Jean-Philippe Pialasse, Pierre Mercier, Martin Descarreaux, Martin Simoneau

Gait & Posture > 2017 > 57 > C > 124-129

This work identifies, among adolescents with idiopathic scoliosis, those demonstrating impaired sensorimotor control through a classification procedure comparing the amplitude of their vestibular-evoked postural responses. The sensorimotor control of healthy adolescents (n=17) and adolescents with idiopathic scoliosis (n=52) with either mild (Cobb angle≥15° and ≤30°) or severe (Cobb angle >30°)...

Change in the natural head-neck orientation momentarily altered sensorimotor control during sensory transition

Isabelle Xu, Simon Laurendeau, Normand Teasdale, Martin Simoneau

Gait & Posture > 2017 > 53 > C > 80-85

Achilles tendon vibration generates proprioceptive information that is incongruent with the actual body position; it alters the perception of body orientation leading to a vibration-induced postural response. When a person is standing freely, vibration of the Achilles tendon shifts the internal representation of the verticality backward thus the vibration-induced postural response realigned the whole...

Sensorimotor Control Impairment in Young Adults With Idiopathic Scoliosis Compared With Healthy Controls

Jean-Philippe Pialasse, Pierre Mercier, Martin Descarreaux, Martin Simoneau

Journal of Manipulative and Physiological Therapeutics > 2016 > 39 > 7 > 473-479

It has been hypothesized that the impaired sensorimotor control observed in adolescents with idiopathic scoliosis (IS) may be related more to the onset of scoliosis than to the maturation of sensory systems or sensorimotor control mechanisms. The objective of this study was to assess sensorimotor control in adults diagnosed with IS in adolescence versus healthy controls.The study included 20 young...

Sensory reweighting is altered in adolescent patients with scoliosis: Evidence from a neuromechanical model

Jean-Philippe Pialasse, Martin Descarreaux, Pierre Mercier, Martin Simoneau

Gait & Posture > 2015 > 42 > 4 > 558-563

Idiopathic scoliosis is the most frequent spinal deformity in adolescence. While its aetiology remains unclear, impairments in balance control suggest a dysfunction of the sensorimotor control mechanisms. The objective of this paper is to evaluate the ability of patients with idiopathic scoliosis to reweigh sensory information. Using a neuromechanical model, the relative sensory weighting of vestibular...

Reduced plantar sole sensitivity induces balance control modifications to compensate ankle tendon vibration and vision deprivation

Maxime Billot, Grant A Handrigan, Martin Simoneau, Normand Teasdale

Journal of Electromyography and Kinesiology > 2015 > 25 > 1 > 155-160

The aim of this study was to investigate if sensory reweighting occurred to control balance when the sensitivity of the plantar sole is reduced using cooling. To address this question, visual information was manipulated and/or ankle proprioception was altered by Achilles tendon vibration. It was expected that Achilles tendon vibration and vision deprivation would induce greater center of pressure...

Balance control impairment in obese individuals is caused by larger balance motor commands variability

Martin Simoneau, Normand Teasdale

Gait & Posture > 2015 > 41 > 1 > 203-208

It is acknowledged that various factors impaired balance control. Among them, heavy body weight is associated with poor balance control because the location of the center of mass is further away from the ankle joint. Thus, a larger active ankle torque is required to counter the greater gravitational torque. Because balance motor commands have signal-dependent noise whose standard deviation increases...

Balance control interferes with the tracing performance of a pattern with mirror-reversed vision in older persons

Léandre Gagné Lemieux, Martin Simoneau, Jean-François Tessier, Maxime Billot, more

AGE > 2014 > 36 > 2 > 823-837

When tracing a template with mirror-reversed vision (or distorted vision), the sensory information arising from the movement does not match the expected sensory consequences. In such situations, participants have to learn a new visuomotor mapping in order to trace the template with an accuracy and speed approaching that observed when tracing with direct vision. There are several suggestions that such...

Estimate of body motion during voluntary body sway movements

Étienne Couture, Martin Simoneau

Gait & Posture > 2014 > 39 > 1 > 70-74

Balance control can be interpreted as a combination of state feedback control with optimal state estimation. In this framework, state estimation uses an internal model of body and sensor dynamics to process sensory information and determine body orientation. The aim of this study was to assess the ability of the brain to create accurate state estimation when the congruence between sensory information...

Quantifying forearm and wrist joint power during unconstrained movements in healthy individuals

Diana Castillo Flores, Simon Laurendeau, Normand Teasdale, Martin Simoneau

Journal of NeuroEngineering and Rehabilitation > 2014 > 11 > 1 > 1-7

Background Wrist movement-related injuries account for a large number of repetitive motion injuries. Remarkably little, if any, empirical data exist to quantify the impact of neuromuscular disorders affecting the wrist or to validate the effectiveness of rehabilitation training programs on wrist functions. The aim of this project was to develop a biomechanical model for quantifying wrist and forearm...

Lower-Limb Power cannot be Estimated Accurately from Vertical Jump Tests

Jean-François Tessier, Fabien-A Basset, Martin Simoneau, Normand Teasdale

Journal of Human Kinetics > 2013 > 38 > 5-13

The countermovement jump test is often adopted to monitor lower-limb power of an individual. Despite several studies on the validity of this test, there is still a need to determine the minimal difference needed to be confident that a difference in power between two individuals is present or that a true change in the performance of an individual has occurred. In this study, power was measured from...

Is abnormal vestibulomotor responses related to idiopathic scoliosis onset or severity?

Jean-Philippe Pialasse, Simon Laurendeau, Martin Descarreaux, Jean Blouin, more

Medical Hypotheses > 2013 > 80 > 3 > 234-236

Results from several studies have suggested that brainstem dysfunction occurs more often in adolescent with idiopathic scoliosis compared to healthy individuals. The vestibular nuclei occupy a prominent position in the brainstem. Because the lateral vestibulospinal tract controls axial muscles, alteration in the brainstem during body growth (i.e., preadolescent and adolescent period) may translate...

The impact of obesity on balance control in community-dwelling older women

Maxime Dutil, Grant A. Handrigan, Philippe Corbeil, Vincent Cantin, more

AGE > 2013 > 35 > 3 > 883-890

Older individuals have impaired balance control, particularly those that are frail and/or have sensory deprivations. Obese individuals show faster body sway during upright stance than normal weight individuals, suggesting that they also have difficulty controlling balance even if they do not have the same sensory issues as the older people. Therefore, the objective of this study was to examine if...
