Comparison between tripod and skin-fixed recording of scapular motion

Tracking the scapula using the scapula locator with and without feedback from pressure-sensors: A comparative study

“…The measured scapular internal and upward rotations of the two methods are largely comparable to previous studies but the tilt measured in this study is more anterior than in other studies (Meskers et al, 1998, Meskers et al, 2007. This is likely to be caused by inter-individual differences (de Groot, 1997), and also because of the small subject groups employed by all these studies which means that they are not representative of the same overall population.…”

Measurement of Dynamic Scapular Kinematics Using an Acromion Marker Cluster to Minimize Skin Movement Artifact

“…The acromion method is non-invasive and provides dynamic three-dimensional measurement of scapular kinematics. Validation studies have shown the acromion method to be valid up to 120° during the arm elevation phase when using electromagnetic sensors 17,27 . When using marker based motion capture devices a series of markers arranged in a cluster, the acromion marker cluster (AMC), is required and has been shown to be valid when using an active-marker motion capture system 28 and whilst using a passive-marker motion capture system during arm elevation and arm lowering 29 .…”

Skin-fixed scapula trackers: A comparison of two dynamic methods across a range of calibration positions

“…The equivalent RMS errors found in this study were compared to those of a previous bone pin study (Karduna et al, 2001) and the parallel study with the AM (Shaheen et al, 2010a) at the standard calibration position (Meskers et al, 2007). The effect of calibration angle on the ST and the AM was analysed with respect to the actual error and the mean RMS errors across the range of motion.…”
