ActiGraph data for physical activity, gait and balance analysis
In some clinical studies it is important to assess the participant physical activity. Nowadays, this is can be done by asking the participant to wear actigraphy devices which collect 3D acceleration data. Among existing actigraphy devices, devices from ActiGraph (GT3x or GT9x) are the most widely used in the literature. To evaluate the quality of the ActiGraph devices, our project consists of accessing existing public ActiGraph (GT3x or GT9x) dataset for the purpose of studying the device reliability, and quality for measuring physical activity in general (e.g. gait parameters).
Analysis of ActiGraph GT3x or GT9x signal quality like noise level, sample drop
Analysis of ActiGraph ability to measure physical activity like step counts and gait speed.
