Analysis of the tonic vibration reflex: influence of vibration variables on motor unit synchronization and fatigue
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-05)
The influence of vibration frequency (40, 80, 100, 120, 150, or 200 Hz) at selected displacement amplitudes (0.2, 0.3 mm) on tonic vibration reflex (TVR) characteristics was investigated. The degree of synchronization of ...
A biomechanical model of the lumbosacral joint during lifting activities
(Elsevier, 1985)
A biomechanical model of the lumbosacral region was constructed for the purpose of systematically studying the combined stresses and strains on the local ligaments, muscles and disc tissue during sagittal plane two-handed ...
Prolonged median sensory latency as a predictor of future carpal tunnel syndrome
(John Wiley & Sons, Inc., 2001-11)
The purpose of the study was to determine whether abnormal median sensory nerve conduction among asymptomatic workers was predictive of future symptoms suggestive of carpal tunnel syndrome (CTS). This was a prospective ...
Validation of a biodynamic model of pushing and pulling
(Elsevier, 1991)
Pushing and pulling during manual material handling can increase the compressive forces on the lumbar disc region while creating high shear forces at the shoe-floor interface. A sagittal plane dynamic model derived from ...
The use of a mixed Weibull model in occupational injury analysis
(Elsevier, 1986-02)
Chung, M.K., Wu, S-C.H. and Herrin, G.D. (1986). The use of a mixed Weibull model in occupational injury analysis. Journal of Occupational Accidents, 7: 239-250.This article describes a mixed Weibull model which is proposed ...
Vibration-induced muscle fatigue, a possible contribution to musculoskeletal injury
(Springer-Verlag, 2002-11)
Localized muscle fatigue resulting from 30-min sustained and intermittent grip exertions of 5% maximal voluntary contraction (MVC) with and without hand-vibration exposure (10 Hz, 7 mm displacement amplitude) was investigated. ...
A method of measuring fingertip loading during keyboard use
(Elsevier, 1994-08)
A single keycap on a standard alphanumeric computer keyboard was instrumented with a piezoelectric load cell and the fingertip motion was recorded with a high-speed video motion analysis system. Contact force histories ...
Median mononeuropathy among active workers: Are there differences between symptomatic and asymptomatic workers?
(John Wiley & Sons, Inc., 1998-04)
The objective was to determine whether symptomatic workers with an abnormal sensory nerve conduction study consistent with carpal tunnel syndrome differed, in terms of electrophysiologic measures, psychosocial, demographic, ...
A comparison of three dimensional maximum reach estimation techniques
(Elsevier, 1980)
Spline, periodic spline and spherical harmonic maximum reach estimation procedures are compared and evaluated based on ease of usage, estimation error and bias. The comparison indicates that each method provides comparable ...
Test-retest reliability of the Upper Extremity Questionnaire among keyboard operators * Website for University of Michigan Upper Extremity Questionnaire: http://rercdev.engin.umich.edu/jobdatabase/ †
(John Wiley & Sons, Inc., 2001-12)
Background Questionnaires are often used in research among workers although few have been tested in the working population. The Upper Extremity Questionnaire is a self-administered questionnaire designed for epidemiological ...
