Contessa P, Nawab S, De Luca C
Annu Int Conf IEEE Eng Med Biol Soc
. 2012 Jan;
2011:4072-5.
PMID: 22255235
A model for the simulation of motoneuron firing behavior and muscle force during sustained constant-force isometric contractions was developed. It provides a non-linear relationship between the excitation to the motoneuron...

De Luca C, Kline J
J Neural Eng
. 2011 Dec;
9(1):016007.
PMID: 22183300
We investigated the relationships of the firing rate and maximal recruitment threshold of motoneurons recorded during isometric contraction with the number of spindles in individual muscles. At force levels above...

Masuda T, De Luca C
J Electromyogr Kinesiol
. 2010 Sep;
1(2):116-23.
PMID: 20870501
The average muscle fiber conduction velocity (CV) measured with multicontact surface electrodes has been reported to increase with the contraction force. To understand this behavior better, we studied the relationship...

Masuda T, De Luca C
J Electromyogr Kinesiol
. 2010 Aug;
1(1):75-80.
PMID: 20719598
A technique was developed to identify the propagation pattern of high-threshold motor unit action potentials (MUAPs) in human skeletal muscles. A linear surface array and a selective needle electrode were...

Sabbahi M, De Luca C
J Electromyogr Kinesiol
. 2010 Aug;
1(1):41-8.
PMID: 20719594
Application of a topical anesthetic on the skin of the upper and lower limbs of chronic stroke and head-trauma patients induced considerable improvement in limb mobility within 30 min. We...

Roy S, De Luca G, Cheng M, Johansson A, Gilmore L, De Luca C
Med Biol Eng Comput
. 2007 Apr;
45(5):447-57.
PMID: 17458582
This study compared the performance of surface electromyographic (sEMG) sensors for different detection conditions affecting the electro-mechanical stability between the sensor and its contact with the skin. These comparisons were...

Agarabi M, Bonato P, De Luca C
Conf Proc IEEE Eng Med Biol Soc
. 2007 Feb;
2004:2450-3.
PMID: 17270768
Computer users who experience repetitive wrist movements and awkward hand positions are prone to developing upper extremity disorders. Manufacturers have designed various ergonomic mice in response to complaints of pain...

Westad C, Westgaard R, De Luca C
J Physiol
. 2003 Oct;
552(Pt 2):645-56.
PMID: 14561844
The activity pattern of low-threshold human trapezius motor units was examined in response to brief, voluntary increases in contraction amplitude ('EMG pulse') superimposed on a constant contraction at 4-7 %...

Bonato P, Roy S, Knaflitz M, De Luca C
IEEE Trans Biomed Eng
. 2001 Jul;
48(7):745-53.
PMID: 11442286
The time-dependent shift in the spectral content of the surface myoelectric signal to lower frequencies has proven to be a useful tool for assessing localized muscle fatigue. Unfortunately, the technique...

Westgaard R, De Luca C
J Neurophysiol
. 2001 Apr;
85(4):1777-81.
PMID: 11287499
The firing pattern of low-threshold motor units was examined in the human trapezius and first dorsal interosseous (FDI) muscles during slowly augmenting, low-amplitude contractions that were intended to mimic contractile...
