CONTEXT Clinicians require portable, valid, and cost-effective methods to monitor knee joint-position-sense (JPS) ability. OBJECTIVE To examine the criterion-related validity of image-capture JPS measures against an isokinetic-dynamometer (IKD) procedure. DESIGN Random crossover design providing a comparison of knee JPS measures from image capture and IKD procedures. PARTICIPANTS 10 healt...

Research on damage of gears and gear pairs using vibration signals remains very attractive, because vibration signals from a gear pair are complex in nature and not easy to interpret. Predicting gear pair defects by analyzing changes in vibration signal of gears pairs in operation is a very reliable method. Therefore, a suitable vibration signal processing technique is necessary to extract defe...

Abstract Wireless dynamometers are an adequate solution to measure mechanical loads where the use of cables is not practicable. Proprietary solutions applied in most cases found out literature on wireless dynamometers. However, these have a high market price, and they black-box systems, which limit their application customized conditions. In this context, study presents development dynamometer ...

The condition of a cutting tool is an important factor in manufacturing processes. Tool wear has a strong influence on the cutting forces, resulting in a poor surface finish and impacting on the dimensional tolerance of the workpiece. Therefore, the use of a dynamometer during machining to measure cutting forces is a well-known approach but it has several limitations such as high cost, poor per...

Strength, or maximum joint torque, is a fundamental factor governing human movement, and is regularly assessed for clinical and rehabilitative purposes as well as for research into human performance. This study aimed to identify the most appropriate protocol for fitting a maximum voluntary torque function to experimental joint torque data. Three participants performed maximum isometric and conc...

The purpose of this study was to determine the effect of dynamometer and joint axis misalignment on measured isometric knee-extension moments using inverse dynamics based on the actual joint kinematic information derived from the real-time X-ray video and to compare the errors when the moments were calculated using measurements from external anatomical surface markers or obtained from the isoki...

[Purpose] To compare measurements of knee extensor and flexor muscle strength performed using a hand-held dynamometer and an isokinetic dynamometer in apparently healthy subjects. [Subjects and Methods] Thirty adult volunteers underwent knee muscle strength evaluation using an isokinetic or a hand-held dynamometer. [Results] Strong positive correlations were found between the 2 methods, with co...
