Table 1

Mean percentage of the separate four echo-types and tendon thickness are denoted for the symptomatic and asymptomatic tendons

  • Echo-types I+II (structure-related) and II+IV (non-structure-related) are grouped. The p values for the difference between symptomatic and asymptomatic tendons and intraclass correlation coefficient (ICC) values for the two observers are also presented for the echo-types and mean tendon thickness. The difference in all measured ultrasonographic tissue characterisation parameters between symptomatic and asymptomatic tendons was statistically significant.
