Patient Performed Examination for Patients With Intra-articular Hip Pain

Study Overview
=================
Brief Summary
-----------------
The primary objective of this study is evaluate the diagnostic accuracy of a patient self-administered clinical examination of the hip compared with a traditional clinical examination (i.e. index test).

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Patient Self-Administered Exam Group<br>Participants with hip pain presenting in the hip preservation clinics will be asked to complete two diagnostic exams. Participants with hip pain will first complete a patient self-administered diagnostic exam. | Other: Patient Self-Administered Diagnostic Exam<br>* Participants will complete a patient self-administered diagnostic exam. A physician will be available to monitor the patient and record findings but will not physically assist the participants.<br>|
| Active Comparator: Clinician-Performed Exam Group<br>Participants with hip pain presenting in the hip preservation clinics will be asked to complete two diagnostic exams. Participants with hip pain will next complete a clinician-performed diagnostic exam. | Other: Clinician-Performed Diagnostic Exam<br>* A clinician-performed diagnostic exam will be completed on the patients.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sensitivity | As measured by a questionnaire evaluating the diagnostic test's ability to identify a positive finding when the targeted diagnosis is actually present (i.e. true positive). | End of clinician examination, 20 minutes | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Specificity | As measured by the discriminatory ability of the diagnostic test to identify if the disease or condition is absent when in actuality it is truly absent (i.e. true negative). | End of clinician examination, 20 minutes | 
| Diagnostic accuracy measure of positive likelihood ratio | As measured by sensitivity and specificity values. | End of clinician examination, 20 minutes | 
| Diagnostic accuracy measure of negative likelihood ratio | As measured by sensitivity and specificity values. | End of clinician examination, 20 minutes | 
| Diagnostic accuracy measure of post-test probabilities | As measured by analysis of the pre-test prevalence of the condition and determination of the post-test shift in probability of the condition. | End of clinician examination, 20 minutes |
