Abstract
This study was conducted to evaluate the effect of moist heat pack therapy (MHP) to experimentally induced masseter
muscle pain and muscular fatigue. Fourteen healthy volunteers (14 men, aged 47.2±2.9 years) without past history or present symptoms of temporomandibular disorders (TMD) were participated in this study. All of the subjects were randomly assigned to experimental group and control group in different days. Subjects were treated by MHP on both sides of masseter muscle in experimental group and those of control group got placebo-MHP for 15 minutes, respectively. The changes of Visual Analogue Scale (VAS), endurance time, and EMG power spectrum were measured on the right masseter muscle both before and after sustained fatiguing contraction in each group. As a result of this study, there were not statistically significant differences in endurance time, median frequency (MF), ΔMF, and slope of MF shift during sustained fatiguing contraction in experimental group. VAS measured after sustained fatiguing contraction was significantly decreased in experimental group. Self-directed physical therapy, such as MHP, may be a good treatment choice for the relief of pain and improvement of functional disability in the elderly patients with TMD who are not capable of using occlusal appliance due to loss of multiple teeth and of taking medication due to polypharmacy.
