ABSTRACT
The purpose of this study is to compare the effectiveness of the Rolyan, hemisling, remodified Bobath, and the newly designed triangular Bobath slings. Sixteen patients with a shoulder subluxation were evaluated by the simple shoulder AP X-rays with and without slings. The hemisling was applied with the elbow flexed at 90 and 120 degrees. The radiologic evaluation for the detection of shoulder subluxation was done by measuring the vertical and horizontal displacement on a plain AP view. The mean value of vertical displacement without a sling application was 5.21 cm which was reduced to 4.30 cm by a triangular Bobath sling application and 4.32 cm by a hemisling application at 120degrees elbow flexion. These two slings significantly corrected the vertical displacement, but other were not. In nine of sixteen patients, the triangular Bobath sling was the best sling for the vertical correction. All slings except a hemisling increased the horizontal displacement even though it was not statistically significant. The triangular Bobath sling improved the discomfort of the axilla better than the remodified Bobath sling. The results support that the triangular Bobath sling was the best among 4 slings for the correction of shoulder subluxation, although a reduction in lateral displacement and an improvement in applicability need to be explored further.
