It is characterized by substantial interindividual variability in muscle activation patterns, lumbo-pelvic coordination, and movement strategies. Although exercise is widely recommended as a first-line intervention and its clinical benefits are well established, the biomechanical mechanisms underlying functional improvement remain fragmented in the literature and are rarely synthesized quantitatively.

This dissertation conducted a systematic review with meta-analysis to investigate the biomechanical effects of exercise-based interventions in individuals with CNLBP. A total of 39 studies were included and …

Understanding Motor Competence In Autism And Developmental Coordination Disorder: From Everyday Performance To Underlying Postural Control Mechanisms, Crystal E. Alvarez

Kinesiology Dissertations

Motor competence plays a foundational role in children’s participation, physical activity, adaptive behavior, and overall quality of life. Although motor difficulties are highly prevalent in autism spectrum disorder (autism) and developmental coordination disorder (DCD), these challenges are frequently under-identified and insufficiently characterized, particularly in autistic populations. Existing research demonstrates substantial overlap in motor challenges across autism and DCD; however, relatively little work has integrated caregiver perceptions, standardized motor assessment, and mechanistic postural control measures within the same investigation. Therefore, the purpose of this dissertation was to examine motor competence and postural control in autistic children, children with DCD, and neurotypical …
