  • How Quantity and Quality of Brace Wear affect Brace Treatment Outcomes (Dec 2014)
    Principal Investigator: Edmond Lou
    The quantity and quality of brace usage are important factors in achieving successful brace treatment. The quantity of brace wear is the amount of brace wear time relative to the prescribed wear time; the quality of brace wear is the amount of time that the brace is worn at or above the prescribed tightness. The more time that brace was worn at the prescribed level; it more likely to have a better treatment result.

  • Markerless Surface Topography Measurements (September 2014)
    Principal Investigator: S. Adeeb
    Using data from the project above, a novel asymmetry analysis strategy was proposed to complete surface topography analyses without the use of markers placed on bony landmarks of patient achieving a high reliability. This asymmetry analysis allowed to categorize patients with scoliosis according to their curve severity, predict the location of curve apices and develop classification trees predicting whether patients experienced scoliosis curve progression over a one year interval.
  • The Schroth Exercise Trial for Scoliosis Pilot Study (SETS) (August 2014)
     Principal Investigator: Eric Parent
    This study was conducted to determine the feasibility and provide effect estimates for adding a 6-month program of Schroth scoliosis-specific exercises to the standard of care in patients with adolescent idiopathic scoliosis compared to standard care. Schroth exercises have positive effects on the Cobb angle, back muscle endurance time, pain, self-image and surface topography measurements.
  • Full Torso Surface Topography Measurements for the Management of Scoliosis: Reliability, Responsiveness and Correlations with Radiographic Measures of Curve Severity (January 2014)
    Principal Investigator: Eric Parent
    This study determined the intra-rater, inter-rater and test-retest reliability of marker-based torso shape deformity measurements obtained using full-torso compared to back-only parameters. The validity of measurements was compared to radiographic measurements. Curve type affect the strength of association between surface measurements and radiographic measurements. The ability of parameters to detect changes over time was compared by correlations with radiographic changes and using standardized response mean estimates to identify the best surface topography parameters.
  • Reliability of an Algorithm to Guide Schroth Curve Type Classification (August 2014)
    Principal Investigator: Eric Parent
    We developed an algorithm to guide the Schroth curve type classification of patients with adolescent idiopathic scoliosis. The algorithm was taught online to 10 certified Schroth therapist internationally using a web site. We determined that interrater reliability was adequate using the algorithm among therapists reporting full understanding following education procedures.

  • Fatigability of Paraspinal Muscles in Patients with Adolescents Idiopathic Scoliosis and Matched Controls during Side Planks (August 2014)
    Principal Investigator: Eric Parent
    Patients had longer hold time on their convex side and controls during the right side plank. Controls demonstrated more EMG fatigue quantified by the slope of the median frequency. Both groups demonstrated more EMG fatigue during the convex/ right side planks and more fatigue at the upper end vertebra level. Both groups demonstrated more fatigue at the lower end vertebra during the Sorensen back extension test. High variability in fatigue indicators was observed for the side-plank tasks possibly preventing detection of additional differences between groups.

  • A Systematic Review of the Impairments Affecting Paraspinal Muscles in Patients with Adolescent Idiopathic Scoliosis (August 2014)
    Principal Investigator: Eric Parent
    Our review included 24 papers. Evidence is limited on objectives pursued in this review due to the low quality of the evidence available and to the lack of research about muscle impairments in scoliosis. No studies were found on endurance deficits in AIS. Research is needed using large, homogenous samples allowing for a comparison between curve types and examining relation to the risk of progression.
