title: Interobserver reliability in measuring flexion, internal rotation, and external rotation of the hip using a plurimeter.
abstract: OBJECTIVE
  To determine reliability of the measurement of hip movements (flexion, internal rotation, and external rotation) between medical practitioners.
  
  
  METHODS
  Six clinicians carried out measurements of hip movements on each of six patients with osteoarthritis of one hip, using a specifically designed plurimeter.
  
  
  RESULTS
  There was no evidence of any systematic difference between medical practitioners in the measurement of hip flexion, internal rotation, or external rotation. The degree of agreement was greatest for hip flexion.
  
  
  CONCLUSIONS
  This study has shown that measurement of range of movement at the hip is repeatable between practitioners using a simple plurimeter and may represent an examination that is suitable for monitoring progress and treatment.
