BACKGROUND Tests that are usually employed for the clinical assessment of muscular strength have notable disadvantages. The Modified Sphygmomanometer Test (MST) is a promising method because it is low-cost and provides objective measures. OBJECTIVES To investigate the most adequate method and sources of outcome values for the assessment of strength with the MST. METHOD Methodological study ...
The most common machining methods in machining are turning, milling, drilling and grinding. Significant studies are conducted in machining industry and academic circles in order to measure the cutting force during these processes. This study includes a review of these studies, a categorization of similar ones and detailed information about measurement systems. Through the review of studies, we ...
BACKGROUND Several problems are associated with manual muscle testing and dynamometry in the hands of patients with Charcot-Marie-Tooth (CMT) disease. OBJECTIVE To evaluate the efficacy of the Rotterdam Intrinsic Hand Myometer (RIHM) to directly measure intrinsic hand muscle strength in CMT disease. METHODS We measured hand muscle strength and hand function in 41 patients with CMT disease. ...
Fifty-three specialist women physical education students were measured anthropometrically and from these measurements somatotype and body composition were estimated. Leg, back and grip strength dynamometers were used to measure strength indices. Arm strength was calculated from each subject's pull-ups and push-ups and lung capacity was measured using a spirometer. The somatotype ratings and per...
Proposal of Methodology and Calibration of Dynamometers for Quantification of Forces in Anchor Bolts
It has been observed consistently and is well accepted that the steady-state isometric force after active muscle stretch is greater than the corresponding isometric force for electrically stimulated muscles and maximal voluntary contractions. However, this so-called force enhancement has not been studied for submaximal voluntary efforts; therefore, it is not known whether this property affects ...
A neural net approach was used to classify and analyze combinations of the physiological and kinematic responses (the factor patterns) of experienced and novice individuals during wheelchair propulsion, and to determine the key characteristics (individual factors) used in making this determination. A sequence of artificial neural networks (ANN) was developed and used to classify differences bet...
A new high-bandwidth transient dynamometer has been designed and is being built for application to a single-cylinder research engine. The goal of this system is to accurately reproduce all of the dynamic, instantaneous torques that this single-cylinder would experience if it were in a multi-cylinder engine. This is accomplished by calculating these instantaneous torques in real time using a det...
In this paper, a high dynamic test-bed control problem for high dynamic vehicle simulation is studied in order to improve the tracking of speed and torque. As the system is nonlinear and square (2x2) with two inputs and two outputs, a multi-input multi-output (MIMO) system-identification problem is discussed. The test-bed data are processed using a fast frequency domain methodology to build a n...
