Abstract
The aimof this study was to assess proprioception in multi-directional instability of the shoulder before and after a new surgical treatment.
A cross-sectional pilot study assessing shoulder proprioception in asymptomatic controls (n=6), pre-operative patients (n=7) awaiting surgery for atraumatic, multidirectional instability having failed a comprehensive rehabilitation programme and post-operative patients (n=7) having undergone thermo-capsular shrinkage of the shoulder and post-operative rehabilitation. Data were obtained using the Proprioception Assessment System developed at this centre following a standardised protocol to record both threshold to detection of passive movement (TTDPM) and reproduction of passive position (RPP) in three positions of rotation. Means and standard deviations are presented.
There were no differences between shoulders in controls and post-operative patients. Despite the small numbers, pre-operative patients showed significant differences (p< 0.05) between shoulders in 2 of the 6 test protocols. Post-operative shoulders had means similar to controls suggesting thermo-capsular shrinkage may help regain shoulder proprioception after injury.
