Comments on “Concurrent validity and precision of the thumb disability examination (TDX) in first carpometacarpal osteoarthritis” by Johnson et al.

I read the article with great interest by Johnson et al. entitled “Concurrent validity and precision of the thumb disability examination (TDX) in first carpometacarpal osteoarthritis.”1 The authors of the study were purposed to reveal the concurrent validity, test-retest reliability, standard error of measurement (SEM) and minimal detectable change (MDC) of th e TDX. I congratulate the authors of the study; as they also stated in their article, there is no available tool for assessing osteoarthritis in the thumb carpometacarpal joint.
