Orthopedic Physical Examination & Clinical Assessment Guide

Ely's Test (Duncan-Ely) Orthopedic Special Test

What is it used for?

  • Assessing spasticity or tightness of the Rectus Femoris.

How to Perform

  • Position: Patient lies prone.
  • Action: Examiner passively flexes the patient's knee rapidly towards the buttock.

Interpretation of Results

  • Positive Test: The hip on the same side spontaneously flexes (buttock rises off the table) because the tight rectus femoris pulls the pelvis anteriorly.

Diagnostic Accuracy

  • Sensitivity: 56-59%
  • Specificity: 64-85%

Clinical Context & Limitations

The Ely's Test (Duncan-Ely) should be considered as one component of a comprehensive musculoskeletal assessment. No single special test has perfect diagnostic accuracy; thus, clinical decision-making should integrate test results with patient-reported symptoms, mechanism of injury, functional impairment, and relevant imaging.

Clinicians should be aware of potential false-positive results in patients with pain sensitisation, muscle guarding, or poor relaxation. For the Hip region, combining the Ely's Test (Duncan-Ely) with complementary examination tests significantly improves overall diagnostic confidence.
