A public dataset of overground walking kinetics in healthy individuals
收藏资源简介：
The dataset comprises raw kinetic data (both in .mat and .txt) of 128 healthy subjects (52 female, 76 male; M age: 23.8 years, SD 9.1; M body height: 1.76 m, SD 0.08; M body mass: 71.3 kg, SD 13.0; M body mass index: 22.9 kg/m², SD 2.8; M gait speed: 1.33 m/s, SD 0.13) during overground walking. All subjects met the inclusion criteria, which meant that during the study, they were free of lower extremity pain or injuries. In addition, before and during the study, they were free of any gait pathology. The .mat-file 'gait_grf_subject.mat' includes six 128x1 double variables containing one row value for each of the 128 subjects: subject_id [number] subject_gender [1 = "female" ; 0 ="male"] subject_age [years] subject_bodymass [kg] subject_bodysize [m] subject_shoesize [EU] The .mat-file 'gait_grf_rawdata.mat' includes two 1278x1 double variables containing one row value for each of the 1278 gait recordings: data_subject_id [number] data_gait_speed [m/s] and two 1278x1 cell variables containing 8x3000 double variables for each of the 1278 gait recordings: data_analog_fp1/pf2 containing 8x3000 double variables including the raw data in rows: 1. row: fx 1+2 [N] 2. row: fx 3+4 [N] 3. row: fy 1+4 [N] 4. row: fy 2+3 [N] 5. row: fz 1 [N] 6. row: fz 2 [N] 7. row: fz 3 [N] 8. row: fz 4 [N] When using (any part) of this dataset, please cite this dataset and the original article: Horst, F., Mildner, M., & Schöllhorn, W.

本数据集包含128名健康受试者地面行走时的动力学原始数据，文件格式为.mat与.txt。受试者基线信息如下：女性52名，男性76名；平均年龄23.8岁（标准差9.1），平均身高1.76m（标准差0.08），平均体重71.3kg（标准差13.0），平均身体质量指数22.9kg/m²（标准差2.8），平均步速1.33m/s（标准差0.13）。 所有受试者均符合本研究纳入标准：研究期间无下肢疼痛或损伤，且研究前后均无步态病理异常。 名为`gait_grf_subject.mat`的文件包含6个128×1双精度变量，每个变量对应128名受试者的一行数据：subject_id（受试者编号，数值型）、subject_gender（受试者性别，1表示"女性"、0表示"男性"）、subject_age（受试者年龄，单位：年）、subject_bodymass（受试者体重，单位：kg）、subject_bodysize（受试者身高，单位：m）、subject_shoesize（欧盟标准鞋码）。 名为`gait_grf_rawdata.mat`的文件包含2个1278×1双精度变量，每个变量对应1278次步态记录的一行数据：data_subject_id（对应受试者编号）、data_gait_speed（步速，单位：m/s）；同时包含2个1278×1元胞数组变量，每个元胞对应1278次步态记录中的一组8×3000双精度数据：data_analog_fp1与data_analog_pf2，其中8行原始数据依次为：第1行：fx 1+2 [N]、第2行：fx 3+4 [N]、第3行：fy 1+4 [N]、第4行：fy 2+3 [N]、第5行：fz 1 [N]、第6行：fz 2 [N]、第7行：fz 3 [N]、第8行：fz 4 [N]。 使用本数据集（或其任意部分）时，请引用本数据集及以下两篇原始文献： 1.
