Comparison of Rolyan and Jamar dynamometers for measuring grip strength.
This study compared the Jamar and Rolyan hydraulic dynamometers to determine their concurrent validity with known weights as well as their inter-instrument reliability and concurrent validity for measuring grip strength in a clinical setting. Thirty females and 30 males were tested on these two grip strength measurement devices using a repeated measure design. Results showed that the Jamar and ...
متن کاملModel-based Control Design for Ic-engines on Dynamometers: the Toolbox 'optimot'
: A new approach towards a model-based optimization of IC engine control on dynamometers is presented in this paper. The proposed methodology comprises advanced measurement strategies for a fast dynamic measurement of engine characteristics on dynamometers (DYNMET), a model-based offline optimization of feedforward control maps (STATOPT), and the optimization of dynamic transitions of turbochar...
متن کاملReliability of stabilised commercial dynamometers for measuring hip abduction strength: a pilot study.
BACKGROUND Reliable quantification of hip abductor strength in a clinical setting is challenging. OBJECTIVES To examine the intrarater and interrater reliability of three commonly used commercial dynamometers in the measurement of hip abduction. METHODS Supine gravity minimised measures of unilateral hip abduction strength were recorded in 10 women (mean (SD) age 23.5 (1.9) years) using thr...
متن کاملA Novel Strategy to Eliminate the Influence of Water Adsorption on Quartz Surfaces on Piezoelectric Dynamometers
Piezoelectric dynamometers are out of use in high humidity. Experimental results showed that piezoelectric coefficients measured by the force-induced charges method initially fluctuated in a small range and then was unstable, and they could not be measured at high relative humidity (RH). The traditional shielding method-insulation paste was not quiet convenient, and it even added the weight of ...
متن کاملNormative values for isometric muscle force measurements obtained with hand-held dynamometers.
BACKGROUND AND PURPOSE The extent of a patient's impairment can be established by comparing measurements of that patient's performance with normative values obtained from apparently unimpaired individuals. Only a few studies have described normative values for muscle strength measured by hand-held dynamometry. The purpose of this study of older adults, therefore, was to obtain normative values ...
