Interrater and 1-Week Test-Retest Reliability Estimates for Each of the 4 Conditions Tested in This Study^a

^aValues presented are point estimate (intraclass correlation coefficient [ICC]) and 95% confidence interval (95% CI). Note that only those participants who reported no change in their condition over the course of 1 week, as indicated by the Global Perceived Rating of Change score, were used for the analysis of test-retest reliability. UFT=upper fibers of the trapezius muscle (local sites), TA=belly of the tibialis anterior muscle (distal sites). MDC₉₀=minimum detectable change at the 90% confidence level.
