gauge, which was done with, and the output signal of the "voltage (mV/V)" has been taken for each weight, increasing and decreasing the weights. The data have been taken three times which they have been divided into three series. First and foremost, the avera...

The aim of this study was to assess the effect of bracket type on the labiopalatal moments generated by lingual and conventional brackets. Incognito™ lingual brackets (3M Unitek), STb™ lingual brackets (Light Lingual System; ORMCO), In-Ovation L lingual brackets (DENTSPLY GAC), and conventional 0.018 inch slot brackets (Gemini; 3M Unitek) were bonded on identical maxillary acrylic resin models ...
