A new way to classify movement faults

15th January 2014

Can we identify movement faults even when everyone moves differently - this is a such a current topic. And even more so at the scapula.

This paper looked at a novel multivariant classification tool to see if people with a history of shoulder pain, who failed a clinical movement control test of the shoulder, could be classified on the kinematic variables. Measure of upward rotation of the scapular at the end of the test had the greatest influence.

Abstract
The aim of this study was to assess the potential of employing a classification tool to objectively classify participants with clinically assessed movement faults (MFs) of the scapula. Six participants with a history of shoulder pain with MFs of the scapula and 12 healthy participants with no movement faults (NMFs) performed a flexion movement control test of the scapula, while scapular kinematic data were collected. Principal component scores and discrete kinematic variables were used as input into a classifier. Five out of the six participants with a history of pain were successfully classified as having scapular MFs with an accuracy of 72%. Variables related to the upward rotation of the scapula had the most influence on the classification. The results of the study demonstrate the potential of adopting a multivariate approach in objective classification of participants with altered scapular kinematics in pathological groups.
