    A systematic review of the effects of single-event multilevel surgery on gait parameters in children with spastic cerebral palsy
    (Public Library of Science, 2016) Lamberts, Robert P; Burger, Marlette; Toit, Jacques du; Langerak, Nelleke G
    BACKGROUND: Three-dimensional gait analysis (3DGA) is commonly used to assess the effect of orthopedic single-event multilevel surgery (SEMLS) in children with spastic cerebral palsy (CP). Purpose The purpose of this systematic review is to provide an overview of different orthopedic SEMLS interventions and their effects on 3DGA parameters in children with spastic CP. METHODS: A comprehensive literature search within six databases revealed 648 records, from which 89 articles were selected for the full-text review and 24 articles (50 studies) included for systematic review. The Oxford Centre for Evidence-Based Medicine Scale and the Methodological Index for Non-Randomized Studies (MINORS) were used to appraise and determine the quality of the studies. RESULTS: Except for one level II study, all studies were graded as level III according to the Oxford Centre for Evidence-Based Medicine Scale. The MINORS score for comparative studies (n = 6) was on average 15.7/24, while non-comparative studies (n = 18) scored on average 9.8/16. Nineteen kinematic and temporal-distance gait parameters were selected, and a majority of studies reported improvements after SEMLS interventions. The largest improvements were seen in knee range of motion, knee flexion at initial contact and minimal knee flexion in stance phase, ankle dorsiflexion at initial contact, maximum dorsiflexion in stance and in swing phase, hip rotation and foot progression angles. However, changes in 3DGA parameters varied based on the focus of the SEMLS intervention. DISCUSSION: The current article provides a novel overview of a variety of SEMLS interventions within different SEMLS focus areas and the post-operative changes in 3DGA parameters. This overview will assist clinicians and researchers as a potential theoretical framework to further improve SEMLS techniques within different SEMLS focus groups. In addition, it can also be used as a tool to enhance communication with parents, although the results of the studies can't be generalised and a holistic approach is needed when considering SEMLS in a child with spastic CP.

    The identification of gait asymmetry in children with juvenile idiopathic arthritis
    (2025) Mpaka, Lindiwe; Kroff, Jacolene; Atterbury, Elizma
    Background: Gait abnormalities are common in children with JIA, and early detection is crucial to reduce walking disability, which is a significant aspect of daily life. Analyzing gait in this population provides vital information about joint issues and walking patterns, guiding treatment goals. Addressing gait asymmetry can enhance a child's functional abilities, participation in activities, and overall quality of life. Purpose: To determine the incidence of gait asymmetry in children with JIA and to further determine the association between gait asymmetry and disease severity and functional capacity Study design: Cross-sectional Observational study. Methods: A total number of 14 children between 6-16 years of age (accompanied by their parents) that are diagnosed with JIA, were recruited. They were recruited between April and October 2023 at Tygerberg Hospital, Bellville, Cape Town during routine medical check-ups. The 6MWT was used to assess gait-related variables using the APDM wearable Technologies® incorporated within the Mobility Lab software package. We focused on the examination of five gait parameters related to the lower limbs: 1) Gait cycle duration, 2) gait speed, 3) time in stance phase, 4) stride length, and 5) time in swing phase. The test was administered in a 25 meters walkway, which was measured using a tape measurer, two cones were placed on each end, one at the beginning and one cone at the end of the distance. Results: We found a statistically significant difference in gait speed and stride length (p=0.031 and p=0.046, respectively) for the total group, considering left and right leg. Gait asymmetry was found in 8 of 14 participants when the effect size was calculated. No significant differences were found when comparing four of the gait variables between the asymmetry and no asymmetry groups. However, a statistically significant difference was observed in stride length (p = 0.04 left and p = 0.03 right) in the asymmetry and no asymmetry group. There was no statistical significance between the disease activity and the asymmetry group (p = 0.627). No statistically significant difference was observed in the total distance achieved in both the asymmetry and no asymmetry group on the 6MWT. Conclusion: Our study underscores the significant impact of gait speed and stride length on gait asymmetry in children with JIA. These gait parameters exhibited the greatest discrepancies among participants, with stride length closely associated with gait asymmetry and gait speed significantly correlated with the total distance achieved during the 6MWT. These findings suggest that both stride length and gait speed are critical factors in understanding gait asymmetry and the functional limitations experienced by children with JIA.
