Camptocormia monitoring with wearable sensor system

Goal: We aim to devise a system which is able to deliver a unique parameter for quantifying the state and progress of camptocormia. This requires long-term assessment (in excess of 24 hours) in a natural environment.

Measurement of camptocormia trunk flexion using a dual-sensor measurement setup

Assessing the flexion of the trunk of patients with camptocormia is a key factor in developing therapies for camptocormia and monitoring their success. Currently used methods to measure this camptocormia angle are based on photographs or short videos. Both methods are not able to take the ability of patients into account to compensate their symptoms for short amounts of time. We propose a simple two sensor measurement setup based on two accelerometers to measure the angle in accordance with the established perpendicular measurement method [1]. We show that our method yields an average deviation of -1.74° with a maximum deviation of +2° and -6° compared to visual assessment with a motion capturing system. Paper on

Live Demonstration: Dual-Sensor Measurement of Camptocormia Trunk Flexion

This demonstration uses custom-made inertia sensors to monitor the flexion of the trunk, which is an important indicator for camptocormia. An underlying mathematical model enables the use of only two sensors attached to the body. The measured angle is indicated in real time on a computer screen and reflected by the positioning of a robotic arm. Paper on
