Ultrasound Imaging Analysis of the Lumbar Multifidus Muscle Echo Intensity: Intra-Rater and Inter-Rater Reliability of a Novice and an Experienced Rater

Author(s): Fortin M; Rosenstein B; Levesque J; Nandlall N;

Background and Objectives: Ultrasound echo intensity (EI) of the lumbar multifidus muscle (LMM) could offer valuable insights regarding muscle quality in people with low back pain (LBP). However, whether the rater's experience noticeably influences the ...

The effects of combined motor control and isolated extensor strengthening versus general exercise on paraspinal muscle morphology and function in patients with chronic low back pain: a randomised controlled trial protocol

Author(s): Fortin M; Rye M; Roussac A; Naghdi N; Macedo LG; Dover G; Elliott JM; DeMont R; Weber MH; Pepin V; ...

Background: Exercise is a common approach for the management of patients with chronic non-specific low back pain (LBP). However, there is no clear mechanistic evidence or consensus on what type of ...

How cerebral cortex protects itself from interictal spikes: The alpha/beta inhibition mechanism

Author(s): Pellegrino G; Hedrich T; Sziklas V; Lina JM; Grova C; Kobayashi E;

Interactions between interictal epileptiform discharges (IEDs) and distant cortical regions subserve potential effects on cognition of patients with focal epilepsy. We hypothesize that "healthy" brain areas at a distance from the epileptic focus may respond ...

Association Between Pain Catastrophizing and Pain and Cardiovascular Changes During a Cold-Pressor Test in Athletes

Author(s): Lentini M; Scalia J; Lebel FB; Touma F; Jhajj A; Darlington PJ; Dover G;

Context: Athletes are often exposed to pain due to injury and competition. Using preliminary evidence, researchers have shown that cardiovascular measures could be an objective measure of pain, but the cardiovascular response can be influenced by psychologi ...

Weight bias and support of public health policies

Author(s): Edache IY; Kakinami L; Alberga AS;

Objectives: Public health policies have been proposed to help address prevalent Canadian obesity rates. Along with the increase in obesity prevalence, explicit weight bias is also rampant in Western society. This paper aimed to assess the association betwee ...

Putting ATM to BED: How Adipose Tissue Macrophages Are Affected by Bariatric Surgery, Exercise, and Dietary Fatty Acids

Author(s): Turner L; Santosa S;

With increasing adiposity in obesity, adipose tissue macrophages contribute to adipose tissue malfunction and increased circulating proinflammatory cytokines. The chronic low-grade inflammation that occurs in obesity ultimately gives rise to a state of meta ...

White matter microstructural changes in short-term learning of a continuous visuomotor sequence

Author(s): Tremblay SA; Jäger AT; Huck J; Giacosa C; Beram S; Schneider U; Grahl S; Villringer A; Tardif CL; Bazin PL; Steele CJ; Gauthier CJ; ...

Efficient neural transmission is crucial for optimal brain function, yet the plastic potential of white matter (WM) has long been overlooked. Growing evidence now shows that modifications to axons ...

Signal-mediated localization of Candida albicans pheromone response pathway components

Author(s): Costa ACBP; Omran RP; Law C; Dumeaux V; Whiteway M;

Candida albicans opaque cells release pheromones to stimulate cells of opposite mating type to activate their pheromone response pathway. Although this fungal pathogen shares orthologous proteins involved in the process with Saccharomyces cerevisiae, the pa ...

A comparison of physical exercise and cognitive training interventions to improve determinants of functional mobility in healthy older adults

Author(s): Pothier K; Vrinceanu T; Intzandt B; Bosquet L; Karelis AD; Lussier M; Vu TTM; Nigam A; Li KZH; Berryman N; Bherer L; ...

Objectives: Mobility is a complex but crucial clinical outcome in older adults. Past observational studies have highlighted that cardiorespiratory fitness (CRF), energy cost of walking (ECW), and c ...

Deconvolution of hemodynamic responses along the cortical surface using personalized functional near infrared spectroscopy

Author(s): Machado A; Cai Z; Vincent T; Pellegrino G; Lina JM; Kobayashi E; Grova C;

In functional near infrared spectroscopy (fNIRS), deconvolution analysis of oxy and deoxy-hemoglobin concentration changes allows estimating specific hemodynamic response functions (HRF) elicited by neuronal activity, taking advantage of the fNIRS excellent ...

Multimodal 3D ultrasound and CT in image-guided spinal surgery: public database and new registration algorithms

Author(s): Masoumi N; Belasso CJ; Ahmad MO; Benali H; Xiao Y; Rivaz H;

Purpose: Accurate multimodal registration of intraoperative ultrasound (US) and preoperative computed tomography (CT) is a challenging problem. Construction of public datasets of US and CT images can accelerate the development of such image registration tec ...

X-Vectors: New Quantitative Biomarkers for Early Parkinson's Disease Detection From Speech

Author(s): Jeancolas L; Petrovska-Delacrétaz D; Mangone G; Benkelfat BE; Corvol JC; Vidailhet M; Lehéricy S; Benali H; ...

Many articles have used voice analysis to detect Parkinson's disease (PD), but few have focused on the early stages of the disease and the gender effect. In this article, we have adapted the la ...
