Summary
The Prone Apprehension Relocation Test (PART) shows excellent reliability among healthcare providers for diagnosing hip instability. This supports its use in evaluating painful hips.
Area of Science:
- Orthopedics
- Sports Medicine
- Diagnostic Imaging
Background:
- The Prone Apprehension Relocation Test (PART) is a clinical maneuver used to diagnose hip instability.
- Its clinical utility is dependent on the reproducibility of results among different healthcare providers.
Purpose of the Study:
- To determine the interrater reliability of the PART among physicians, licensed athletic trainers, and physical therapists.
Main Methods:
- A retrospective cohort study (Level 3 evidence) was conducted.
- 96 patients with hip pain were evaluated using the PART by a physician and a physician extender (athletic trainer or physical therapist).
- Interrater reliability was assessed using Cohen κ, with results blinded between examiners.
Main Results:
- Excellent interrater reliability was found for the PART: κ = 0.80 (right hip), κ = 0.82 (left hip), and κ = 0.81 (combined).
- Of 190 hips evaluated, 23 had a positive PART from both examiners.
- A subanalysis showed 19 of 23 positive PART hips had a lateral center-edge angle >25°.
Conclusions:
- The PART demonstrates excellent interrater reliability among healthcare professionals.
- These findings support the use of the PART in the physical evaluation of patients with painful hips.
