Cr/Crn and myostatin correlated moderately with the average annual change of the 6MWT (rho = −0.532 and 0.555, p = 0.02). Dystrophin levels did not correlate with the selected biomarkers nor with performance. Cr/Crn, myostatin, and age could explain up to 75% of the variance of concurrent functional performance of the NSAA, TMRv, and 6MWT.Discussion Both Cr/Crn and myostatin could potentially serve as monitoring biomarkers in BMD, as higher Cr/Crn and lower myostatin were associated with lower motor performance and predictive of concurrent functional performance when combined with age. Future studies are needed to more precisely determine the context of use of these biomarkers.6MWT=6-Minute Walking Test; ADP=adenosine diphosphate; ATP=adenosine triphosphate; BMD=Becker muscular dystrophy; CK=creatine kinase; Cr/Crn=creatine/creatinineratio; CV=coefficient of variation; DMD=Duchenne muscular dystrophy; FVC=forced vital capacity; ICC=intraclass correlation coefficient; NSAA=North Star Ambulatory Assessment; TA=tibialis anterior; TMRv=10-meter run velocity ER -
