Abstract

Upper limb assistive technology can play an important role in increasing the quality of life for people with neuromuscular disorders by improving their ability to perform activities of daily living and participate in social activities. Questionnaire and laboratory-based studies indicate that in general patients benefit from upper limb assistive technology. However, there is a lack of studies that provide rigorous quantitative and objective measurements during daily life to evaluate the effectiveness and usability of assistive technology. To overcome this issue, we have developed the ArmTracker system, a wearable system based on inertial measurement units (IMUs) that can measure arm movements during daily life. The orientation data from the IMUs is combined with a kinematic model of the upper body to calculate the elbow and wrist positions. We have also developed algorithms to compute metrics that assess the quality of movement, including range of motion, functional workspace, and acceleration-based activity of the upper limb. After validating the performance of the system with a commercially available IMU-based movement capture system (Xsens MVN), we carried out a case study to compare the data extracted from a healthy subject and a subject with Becker muscular dystrophy. The work presented shows the development, validation and preliminary evaluation of the ArmTracker system.
