3D ROM Histograms
Wearable sensor technology, particularly inertial measurement sensors are used in various motion analysis including applications in sport,
medicine, and rehabilitation of patients after stroke. We are interested in deriving biomarkers to evaluate the patient’s recovery trend, motion performance and level of activity. See also our research projects about biosystems modelling for stroke rehabilitation here and here. In particular, the three-dimensional representation of the range of motion (ROM) provides
clinicians insights into patients motor function. However, 3D representations of motion data derived during free-living activities or functional
therapies remain challenging and not intuitive.
In this research, we analyse the range of motion in patients after stroke. In particular, we develop an intuitive analysis tool based on orientation estimation using inertial sensor data and sensor fusion algorithms.
To gain insights in patients development, e.g. during activities of daily living (ADL), the 3D representation using cubics shows the motion distribution
of the upper arms of both body sides in 3D. We used color-code to illustrate the frequency of targeted cubics.
Work with us
For this research, we offer projects to investigate sensor-fusion algorithms, 3D-motion representation, and reconstruction from sparse sampled sensor-signals
and applications involving motion-animation, trajectory description, and trajectory evaluation.
