The purpose of this report was to investigate whether a subject with anterior
shoulder instability exhibited better active shoulder position sense and
3-dimensional (3-D) reaching accuracy after a surgical repair. The 19-year-old
male subject underwent an open Bankart repair procedure for his left shoulder
followed by a standardized post-operative rehabilitation program. Shoulder
position sense was examined with traditional passive matching and active
positioning protocols. Reaching accuracy in space with the unrestricted arm
motion was also examined. The subject was tested 5 months prior to the surgery
and re-tested 6 months after the surgery. With the traditional passive matching
protocol, shoulder position sense improved <2 degrees after surgery. However,
shoulder position sense improved greatly after surgery with active shoulder
abduction (up to 4.25 degrees ) and active shoulder rotation (up to 5.87 degrees
) testing protocols. In addition, reaching accuracy also greatly improved after
surgery (up to 10.97 cm) with the most significant improvement when reaching to
targets located in the frontal plane. Data suggest that anterior shoulder repair
with rehabilitation can improve both active shoulder position sense and reaching
accuracy, especially in shoulder positions involving abduction with external rotation.
