Short-term effect of two therapeutic methods on myofascial pain and dysfunction of the masticatory system

In conclusion, a short-term intervention with IS therapy was found to result in a substantial decrease in facial pain for most of the subjects treated. Generally, groups were not found to be significantly different in respect to palpation pain change from session 1 to session 2. Neither therapy significantly altered the range of mouth opening. EMG findings were variable but suggest that RI therapy may alter muscle myoelectric activity. From these findings, ice and stretch of the masticatory and neck musculature would appear to be a good short-term adjunctive therapy to control pain with little apparent risk of negative effects.
