Most clinical gait laboratories utilize the conventional gait model or one of its variants for planning and evaluating treatment in children with cerebral palsy (CP). Estimation of the hip joint center (HJC) is identified as a major source of error that can influence the model outcomes [Peters2010]. Predictive and functional approaches have been proposed in the literature for HJC estimation. Functional approaches are recommended for subjects with adequate hip range of motion (ROM), while predictive approaches are suggested for subjects with limitations in hip ROM, such as children with CP [Kainz2015]. Because functional approaches require multiplane tasks like StarArc movement to calibrate it. Recently, Ravera and Peterson (2021) proposed a regularized version of the well-known symmetric center of rotation estimation method (SCoRE)[Erigh2006] that does not require additional movements for HJC estimation, called RSCoRE.Research question: Is it feasible to estimate the HJC in children with CP using RSCoRE without the need for additional functional calibration tasks?
