- University of Malaga
- Brief Summary
Childhood is a critical period for neuromotor development, during which footwear may influence both gait biomechanics and the integration of sensory and motor control processes. This study will aim to analyze brain activity in children aged 6-7 years while walking under three conditions: barefoot, in barefoot-style (minimalist) shoes, and in conventional shoes with heel drop.
A quasi-experimental, repeated-measures study will be conducted, in which each participant will complete a 10-meter walking task under the three conditions, in randomized order. Brain activity will be recorded using a 14-channel wireless electroencephalography (EEG) system (Emotiv EPOC X), and relative spectral power (theta, alpha, beta, gamma) as well as Theta/Alpha and Beta/Alpha ratios will be calculated.
Statistical analysis will include global and regional comparisons (frontal, temporal, parieto-occipital), assessment of hemispheric asymmetry, and multivariate analysis. The study is expected to provide novel information on how footwear type may modulate cortical organization during children's gait, with potential implications for pediatric footwear design and clinical recommendations.
- Detailed Description
Background and Rationale Between the ages of 5 and 8 years, basic movement patterns are consolidated and brain plasticity reaches one of its highest levels. Footwear, as an external factor, may modify both gait mechanics and the quality of sensory input reaching the central nervous system. Previous studies suggest that barefoot walking or minimalist footwear may enhance intrinsic foot muscle activation and proprioception; however, limited evidence exists on how these conditions affect cortical activity in children. Electroencephalography (EEG) offers a non-invasive and real-time method to record brain activity during motor tasks, making it a suitable tool for investigating this phenomenon.
Primary Objective The primary objective will be to analyze cortical activity using EEG in children aged 6-7 years while walking under three conditions: barefoot, in barefoot-style footwear, and in conventional footwear with heel drop.
Study Design A quasi-experimental, repeated-measures, within-subject design will be used. Each participant will be assessed under all three experimental conditions, with the order randomized to minimize learning or fatigue effects.
Participants The study will include 37 healthy children aged 6 to 7 years, with no neurological or musculoskeletal disorders, normal motor development, and no habitual use of barefoot-style footwear in the past six months.
Procedure
Each participant will walk 10 meters in three conditions:
Barefoot
Barefoot-style footwear (3 mm sole, flexible, 0 mm drop, wide toe box)
Conventional footwear with heel drop (rigid sole, 12 mm heel / 7 mm forefoot, 5 mm drop, reinforced heel counter, narrow toe box).
Brain activity will be recorded using the Emotiv EPOC X wireless EEG system (14 channels) and analyzed using EEGLAB (MATLAB). Relative power in theta (4-7 Hz), alpha (8-12 Hz), beta (13-30 Hz), and gamma (30-45 Hz) frequency bands will be calculated, along with Theta/Alpha and Beta/Alpha ratios.
Statistical Analysis A repeated-measures ANOVA and Tukey's post-hoc tests will be applied to compare conditions. Regional analysis, hemispheric asymmetry evaluation, and multivariate analyses (PCA, LDA) will also be performed. Statistical significance will be set at p \< 0.05.
Expected Impact This study is expected to improve understanding of how footwear type influences cortical organization during children's gait. Findings may help inform pediatric footwear design and clinical recommendations to support healthy neuromotor development.
Ethics and Consent The protocol has been approved by the Ethics Committee of the University of Málaga (CEUMA112104). Written informed consent will be obtained from parents or legal guardians, and verbal assent will be obtained from all child participants.

Name Time Method Relative spectral power ratios (Theta/Alpha, Beta/Alpha) during walking in children Day 1 (single data collection session) EEG-based measurement of relative spectral power in theta (4-7 Hz), alpha (8-12 Hz), and beta (13-30 Hz) frequency bands, and calculation of Theta/Alpha and Beta/Alpha ratios across three footwear conditions (barefoot, barefoot-style, conventional with heel drop). EEG will be recorded using a 14-channel Emotiv EPOC X system during a 10-meter walking task. Analyses will compare regional and global cortical activity patterns between conditions.
