顎関節症(TMD)における下顎運動学と筋診断との関連を検討する。 顎関節症における筋肉診断の臨床記録370件を分析したレトロスペクティブで記述的な臨床研究。統計解析はSPSSプログラムを用いて行った。 5種類の筋診断を検討した。筋痙攣と中枢性介在性筋痛は発生率が低かったため、統計解析から除外した。分析に含まれた診断は、保護共拘縮、筋膜性疼痛、および筋痛であった。前方および水平面での下顎運動学の低下は筋膜性疼痛と関連していた。開口偏向値を伴う下顎運動学は前頭面で減少したが,水平面での中間値または増加値は保護共拘縮と関連していた.下顎運動学が正常または増加した筋痛は筋痛と診断された。 下顎運動学の値は顎関節症の筋肉診断と相関があり,診断に有用であった.
To study the association between mandibular kinematics and muscular diagnoses in temporomandibular disorders (TMD). Retrospective, descriptive clinical study based on an analysis of 370 clinical records of muscle diagnoses in TMD. Statistical analysis was performed with the SPSS program. Five different muscle diagnoses were considered. Myospasm and centrally mediated myalgia were discarded from the statistical analysis because of their low incidences. The diagnoses included in the analysis were protective co-contraction, myofascial pain, and myalgia. Decreased mandibular kinematics in the frontal and horizontal planes were related to myofascial pain. Mandibular kinematics with deflection in opening values decreased in the frontal plane, but intermediate or increased values in the horizontal plane were related to the protective co-contraction. Muscle pain with normal or increased mandibular kinematics was associated with a diagnosis of myalgia. Values of mandibular kinematics are correlated with the muscular diagnoses in TMD and are useful for diagnosis.
