inertial measurement unit; accelerometer; gyroscope
It is essential to assess functional arm use or goal-directed movement of the upper limb in neurorehabilitation. Wearable sensors help in the continuous, uninterrupted, and objective measurement of arm movements in natural settings. This dataset contains wearable inertial measurement unit data from 15 participants (10 healthy and 5 hemiparetic individuals) while they perform 15 different activities of daily living wearing two wrist bands. Tasks included fine finger manipulation tasks like writing, using a mobile phone’s touchscreen, walking for patients in wheelchairs, etc.

This dataset contains inertial measurements data (accelerometer, gyroscope and magnetometer), recorded as a part of DoorINet research. Our dataset was recorded using two types of IMUs: Memsense MS-IMU3025 [32] and Movella Xsens DOT [33]. The Memsense MS-IMU3025 was used to generate the ground-truth (GT) readings. This IMU has a gyroscope bias instability of 0.8°/h over the axis of interest Z and was recorded at 250Hz. The Movella Xsens DOT IMUs were used as units under test. It has a gyroscope bias instability of 10°/h over the axis of interest Z and was recorded at 120Hz.
