Motion Capture Camera System for Measurement of Head and Shoulders Position

Volumetric definition of shoulder range of motion and its correlation with clinical signs of shoulder hyperlaxity. A motion capture study

“…The question of simplifying the measurement device is beyond the scope of our study, but innovative techniques are being developed by other research teams. 7 When such simpler devices are successfully completed, SCSV will reasonably be measurable in clinical routine. Finally, it would surely be interesting to have a threshold for hyperlaxity diagnosis in measuring the sum of the passive external rotation/internal rotation at 90 of abduction.…”

“…9 Currently, no shoulder laxity clinical test appears completely reliable 13,17 because of the spectral distribution of shoulder laxity in the population. Furthermore, only a few studies have described SHL from a biomechanical or a motion capture analysis point of view 7,15,16 but confirmed the possible use of a motion capture system (MCS) as an appropriate tool for quantitative assessment of multiaxial shoulder motion.…”

System for Measuring Kinematics of Vestibular System Movements in Neurological Practice

“…The simultaneous measurement of the vestibular system movements could contribute to better understanding of diseases affecting the vestibular system functions [2]. Currently there is a number of proposed methods of measurement and evaluation of the position of the head where the abnormalities in position can be caused by the dysfunction of the vestibular system [3] [4]. Nevertheless, the majority of systems enable us to measure only the movement of the head or of other segments of the body but does not allow us to measure the movement of the vestibular system as such or the movement of the inner ear.…”
