| Variable | RMS-SD | ICC | ICC 95% CI | ICC Significance |
|---|---|---|---|---|
| VECDI Rater 1* | 0.629 ΔTU | .842 | .729-.917 | p < .001 |
| VECDI Rater 2* | 0.619 ΔTU | .757 | .457-.925 | p < .001 |
| VECDI Inter-Rater | 1.737 ΔTU | -3.114 | -52.4–0.158 | p = .975 |
| Dorsum PROM* | 1.877 deg | .967 | .939-.983 | p < .001 |
| Posterior PROM* | 1.516 deg | .965 | .937-.983 | p < .001 |
| MFW-WB* | 0.604 mm | .994 | .988-.997 | p < .001 |
| MFW-NWB* | 1.076 mm | .979 | .962-.990 | p < .001 |
VECDI = Vibration energy with color Doppler imaging; ΔTU = change in threshold units, PROM = Passive Range-of-Motion; MFW-WB = Midfoot width–weight bearing; MFW-NWB = Midfoot width–non weight bearing; RMS-SD = root mean square of successive differences; ICC = Intraclass correlation coefficient,
