BACKGROUND Ankle strength is often impaired in some of the most common neuromuscular disorders. Consequently, strength generated around this joint is important to assess, because it has a great impact on balance and gait. The objectives of this study were to establish normative data and predictive equations for both ankle dorsi- and plantar-flexion strength from a population of healthy subjects...

Objective: The prevention of thumb joints flexion help cure de Quervain tenosynovitis. thumb, therefore, is being immobilized in the abduction position by splinting. Thumb can be away from palm (palmar abduction) or fingers (radial abduction), which are done two different planes. To authors' knowledge, literature has not specified kind better treatment outcomes and functions. This study aimed t...

BACKGROUND Grip strength is a variable which may be important to measure and follow in various populations. A new dynamometer with high accuracy and sensitivity has recently been developed to assess grip strength. The objectives of this work were to provide norms of maximal isometric grip strength measured with this new dynamometer (the MyoGrip device), to assess the reliability of measurements...

Background: Prevalence estimates for sarcopenia vary depending on the ascertainment criteria and thresholds applied. We aimed to estimate prevalence of using two international definitions but employing Australian population-specific cut-points. Methods: Participants (n = 665; 323 women) aged 60–96 years old were from Geelong Osteoporosis Study. Handgrip strength (HGS) was measured by dynamomete...

The objective of this study was to explore the joint kinetics of upper extremities during wheelchair maneuvers. A high incidence of musculoskeletal injuries has been reported due to the overuse and high repetitive motion of wrist, elbow and shoulder during wheelchair propulsion. Studies have been conducted with the use of a dynamometer or treadmill to simulate propulsion on level or inclined su...

This paper describes an application of an engine cycle simulation code (WAVE) in co-simulation with a control and dynamics modelling package (Matlab Simulink) to provide total vehicle system modelling capability. The models presented form the basis of an Analytical Calibration CAE toolset allowing the definition of many electronic control unit (ECU) calibration parameters in the CAE environment...

Reducing air pollution caused by emissions from road traffic, especially in urban areas, is an important goal of legislators and the automotive industry. The introduction so-called “Real Driving Emission” (RDE) tests for homologation vehicles with internal combustion engines according to EU6d legislation was a fundamental milestone vehicle powertrain development. Due non-reproducible on-road em...

OBJECTIVE To determine the short- and long-term test-retest reliability of maximum isometric trunk moment measurements in healthy volunteers over 50 years of age, to compare these results with those from volunteers younger than 50 years, and to test whether volunteers' anticipatory emotional state affects the precision of these measurements. METHODS Forty-two older persons (21 females; age ra...

Purpose: To investigate the differences in neural control of back muscles activated during the eccentric vs. the concentric portions of a cyclic, submaximal, fatiguing trunk extension exercise via the analysis of amplitude and time-frequency parameters derived from surface electromyographic (SEMG) data. Methods: Using back dynamometers, 87 healthy volunteers performed three maximum voluntary is...

Isokinetic contraction is the muscular contraction that accompanies constant velocity limb movements around a joint. The velocity of movement is maintained constant by a special dynamometer. The resistance of the dynamometer is equal to the muscular forces applied throughout the range of movement. This method allows the measurement of the muscular forces in dynamic conditions and provides optim...
