| Popis: | Palpation pains of head and neck muscles are important signs of craniomandibulardisorders (CMD). The purpose of this study was to clarify prevalences of palpation pains (PPs) of the muscles in 391 CMD patients. Relationship among PPs examined in different muscles were analyzed with the chi-square test and o-coefficient. The results obtained were as follows.1. Frequencies of PPs ranged from 8.2% for occipital muscle (OC) to 54.7% for medial pterygoid (MP). PPs of the other muscles in this study -superficial masseter (SM), lateral pterygoid (LP), deep masseter (DM), posterior digastric (PD), sternocleidmastoideus (SC), anterior temporalis (AT), posterior temporalis (PT), and trapezius (TR)- were ranked in decreasing order of prevalence.2. Mean rates accompanying the other muscle PPs of the individual muscles were ranged from 43.2% for MP to 81.1% for TR. The other muscles -OC, PT, AT, SC, DM, LP, and SM- were ranked in decreasing order of accompanying rate. That was almost in reverse order of prevalence. The prevalence and accompanying rate of PPs suggest that there was an order in onsets of the muscle disorders of CMD.3. There were strong relationship statistically between PPs of OC-TR, SM-DM, PD-SC, AT -PT, MP-LP, and PD-LP. Those would indicate each, pair of muscles had kinds of functional relations in mastication.These findings could contribute to understanding the muscle functions and the onset mechanisms of CMD. |
