Increase trajectories of tendon micro vibration intensity during ankle plantar flexion: A longitudinal data analysis using latent curve models

This dataset contains statistical features derived from mechanotendography (MTG) signals measured at five levels of exerted muscle strength (0%, 25%, 50%, 75%, and 100% of maximum voluntary contraction) during ankle plantar flexion tasks. The dataset also includes basic participant attributes.<br>Data were collected from 60 healthy adults (30 males and 30 females), aged between 21 and 58 years. The MTG signals were recorded using a piezoelectric film sensor, and the extracted features are expressed in millivolts [mV]. All data are stored in CSV format, with units clearly indicated in the file.<br>To ensure privacy, participant IDs have been randomly reassigned, and all personal identifiers other than age and sex have been removed.<br>This dataset was used in the study titled “Increase trajectories of tendon micro vibration intensity during ankle plantar flexion: A longitudinal data analysis using latent curve models”, available as a preprint at bioRxiv (DOI: https://doi.org/10.1101/2024.10.15.618483).<br>The data are intended to support reproducibility and may be used for follow-up investigations, including re-analysis of MTG signals motivated by questions raised regarding this study.<br>
