Agreement of Clinical Judgments of Endfeel between 2 Sample Populations
Context:The agreement of clinical judgments of endfeel between certified athletic trainers and orthopedic surgeons is not known.Objectives:To examine agreement of clinical judgments of endfeel between sample populations and explore the influence of clinician technique on sensitivity for determining ACL injury when performing an isolated examination procedure.Design:Randomized, blinded, controlled clinical trials.Setting:Laboratory.Subjects:1 orthopedic surgeon, 22 certified athletic trainers, and 12 model patients.Main Outcome Measures:Kappa coefficients were calculated to determine the agreement of clinical judgments of endfeel between the 2 populations sampled. Lachman-test sensitivity was measured using true positive and false negative interpretations.Results:Concurrence was poor for clinical judgments of endfeel. Sensitivity varied according to clinician technique.Conclusion:Agreement between the 2 populations sampled was influenced by the examiners’ diagnostic skills and their capacity to properly perform and interpret the Lachman test.
