EXPLORING THE MINIMAL, MODERATE AND MAXIMAL IMPORTANT DIFFERENCES FOR THE 6MWT POST TOTAL KNEE ARTHROPLASTY: WHICH IS THE APPROPRIATE CHANGE METRIC?
Presenter: Naylor JM
This module addresses:
Question: Is the minimal, moderate or maximal important difference (MID,
MoID, MaID) the most appropriate change metric for the 6 minute walk test
(6MWT) post total knee arthroplasty (TKA)?
Conclusion: Thresholds for important improvements were obtained,
however, no threshold classification method was a good predictor of
Key Practice Points:
• A patient-perceived important change threshold may not be a possible
metric for the 6MWT post-TKA
• Identifying important change remains challenging for clinician
• Linking a change in 6MWT to a functional change may be more relevant
