Effects of Progressive Neuromuscular Stabilization Exercises Versus Aerobic Exercises on Body Composition and Postural Balance in Children With Obesity

What this study is about

Introduction: Childhood obesity can impair postural control, balance, and motor skills, thereby limiting participation in physical activity. Aerobic exercise is widely used to improve cardiovascular fitness and support weight management in children with obesity. In recent years, however, Progressive Neuromuscular Stabilization (PNS) exercises, which aim to retrain the neuromuscular system, have been suggested to have beneficial effects on core stability, balance, and postural control. Technology-assisted exercise interventions may increase children's participation and enhance motivation throughout the rehabilitation process. This study aims to compare the effectiveness of technology-assisted PNS exercises with conventional aerobic exercise in children with obesity. Methods: This study will be conducted among children attending the Department of Pediatrics, Istanbul University-Cerrahpaşa who meet the eligibility criteria. Children aged 12-18 years with obesity will be recruited. Participants will be randomly allocated into three groups: the Aerobic Exercise (AE) group, the Progressive Neuromuscular Stabilization (PNS) group, and the Control group. Participants in the exercise groups will receive supervised exercise sessions twice weekly for 12 weeks in a clinical setting and will be instructed to perform home-based exercises on the remaining days. Home exercise programs will be delivered through the BeCure® mobile application, where exercise videos will be uploaded, and participants will be asked to perform progressively advancing exercises on a weekly basis. The control group will receive a single session of exercise counseling. Outcome assessments will be performed before and after the intervention. Sample Size: The sample size was calculated using G\*Power version 3.1. Based on moderate effect sizes reported in the literature (Lengkana et al., 2019), the effect size was set at f = 0.30, with a significance level of α = 0.05 and statistical power of 1 - β = 0.95. Power analysis for a repeated-measures design with three groups and two measurement time points (baseline and post-intervention) indicated a minimum total sample size of 48 participants. To account for potential dropouts, a total of 54 participants will be recruited. Participants will be assigned to the study groups using block randomization stratified by age and sex. Primary Outcome Measure: Balance and postural control will be assessed using the Biodex Balance System. Secondary Outcome Measures: Body composition will be evaluated using Body Mass Index (BMI), triceps and subscapular skinfold thickness, waist circumference, and Bioelectrical Impedance Analysis (BIA) to determine body fat percentage. Core muscle endurance will be assessed using the Prone Plank Test and the Side Plank Test. Functional performance will be evaluated using the 6-Minute Walk Test (6MWT), the 30-Second Sit-to-Stand Test (30-s STS), and the 20-Meter Shuttle Run Test. Physical activity level will be assessed using the Physical Activity Questionnaire for Children (PAQ-C). Self-perception and body image will be evaluated using the Self-Perception Profile for Children (SPPC). Health-related quality of life will be assessed using the Pediatric Quality of Life Inventory (PedsQL), while fatigue will be evaluated using the PedsQL Multidimensional Fatigue Scale. Posture will be assessed using the New York Posture Rating Scale. Study Plan: Each exercise session will last approximately 40 minutes, consisting of…
