Recurrent glenohumeral joint instability is a common orthopaedic problem. One
possible cause of this repeated instability is a lack of neuromuscular control and kinesthetic sense of the glenohumeral joint. The purpose of this study was to determine whether there is a deficit in joint proprioception in subjects with
recurrent anterior glenohumeral instability as compared with individuals who
had surgical reconstruction. There had two groups: group A (n=12), non-
operative subjects; group B (n=12), patients who have received modified Bankart
reconstruction. Both groups all were active young soldiers. Kinesthesia and joint position sense were measured with a specially designed proprioception testing apparatus. The results revealed significant difference (P <0.05) between the unstable and uninvolved shoulder for both kinesthesia and joint position sense. No significant difference (P > 0.05) were revealed between reconstructed shoulder and uninvolved shoulder in TTDPM and RPP tests. This study indicates that proprioceptive deficit occur after glenohumeral dislocation and may result in abnormal neuromuscular coordination and subsequent reinjury of the shoulder.
Proper surgical reconstruction for unstable shoulder can restore the sensibility of mechanoreceptors around the joint. |
