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

Pialasse JP, Descarreaux M, Mercier P, Simoneau M Gait Posture 2015 Sep; PMID: 26371828 Abstract 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… Read More »

Effect of bracing or surgical treatments on balance control in idiopathic scoliosis: three case studies

Pialasse JP, Simoneau M J Can Chiropr Assoc 2014 Jun;58(2):131-40 PMID: 24932017 Abstract Scoliosis is the most frequent spinal deformity among adolescents. In 80 % of cases, it is defined as idiopathic as no individual cause has been identified. However, several factors linked to Adolescent Idiopathic Scoliosis (AIS) have been identified and are under investigation.… Read More »

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

Pialasse JP, Laurendeau S, Descarreaux M, Blouin J, Simoneau M Med. Hypotheses 2013 Mar;80(3):234-6 PMID: 23265357 Abstract 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… Read More »

Load and speed effects on the cervical flexion-relaxation phenomenon

Pialasse JP, Lafond D, Cantin V, Descarreaux M BMC Musculoskelet Disord 2010;11:46 PMID: 20219131 Abstract BACKGROUND: The flexion-relaxation phenomenon (FRP) represents a well-studied neuromuscular response that occurs in the lumbar and cervical spine. However, the cervical spine FRP has not been investigated extensively, and the speed of movement and loading effects remains to be characterized.… Read More »

Kinematic and electromyographic parameters of the cervical flexion-relaxation phenomenon: the effect of trunk positioning

Pialasse JP, Dubois JD, Choquette MH, Lafond D, Descarreaux M Ann Phys Rehabil Med 2009 Feb;52(1):49-58 PMID: 19419658 Abstract BACKGROUND: The cervical flexion-relaxation phenomenon (FRP) is a neck extensor myoelectric “silence” that occurs during complete cervical flexion. The aim of this study was to assess the presence of this phenomenon in the cervical region and… Read More »
