Hip Disease, Hip Pain Chronic
Conditions
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).
Interventions
OTHERPatient Self-Administered Diagnostic Exam
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.
OTHERClinician-Performed Diagnostic Exam
A clinician-performed diagnostic exam will be completed on the patients.

Inclusion criteria
* Age: 18-80 years * Seeking care for hip related pain and/or clicking, catching, giving way or stiffness * Able to sign or verbalize study consent * No other medical conditions (e.g. gynecological or urinary pathology) that may affect study results * English speaking
Exclusion criteria
* Patients with primary lumbar spine, sacro-iliac or other non-hip related pain as determined with clinical examination * Previous hip surgery * Previous hip injury that would normally exclude from examination as standard practice * Unable to sign or verbalize consent * Other non-musculoskeletal pathology that may affect study results (e.g. gynecological or urinary pathology) * Non-English speaking
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Sensitivity | End of clinician examination, 20 minutes | 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). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Specificity | End of clinician examination, 20 minutes | 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). |
| Diagnostic accuracy measure of positive likelihood ratio | End of clinician examination, 20 minutes | As measured by sensitivity and specificity values. |
| Diagnostic accuracy measure of negative likelihood ratio | End of clinician examination, 20 minutes | As measured by sensitivity and specificity values. |
| Diagnostic accuracy measure of post-test probabilities | End of clinician examination, 20 minutes | As measured by analysis of the pre-test prevalence of the condition and determination of the post-test shift in probability of the condition. |
