FoG-STAR

Parkinson freezing-of-gait, 4 IMUs incl. wrist, severity labels (n=22, Sci Data 2026)

FoG-STAR is a dataset for detecting and characterising freezing of gait in Parkinson's disease from 22 participants wearing four IMUs (accelerometer and gyroscope) on both ankles, the wrist and the lower back. Participants completed seven structured tasks, including walking with and without dual tasks, 360-degree turns and the timed-up-and-go test. Two expert clinical raters annotated 101 freezing episodes and their manifestations, plus activity and task segments.

Original description

We present FoG-STAR, a dataset collected using wearable sensors, designed to support the development and evaluation of algorithms for detecting and characterizing freezing of gait (FoG) in people with Parkinson’s disease (PD). The dataset includes recordings from 22 participants who performed a series of standardized motor tasks while wearing four inertial measurement units (IMUs) on the ankles, wrist, and lower back. Each IMU recorded tri-axial accelerometer and gyroscope data. Participants completed seven structured tasks, including walking with/without cognitive/motor dual-tasks, 360-degree turning, and the timed-up-and-go test, which comprises six types of activities (sitting, standing, sit-to-stand, stand-to-sit, walking, and turning). The dataset features detailed annotations from two expert clinical raters, who marked the onset and offset of 101 FoG episodes, and labelled specific FoG manifestations. In addition, the duration of each activity and task segment was annotated. This multi-level annotation framework allows for studying FoG in the context of dynamic motor behavior and provides a valuable resource for the development of machine learning models aimed at FoG detection, severity assessment, and activity recognition in PD.
