Description

Semi-structured data for ankle moment dynamics in human gait is compiled in “AnkleDynamicsExtractedFromRepos.csv.” This data was preprocessed from the following studies: • Lencioni T, Carpinella I, Rabuffetti M, Marzegan A, Ferrarin M. Human kinematic, kinetic and EMG data during different walking and stair ascending and descending tasks. Sci Data. 2019 Dec 6;6(1):309. doi: 10.1038/s41597-019-0323-z. PMID: 31811148; PMCID: PMC6897988. • Fukuchi CA, Fukuchi RK, Duarte M. A public dataset of overground and treadmill walking kinematics and kinetics in healthy individuals. PeerJ. 2018 Apr 24;6:e4640. doi: 10.7717/peerj.4640. PMID: 29707431; PMCID: PMC5922232. After postprocessing the data, ten metadata parameters are indicated per sample: ID: A compressed identification with the following syntax: I-SXX-Mode-Gender-Speed I: Initial from dataset F for Fukuchi et al. and L for Lencioni et al. SXX: Integer to describe specific subjects. Mode: T for treadmill, O for overground. Gender: F for female, M for Male. Speed: five categories of Speed VS, S, C, F, VF. It may contain numbers as the subject might repeat the same trial. Example: F-S03-T-M-VS2 Sample from Fukuchi, subject number 3 walking on treadmill, male, velocity speed is very slow and finally, second trial. Age: Age of the subject Age-Group: four categories are available—“Children,” “YoungAdults,” “Adults,” and “Elderly.” Gender: F or M are the unique categories. Height: float number in cm Mode: Overground and Treadmill. Speed: Five categories mentioned in the description. Following columns are the labels of the postprocessing result: LoopDirection initERP: Initialization point in terms of gait cycle percentage for early response phase. initLRP: Initialization point in terms of gait cycle percentage for late response phase. initDP: Initialization point in terms of gait cycle percentage for descending phase. initS: Initialization point in terms of gait cycle percentage for swing phase. initTS: Initialization point in terms of gait cycle percentage for terminal swing phase. WorkAbs: Absorbed work in J/kg. WorkNet: Net work in J/kg. CP: Linear stiffness in control-plantar flexion. Units (Nm/(kg*rad)) ERP: Linear stiffness in early response phase. Units (Nm/(kg*rad)) LRP: Linear stiffness in large response phase. Units (Nm/(kg*rad)) DP: Linear stiffness in early response phase. Units (Nm/(kg*rad))
