Table 2 Intra- and inter-rater reliabilities for assessing masseter muscle stiffness by MyotonPRO.
| Mean±SD | MDC | SEM | Reliability (95% CI) | |
|---|---|---|---|---|
| Rater A in test 1 | 369.5±94.9 | 58.8 | 21.2 | Intra-operator: 0.78 (0.46~0.91)Inter-operator: 0.95 (0.89~0.98) |
| Rater B | 387.4±106.7 | 66.1 | 23.9 | |
| Rater A in test 2 | 350.2±89.5 | 116.3 | 41.9 | |
| CI – confidence interval; SEM – standard error of measurement; MDC – minimal detectable change; SD – standard deviation. | ||||
