Triaxial accelerometer gait dataset: foot and lower back motion during normal and metronome walking

This dataset contains accelerometric data collected from older individuals walking in a controlled environment. The data were recorded using two triaxial accelerometers, one attached to the participant's lower back and the other attached to the foot. Participants were instructed to walk back and forth along a 205-meter corridor under two different conditions:

Normal walking: Participants walked at their preferred walking speed, reflecting their natural gait and pace.

Metronome walking: Participants synchronized their walking pace to a metronome set to their preferred walking cadence. This condition introduced a rhythmic element to the walking pattern, allowing for the study of gait changes when adhering to an external tempo.

Another condition was also measured to introduce a more variable and dynamic walking pattern that reflects everyday pedestrian movement in a real-world context.

Free outdoor walking: Participants engaged in approximately 5 minutes of free walking in an urban environment, navigating city streets. During this activity, only the lumbar accelerometer was used to record data.

本数据集收录了在受控环境中行走的老年个体的加速度计数据。数据采集采用两个三轴加速度计（triaxial accelerometer），一个安装在受试者腰部，另一个安装在足部。受试者被要求在两种不同工况下沿205米的走廊往返行走：
自然行走工况：受试者以自身偏好的步行速度行走，体现其自然步态与步频。
节拍器同步行走工况：受试者按照设置为自身偏好步频的节拍器调整步行节奏。该工况为行走模式引入了节律性要素，可用于研究遵循外部节拍时的步态变化。

此外还增设了另一项工况，以生成更具变异性与动态性的行走模式，还原真实场景中日常行人的移动特征：
自由户外行走工况：受试者在城市环境中沿城市街道间穿行，开展约5分钟的自由行走。在此活动期间，仅使用腰部加速度计（lumbar accelerometer）采集数据。
