Research summary
Quantifying the range of axial rotations of the Glenohumeral joint (GHJ) improves understanding of shoulder motion; having applications in overhead sports and in shoulder rehabilitation following rotator cuff repair. The range of motion of the GHJ is thought to be dependent upon the shoulder bone geometry, meaning this could be used to further understand shoulder motion. The study aims to establish this relationship for a non-pathological group.
Thirty healthy subjects aged between 18 and 40 years will be recruited for the study. The subjects will have no history of shoulder pain or surgery. The movement of the dominant shoulder and upper arm will be collected in the human movement lab at the University of Surrey to quantify the axial rotations of the GHJ. The session will last approximately 90 minutes, where subjects will be asked to rotate their arm internally and externally whilst they are seated and with their arm supported in a splint. The position of the upper arm will be varied to quantify axial rotations at elevations of 60°, 90° and 120° in three elevation planes, allowing the motion of the shoulder to be fully described. Magnetic Resonance Images (MRI) of the shoulder and upper arm will be collected from the same subjects at the Royal Surrey County Hospital. The session will last approximately 30-40 minutes. Data obtained from MRI will allow the quantification of parameters related to the shoulder bones’ (humerus and scapular) geometries.
The movement and MRI data will be used to establish if a relationship between shoulder range of motion and bone geometry exists, hence improve understanding of shoulder motion for a non-pathological group.REC name
