Abstract: Objective To explore the effect and clinical significance of abbreviations for three clinical trials which include iliac pronation test,pubic tubercle tenderness test,and plantar fascia tenderness test (IPP test) on the diagnosis of sacroiliac joint dysfunction by comparing with traditional diagnostic methods.Methods From June 2018 to March 2019,30 patients with sacroiliac joint dysfunction and 30 normal controls were selected to receive the IPP method and traditional diagnostic method respectively,which including several examinations of sacroiliac joint dysfunction, finally,the diagnosis was confirmed by sacroiliac joint injection. The sensitivity,specificity,receiver operating characteristic (ROC) area and sensitivity of the two diagnostic methods for sacroiliac joint dysfunction were compared. Results There was no significant difference between the experimental group and the control group on sex (10 males,20 females:12 males and 18 females) (χ²=0.287.38,P=0.592),and on age[(43.4±11.6) years vs (42.0±14.1)years] (t=0.400,P=0.691). The sensitivity,specificity and area under ROC curve of the traditional method were 33.3%,96.7% and 0.650 (P=0.046). The sensitivity,specificity and area under ROC curve of the IPP method were 76.7%,96.7% and 0.867 respectively (P<0.001). Also the sensitivity between the two diagnostic methods was significantly different (χ²=11.38,P=0.001).Conclusion The IPP method of sacroiliac joint dysfunction has higher diagnostic sensitivity. For patients suspected of sacroiliac joint dysfunction,comprehensive physical examination should be carried out to make early diagnosis,avoid missed diagnosis and reduce the risk of fail back surgery syndrome.
