Outcome data will be analyzed using intention to treat analysis to account for any subjects that drop out during the course of study. Outcome measures of pain using NRS-11 and jaw ROM using the TheraBite ROM Scale will be assessed at baseline, immediately after the 2-week intervention, and at 2 week, 4 week, 6 week, and 8 week follow up periods. Although NRS-11 pain measures are technically classified as ordinal measures, most studies using NRS-11 as an outcome measure utilize parametric tests and consider the measures as interval or ratio data rather than ordinal measures.27 Therefore, assuming homogenous variance and a normal distribution, a parametric 2-tailed mixed-ANCOVA will be used as the primary statistical analysis. Prior to the ANCOVA, 2-tailed unmatched t-tests will be run to determine if there are baseline differences between groups in depression, anxiety, and stress levels, and a 2-tailed Mann-Whitney U Test will be run to determine if there are baseline differences between groups in medication use. If there are significant differences (p < 0.05), these will be used as covariates in the ANCOVA analysis as they could have profound impact on the outcomes of the study. The mixed-ANCOVA will be utilized to analyze the effect of the independent variables, Kinesio taping and sham taping, on the dependent variables of NRS-11 pain scores and jaw ROM, while also accounting for the variable of time. Since subjects are assessed multiple times over a course of 10…
