Purpose: Previous trials have failed to clearly define interrater reliability for the tape measurement method (TMM) when used by therapists in general. The present trial evaluates whether experience is a significant factor when using the TMM to assess a leg length discrepancy (LLD). It also evaluates the reliability of 2 bony landmarks used as reference points during measurement, the anterior superior iliac spine (ASIS) to medial malleoulus (MM) and ASIS to the lateral malleoulus (LM).
Subjects: 5 healthy physical therapy students conveniently selected from 100 with a range of 25-37 years of age.
Method: 5 experts, with ≥ 10 years experience and 5 novices with < 1 year experience measured the legs of 5 subjects with the TMM, in supine using the ASIS-MM and ASIS-LM landmarks.
Results: Using Model (2,1) of the Intraclass Correlation Coefficient (ICC), for the ASIS-LM, very poor reliability was found with significant variability for novices, ICC=0.172, p=0.03 and poor reliability for experts, ICC=0.348, p>.05. For ASIS-MM, poor reliability was found for novices, ICC=0.209 and fair reliability for experts ICC=0.582 with p>.05 for both groups.
Conclusions: Experience does make a difference. Thus, the TMM is operator dependent and the ASIS-MM yields higher reliability than ASIS-LM.
