Table 7.
Unstandardized beta coefficients and p values for LME models investigating the changes in articulator measures over time, beyond speaking rate.
| Articulator | Outcome measure | Predictor | Fixed covariates | b | p |
|---|---|---|---|---|---|
| T+J | Movement range (mm) | Time in study (months) | Sex; J range (mm); speaking rate (WPM) | −0.162 | .019* |
| Maximum movement speed (mm/s) | Time in study (months) | Sex; J maximum speed (mm/s); speaking rate (WPM) | −2.61 | .035* | |
| J | Movement range (mm) | Time in study (months) | Sex; speaking rate (WPM) | 0.011 | .821 |
| Maximum movement speed (mm/s) | Time in study (months) | Sex; speaking rate (WPM) | 0.69 | .547 | |
| Movement duration (s) | Time in study (months) | Sex; speaking rate (WPM) | 0.01 | .065 |
Note. LME = linear mixed effects; T+J = tongue and jaw; J = jaw.
