Table 4.
Mean of differences of the measured values between pairs of devices together with the 95% confidence intervals (CI) and p-values. Intraclass correlation coefficients (ICC) for mean of different gait variables measured for overlapping phases of system pairs. ICCs reflect absolute agreement (ICC_A) and consistency (ICC_C) of ratings.
