OBJECTIVE To explore the mechanism of lower extremity dysfunction of cerebral palsy (CP) children through muscle synergy analysis. APPROACH Twelve CP children were involved in this study, ten adults (AD) and eight typically developed (TD) children were recruited as a control group. Surface electromyographic (sEMG) signals were collected bilaterally from eight lower limb muscles of the subject...

BACKGROUND A deep characterization of neurological patients is a crucial step for a detailed knowledge of the pathology and maximal exploitation and customization of the rehabilitation therapy. The muscle synergies analysis was designed to investigate how muscles coactivate and how their eliciting commands change in time during movement production. Few studies investigated the value of muscle s...

Production of voluntary movements relies critically on the functional integration of several motor cortical areas, such as the primary motor cortex, and the spinal circuitries. Surprisingly, after almost 40 years of research, how the motor cortices specify descending neural signals destined for the downstream interneurons and motoneurons has remained elusive. In light of the many recent experim...

Combinatorial auctions allow bidding for combinations of items (package bids) and are a useful tool when complementarities/synergies among sale objects are present. In such cases, package biding improves economic efficiency by helping bidders win packages that capture the value added due to synergies. The revenue of the seller may also increase as a result. At the same time, when synergies are ...

A long standing hypothesis in the neuroscience community is that the central nervous system (CNS) generates the muscle activities to accomplish movements by combining a relatively small number of stereotyped patterns of muscle activations, often referred to as "muscle synergies." Different definitions of synergies have been given in the literature. The most well-known are those of synchronous, ...

The purpose of the present study was to determine whether muscle synergies are constrained by changes in the mechanics of pedaling. The decomposition algorithm used to identify muscle synergies was based on two components: "muscle synergy vectors," which represent the relative weighting of each muscle within each synergy, and "synergy activation coefficients," which represent the relative contr...

The purpose of this study was to evaluate the muscle synergies during Wingate anaerobic rowing test of collegiate rowers and physically active individuals who were not specifically trained in rowing. As a power-endurance sport, high anaerobic capacity is one of the determinants of rowing performance. Due to the close link that exists between the state of energy supply and types of muscle fibers...
