A marker set for measuring the kinematics of the lumbar spine and thoracic spine during running: a technical note

“…Similar to the lumbar spine, some investigators have used a marker wand, attached to the posterior aspect of the thorax . In contrast, a number of other studies have been performed using a set of skin-mounted markers placed at a range of different locations on the thorax (Seay et al, 2008;Mason et al, 2014). In a recent study (Mason et al, 2014) we demonstrated good reliability using a rigid plate attached directly to the sternum, as suggested by wu et al (2005).…”

In a recent study (Mason et al, 2014) we demonstrated good reliability using a rigid plate attached directly to the sternum, as suggested by wu et al (2005). However, this configuration can also be difficult to track continuously with passive motion capture system, especially at higher speeds when increased arm movements can obscure sternum markers.…”

“…In this technical note, we report only on lumbar and thorax rotations, however, kinematic data was collected from the feet, lower limbs, pelvis, lumbar spine and thoracic spine. This data was used to derive segmental kinematics using a global optimisation technique (Mason et al, 2014). The precise details of the model and kinematic calculations are provided in detail in another publication (Mason et al, 2014) and here we only provide details of the measurement of the pelvis, lumbar and thoracic segments.…”

“…ISB recommendations (Wu et al, 2005) were used to define the thoracic frame using markers positioned at C7, T6, the suprasternal notch (IJ) and the xiphoid process (XP). Further details of this model are provided in Mason et al (2014).…”

“…Subject completed between 7-10 acceptable trials and for each trial, kinematic data from all possible tracking marker configurations was collected. A global optimisation algorithm (Mason et al, 2014), implemented using Visual 3D (c-motion), was then used to calculate the pose of the lumbar and thoracic segment with respect to the global (laboratory) coordinate system. These calculations were carried out separately for each of the two lumbar and each of the two thoracic tracking marker configurations.…”
