PID2020-113790RB-I00 data set: relaxation curves during distraction osteogenesis in sheep metatarsus

This data set consist of two types of matlab files that contains the force measurements by sensors installed in the external fixator described in a work which aims to provide a viscoelastic model to the force relaxation during daily distractions in a bone transport process [1]. The data presented here allows to reproduce the relaxations curved fitted in this publication to obtain the viscoelastic model. Type of files: f_dist_XXX.mat Force data for the animal XXX. Data are organized in matrices N*6*M. N force monitoring points (frequency of acquisition 100 Hz), 6 load cells (C1, C2, C3, C4, C5 and C6 in the order of columns) and M different days of distraction. The days of distraction which sere motorized are detailed in other file (time_dist_XXX.mat). To obtain the distraction force (DF) from sensor measurements it is necessary to apply the following expression: DF = C2 + C5 – C3 – C6 time_dist_XXX.mat It is a vector that contains the days in which the distraction phase was monitored for this animal This data set requires WinRAR software to decompress and MATLAB to process .mat data.

Doi: 10.1177/09544119221113692本数据集包含两类MATLAB（Matrix Laboratory）文件，对应文献[1]中针对骨搬运过程（bone transport process）每日牵张期间力松弛（force relaxation）现象构建粘弹性模型（viscoelastic model）的研究——该研究采用安装于外固定架（external fixator）的传感器采集力测量数据。本数据集提供的数据可复现该文献中拟合的松弛曲线，以推导该粘弹性模型。 文件类型分为两类： 1. `f_dist_XXX.mat`：对应受试动物XXX的力数据。数据以N×6×M矩阵（matrix）形式组织，其中N为力监测点数（采集频率为100 Hz），包含6个载荷传感器（load cells）按列顺序依次为C1、C2、C3、C4、C5及C6，M为不同牵张天数。已电动启动的牵张天数详情见另一文件`time_dist_XXX.mat`。若需从传感器测量数据中获取牵张力（distraction force, DF），需使用如下计算公式：DF = C2 + C5 – C3 – C6 2. `time_dist_XXX.mat`：为向量（vector）格式文件，存储该受试动物的牵张阶段监测天数。 本数据集需使用WinRAR软件解压，且需使用MATLAB处理.mat格式数据。 [1] JL Calvo-Gallego、J Mora-Macías、E Reina-Romo、J Domínguez、J Martínez-Reina. 骨搬运过程中骨痂组织松弛特性的演变. 英国机械工程师学会学报H辑：工程医学期刊. 2022, 236(9):1457-146.
