Seventy-four female patients referred to a CMD clinic were randomly selected for an examination of general joint mobility according to Beighton. Thirty of the patients (41%) were classified as hypermobile. Eighty-three percent of the patients with generally lax joints had TMJ involvement in comparison to 41% of the patients with no joint laxity. The difference between these groups was statistically significant (P less than 0.001). Parafunctions and trauma were associated with increased symptoms and signs in individuals with lax joints. In nonlax joint patients, trauma to the head and jaw was significantly correlated to TMJ disorders. The results indicate that general joint hypermobility should be taken into consideration in the diagnosis and treatment of CMD.
74名转诊至颞下颌关节紊乱病诊所的女性患者被随机选取，根据贝ighton标准进行全身关节活动度检查。其中30名患者（41%）被归类为关节活动过度。关节普遍松弛的患者中有83%存在颞下颌关节受累，相比之下，关节无松弛的患者中这一比例为41%。两组之间的差异具有统计学意义（P小于0.001）。副功能和创伤与关节松弛个体的症状和体征增加有关。在关节无松弛的患者中，头部和下颌的创伤与颞下颌关节紊乱显著相关。结果表明，在颞下颌关节紊乱病的诊断和治疗中应考虑全身关节活动过度的情况。
