The effect of perspiration on the sEMG amplitude and power spectrum
21 May 2012
Mohammad Abdoli-Eramaki, Caroline Damecour, John Christenson, Joan Stevenson
Abstract: Sweat accumulation underneath surface EMG (sEMG) electrodes is a common problem in workplace studies which compromises electrode adherence to the skin as well as signal fidelity. In this stu...

Novel formulation of a double threshold algorithm for the estimation of muscle activation intervals designed for variable SNR environments
21 May 2012
G. Severini, S. Conforto, M. Schmid, T. D’Alessio
Abstract: The aim of this work is the development of an improved formulation of the double threshold algorithm for sEMG onset–offset detection presented by Bonato and co-workers. The original formulat...

The effect of changes in joint angle on the characteristics of physiological tremor
18 May 2012
Benoit Carignan, Jean-François Daneault, Christian Duval
Abstract: Introduction: Physiological tremor, as a whole, can be influenced by changes in muscle activity. However, the origin of low-frequency physiological tremor oscillations has yet to be conclusi...

Biomechanical and metabolic responses to seat-tube angle variation during cycling in tri-athletes
18 May 2012
Maria Cristina Bisi, Mattia Ceccarelli, Federico Riva, Rita Stagni
Abstract: One of the most physically demanding parts of triathlon is the transition from cycling to running. Many tri-athletes believe that increasing seat-tube angle (STA) can bring advantages in the...
