    Background: Children with juvenile idiopathic arthritis (JIA) exhibit gait abnormalities, postural instability, and compensatory movement strategies due to joint pain, inflammation, and reduced neuromuscular control. These alterations negatively affect functional mobility and movement efficiency. Although gait retraining is commonly recommended in rehabilitation, objective evidence on its short-term biomechanical effects remains limited. This study aimed to evaluate the immediate impact of a single-session standardized movement training intervention on gait biomechanics in children with JIA. Methods: Seventeen children with JIA underwent pre-post gait assessments using the Xsens MVN Awinda wearable motion capture system. The intervention focused on step symmetry, stride length, heel-toe progression, and upright trunk posture, delivered by an experienced physiotherapist following a standardized protocol. Scalar kinematic outcomes were analyzed using paired statistical tests, and time-normalized kinematic waveforms were compared with healthy reference data from 25 age-matched participants derived from the COMPWALK-ACL dataset. Results: Significant improvements were observed in multiple gait parameters following the intervention. Trunk lateral lean decreased significantly (p = 0.0002; d = -1.35), indicating enhanced postural stability. Significant changes were also found in ankle dorsiflexion-plantarflexion (p = 0.0081; d = 0.83) and knee flexion-extension (p = 0.0252; d = 0.68). Waveform analyses showed increased similarity to healthy patterns, particularly in trunk and knee kinematics. Spatiotemporal parameters reflected a slower, more controlled gait pattern, with increased stride time and stance duration. Conclusions: A single session of standardized movement training can produce immediate improvements in gait biomechanics in children with JIA, especially in trunk control and lower-limb kinematics. Wearable motion analysis provides a sensitive tool for detecting these short-term adaptations and supports the inclusion of structured movement training in pediatric JIA rehabilitation.

    Effects of an Adapted Dance Exercise Program on Trunk Control, Balance and Functional Mobility in Children and Adolescents with Cerebral Palsy: Randomized Controlled Study
    (Taylor & Francis inc, 2025) Yekdaneh, Asena; Arman, Nilay
    Aims: The study aimed to investigate whether an 8-week adapted dance exercise program (ADEP), delivered in addition to conventional physiotherapy, would improve trunk control, balance, functional mobility, and quality of life (QoL) in children and adolescents with cerebral palsy (CP) compared with conventional physiotherapy alone. Methods: Thirty participants with CP (Gross Motor Function Classification System Level I - II) were randomly assigned to the ADEP group (n = 15) or the control group (n = 15). Both groups received conventional physiotherapy, while the ADEP group additionally performed physiotherapist-choreographed dance exercises accompanied by music, twice a week for 8 weeks. Outcomes included the Trunk Control Measurement Scale (TCMS) for trunk control, the Pediatric Balance Scale (PBS) for balance, the Timed Up and Go (TUG) for functional mobility, and the Pediatric Outcomes Data Collection Instrument (PODCI) for QoL. Results: The ADEP group showed significantly greater improvements than the control group in TCMS-Total (Delta = 10.53 vs 3.50, p < .001), TCMS-selective motor control (Delta = 6.00 vs 1.42, p < .001), TCMS-dynamic sitting balance (Delta = 7.53 vs 2.28, p < .001), and PODCI-Global scores (Delta = 4.61 vs -1.71, p < .001). Both groups improved in PBS and TUG, but between-group differences were not significant. Effect sizes indicated large improvements in trunk control in favor of the ADEP group. Conclusions: An 8-week ADEP program, when combined with conventional physiotherapy, produced clinically meaningful gains in trunk control and QoL in children and adolescents with CP. These findings support the use of dance-based rehabilitation as a feasible and engaging adjunct to physiotherapy.
