The Child Mind Institute has launched the Healthy Brain Network (HBN), an ongoing initiative focused on creating and sharing a biobank of data from 10,000 New York area participants (ages 5-21). To this end, it is critical to accrue large-scale multimodal datasets that capture a broad range of commonly encountered clinical psychopathology. As a result, ambitions to achieve clinically useful tools to assist in the diagnosis and management of mental health and learning disorders are gaining momentum. Technological and methodological innovations are equipping researchers with unprecedented capabilities for detecting and characterizing pathologic processes in the developing human brain. Machine-accessible metadata file describing the reported data: Analysis to date has primarily involved assessment of the symmetry of upper limb activity, however, there is potential to undertake additional analysis such as understanding the differences in the way a prosthesis is used compared to an anatomical arm. Finally, we have included the transposed activity diaries provided by the participants.
We also provide a non-wear algorithm developed for the removal of prosthesis non-wear periods and resulting activity count data corresponding to prothesis wear periods.

The raw unprocessed data files and the activity count data exported from the Actilife software are provided. This dataset offers a potential wealth of knowledge into a poorly understood cohort. Participants included students, working adults, and retirees recruited from across the United Kingdom. This dataset reflects the real-world activities of the participants during their normal day-to-day routines. The upper limb activity of twenty unilateral upper limb myoelectric prosthesis users and twenty anatomically intact adults were recorded over a 7-day period using two wrist worn accelerometers (Actigraph, LLC). However, none of the devices we evaluated was clearly superior or inferior to the rest rather, each device seems to have use cases in which that device excels beyond the others.
We decided that the ActiGraph wGT3X-BT is the most appropriate device for inclusion in the Healthy Brain Network. We then acquired physical instances of 5 of these devices (ActiGraph wGT3X-BT, Empatica Embrace, Empatica E4, GENEActiv Original, and Wavelet Wristband) and wore each of them in our daily lives, annotating our activities and evaluating the reasonableness of the data from each device and the logistical affordances of each device. In order to include an ecological biotracker in the Healthy Brain Network protocol, we first evaluated the specifications of a variety of actimeters available for purchase. For many of these devices, accelerometry provides the basis of measuring both physical activity and sleep with comparable derivative measures. Currently a wide range of personal activity trackers are commercially available, providing a wide variety of sensor configurations. The Healthy Brain Network is an openly shared pediatric psychiatric biobank with a target of 10,000 participants between the ages of 5 and 21, inclusively In adding ecological actimetry to the Healthy Brain Network, we intend to use appropriate, accurate, reliable tools.
