Effect of Change of Direction (COD) Movement on Plantar Pressure and Foot Balance in Bilateral Limbs: Dataset

Description:This dataset contains raw and processed plantar pressure and foot balance data collected during 45° change-of-direction (COD) tasks. Data were obtained from 15 healthy young adults (9 males, 6 females; mean age 22.5 years) using a Footscan® 2-m pressure plate (RSscan International, Olen, Belgium; 480 Hz). Both dominant and non-dominant limbs were tested at a controlled approach speed of 3.5 m·s⁻¹ (±5%).The dataset includes:Raw plantar pressure recordings (ten anatomical regions).Processed 101-point time-normalized stance data.Foot Balance Index (FBI) and foot axis angle metrics.Supporting scripts and analysis outputs for discrete statistics and SPM1d comparisons.These data support the findings reported in the manuscript: “Effect of Change of Direction (COD) Movement on Plantar Pressure and Foot Balance in Bilateral Limbs.”Authors: Haidan Wu, Yi Zhan, Yuming Wang, Justin Fernandez, Qichang Mei (corresponding author)Affiliations: 1.
