Suggested Replacements for Trigno™ Wireless Standard Sensor (EMG + 3D ACC)

July 12th, 2017|Categories: Blogs, Support|

Over the better part of a decade, Delsys has advanced EMG sensor technology by continuously expanding our Trigno™ Wireless product line to accommodate the intricate needs of our customers. As a result of our advancement, we will be retiring our [...]

Extreme Learning Machines for Real-Time Myoelectric Control

September 29th, 2016|Categories: Blogs|

Myoelectric signals are rich sources of information about human movement control. They are also easily accessible, making them appealing for controlling devices like prosthetics, orthotics, and exoskeletons. However, the variability of the EMG signal and required processing time make it [...]

Should Basketball Players Tape Their Ankles?

An interdisciplinary group of researchers from universities in Australia and the US, including Matthew Jeffriess from University of Technology Sydney and Dr. Robert Lockie from California State University, Northridge, teamed up to investigate whether ankle taping has an effect [...]

Gender and Psychological Factors on Pain Perception and Muscle Activity: an Induced-Pain Study of Anterior and Posterior Masseter Muscles

December 1st, 2015|Categories: Blogs|

Chronic orofacial muscle pain imposes considerable personal and economic burdens for a broad spectrum of the general population. It is the chief complaint of the more than 5-10% of the US population with temporomandibular joint and muscle disorder (TMJD). Despite [...]

Innovative Bionic Hand Provides Amputees with Sense of Touch

July 20th, 2015|Categories: Blogs, Research Videos|

Researchers at the University of Newcastle are undertaking an ambitious project to provide bionic hands with the sense of touch. The investigators involved in this government-funded, £1.4 million project are aiming to design a prosthesis that establishes two-way communications between [...]

The Advantage of Delsys dEMG

July 10th, 2015|Categories: Blogs|Tags: |

A critical review by De Luca CJ and Kline JC June 2015 Technology for decomposing the EMG signal into individual motor unit action potentials (MUAPs) was introduced by us three decades ago (LeFever and De Luca, 1982). The Delsys [...]

The Onion-Skin Scheme: A Motor Unit Firing Scheme with Evolutionary Benefits

July 1st, 2015|Categories: Blogs|Tags: |

How are motor units controlled during voluntary contractions? This question has been a subject of debate for several decades amongst the neurophysiology community. A recent simulation study by Dr. Carlo J. De Luca and Dr. Paola Contessa1 compared two opposing [...]

Motor Adaptation for EMG-Powered Prostheses: A New Strategy

March 30th, 2015|Categories: Blogs|

In an effort to improve prosthesis design, researchers from Northwestern University and the Rehabilitation Institute of Chicago investigated how EMG control of a virtual computer interface affects an individual's motor adaptation. Current EMG-powered prostheses have often struggled to replicate natural [...]

SigMax: A Statistically Sound Approach to Explaining Motor Unit Synchronization

February 9th, 2015|Categories: Blogs|Tags: |

For several decades, studies throughout the motor control literature have claimed synchronization of motor unit firings result from common presynaptic branches, or “common inputs” shared by the motoneurons. However, the methods that support this notion have lacked necessary statistical rigor [...]
