Objective To evaluate efficacy of stress fracture (SF) during basic training for military recruits using clinical diagnosis method. Methods Two hundred and eighty eight suspected SF were checked clinically and with bone scanning as golden standard. Results Sensitivity, specificity, accuracy, positive and negative predictive value, positive and negative likelihood ratios and Youden's index of clinical diagnosis were found to be 97.5 %, 61.7 %, 91.7 %, 92.9 %, 82.9 %, 2.55, 0.04 and 0.59 respectively when calculated with cases. The agreement rate between two physicians was 81.7 % with kappa value 0.64. When calculated with position, the precious measures were 97.2 %, 84.1 %, 89.7 %, 82.0 %, 97.6 %, 6.12, 0.03, and 0.81 respectively. The agreement rate between two physicians was 94.4 % with kappa value 0.88. Conclusion Efficacy reliability and agreement of clinical diagnosis for SF seemed to be satisfactory. |
