Table 4. Comparison of the mean masticatory muscle thickness (cm) during mandibular task according to the groups. ALSG: Amyotrophic lateral sclerosis group; CG: control group; SD: standard deviation; RM: right masseter; LM: left masseter; RT: right temporal; LT: left temporal. Statistical significance was calculated using t test (p≤0.05). Significant p-values are indicated in bold.
