Gait events

Estimation of gait events from Accelerometer signals

This is a placeholder for an automated service that will provide temporal estimation of gait events from accelerometer signals, positioned at the ankle of healthy subjects. The service would take accelerometer data in a specified format as input and provide the estimated events as output.

Until this service is implemented, please send your data in the specified format to siddhartha.khandelwal@hh.se and nicholas.wickstrom@hh.se.

Specifications

Placement of 3-axis Accelerometer: Anywhere around the ankle

Sampling Frequency: 128 Hz

Input data as 3 vectors: AccX, AccY, AccZ [Accelerometer signals from the X, Y and Z axis, respectively]

Input data format: .mat format

NOTE: The data should consist of ONLY walking and running segments of the signal. Segments corresponding to inactivity or any other activity should be removed from the signals prior to data submission.
