Interrater and Intrarater Reliability of the Active Hip Abduction Test

The Interrater Reliability of Physical Examination Tests That May Predict the Outcome or Suggest the Need for Lumbar Stabilization Exercises

“…Nevertheless, the interrater reliability found in our study suggests that this scoring method is acceptable for clinical use. In contrast to the findings of Davis et al, 12 we found poor interrater reliability for the AHAbd test. Two main reasons are likely to be responsible for this.…”

“…First, we used direct observation of subjects performing the test in real time. The study by Davis et al 12 relied on observation of video clips of subjects during the performance of the test. This methodology is more likely to overestimate the reliability of the test, as it does not include the error resulting from the application of the test procedure, nor from the interaction between the examiner and the subject during the test.…”

“…12 However, this was established through observation of video clips of subjects performing the AHAbd, as opposed to direct observation. 12 Furthermore, the reliability of the test among patients with LBP has not been established. Therefore, additional investigation into the reliability of the AHAbd seems warranted.…”

“…The reliability of the AHAbd has been previously established among asymptomatic individuals. 12 The ICC for the interrater reliability ranged from 0.59 to 0.70, representing fair reliability. 12 However, this was established through observation of video clips of subjects performing the AHAbd, as opposed to direct observation.…”
