Purpose Full-time wearing of an orthopedic brace has demonstrated effectiveness in limiting curve progression in adolescents with idiopathic scoliosis. However, treatment adherence is challenging, with an average wearing time of 13 h/day. Despite this issue, barriers to brace adherence have rarely been studied. The aim of this study was to develop...

Background: Adolescent idiopathic scoliosis and its treatments can severely impact health-related quality of life. The Italian Spine Youth Quality of Life (ISYQOL) questionnaire, initially developed in Italian and tested on Italian people, was created to measure quality of life in young persons with spine changes. ISYQOL was created using the Rasc...

In a bimanual task, proprioception provides information about position and movement of upper arms. Developmental studies showed improvement of proprioceptive accuracy and timing adjustments of muscular events from childhood to adulthood in bimanual tasks. However, the cortical maturational changes related to bimanual coordination is not fully under...

The intervertebral efforts, i.e., forces and torques, during gait have been recognized as influencing the progression of scoliosis, due to the mechanical modulations according to the Hueter-Volkmann Law. Therefore, these efforts are key variables for posture correction and to control the progression of scoliosis. Using the intervertebral efforts du...

Adolescent idiopathic scoliosis (AIS) is a multifactorial disorder characterized by a tridimensional deformation of the spine. AIS pathophysiology is still unclear and its aetiology is unknown. Results from several studies revealed balance control alterations in adolescents with AIS suggesting cortical sensorimotor processing impairments. Studies a...

Introduction Several studies revealed balance control alterations in adolescents with idiopathic scoliosis (AIS) suggesting cortical sensorimotor processing impairments. This study aims at examining the cortical dynamics of sensorimotor information processing related to balance control in different sensory tasks in participants with AIS and in age-...

Objective: This study aims at examining the cortical dynamics of sensorimotor information processing related to balance control in participants with adolescent idiopathic scoliosis (AIS) and in age-matched controls (CTL). Methods: Cortical dynamics during standing balance control were assessed in 13 girls with AIS and 13 age-matched controls usi...

Introduction: Gait analysis has often been recognized as helpful for the therapeutic follow-up of adolescents with idiopathic scoliosis (IS). Methods: A multibody model of the human body was developed to display the intervertebral efforts along the spine of each adolescent with IS, and highlight the efforts that significantly differ from typical...

Background There is a lack of evidence-based quantitative clinical methods to adequately assess posture. Our team developed a clinical photographic posture assessment tool (CPPAT) and implemented this tool in clinical practice to standardize posture assessment. The objectives were to determine the level of acceptance of the CPPAT and to document pr...

Abstract Background Global postural re-education (GPR) is a physiotherapy treatment approach for pediatric idiopathic scoliosis (IS), where the physiotherapist qualitatively assesses scoliotic curvature reduction potential (with a manual correction) and patient’s ability to self-correct (self-correction). To the author’s knowledge, there are no stu...

Background context: Posture changes are a major consequence of IS (IS). Posture changes can lead to psychosocial and physical impairments in adolescents with IS. Therefore, it is important to assess posture but the test-retest reliability of posture measurements still remains unknown in this population. Purpose: The primary objective was to dete...

During action, Anticipatory Postural Adjustments (APAs) cancel the consequences of a movement on postural stabilization. Their muscular expression is characterized by early changes in the activity of the postural muscles, before the movement begins. To explore the mechanisms enabling the acquisition of APAs, a learning paradigm was designed in whic...

Distribution of the inhibition onset values across trials in the learning situation. The number of trials was reported across a window starting at -115ms and ending at +78ms, with a 2-ms step. The limits (mean ± standard deviation) of the time-windows where the EMG responses occurred in the voluntary and imposed unloading situations are also indica...

Distribution of the EMG pattern through subjects. The number of trials was reported for each subject during each series of the learning situation: for (A) the non-identifiable trials, (B) the single inhibition pattern and (C) the double inhibition pattern. (TIFF)

Background context: Trunk imbalance (i.e. frontal trunk shift measured with a plumbline from C7 to S1) is part of the clinical evaluation in adolescent idiopathic scoliosis (AIS) but its prevalence and relationship with scoliosis, back pain and health related factors is not well documented. Purposes: Principal objectives are to document trunk im...

Background: Back pain has often been associated with adolescent idiopathic scoliosis (AIS), which is a three-dimensional deviation of the vertebral column. In adolescents, chronic pain appears to be a predictor of health care utilization and has a negative impact on physical, psychological and family well-being. Back pain in this population tends t...

Background Correction of posture is an important goal of physiotherapy interventions in persons with idiopathic scoliosis (IS) to prevent scoliosis progression and to reduce morphologic deformities and their impact on quality of life. Currently, there are no clinical tools that globally quantify changes in posture attributable to scoliosis progress...

ABSTRACT The objective of this study was to explore whether differences in standing and sitting postures of youth with idiopathic scoliosis could be detected from quantitative analysis of digital photographs. Standing and sitting postures of 50 participants aged 10-20-years-old with idiopathic scoliosis (Cobb angle: 15° to 60°) were assessed from d...

The aim of this study was to explore, during adolescence, alterations in the use of a sensori-motor representation as unveiled by the measurement of anticipatory postural control in a bimanual load-lifting task. We hypothesised that adolescence constitutes a period of refinement of anticipatory postural control due to on-going updates of the body s...

Background In the Global postural re-education (GPR) evaluation, posture alterations are associated with anterior or posterior muscular chain impairments. Our goal was to assess the reliability of the GPR muscular chain evaluation. Methods Design: Inter-rater reliability study. Fifty physical therapists (PTs) and two experts trained in GPR assesse...
