Abstract
Temporomandibular disorders (TMD) consist of a group of symptoms such as: pain of temporomandibular joints, masticatory muscles or surrounding tissues, dysfunctions of TMJs’ mobility, and crepitation. The Hypermobility Joint Syndrome (HJS) manifests in the flaccidity of joint structures, an increase in the range of joint motion, and occurs more often in the young and women. The aim of this study was to present the occurrence of HJS among patients with myogenic TMD and disc displacement with reduction. The secondary goal was to assess the effectiveness of physiotherapy directed to TMD with coexisting HJS. The study involved 322 patients with symptoms of TMD. HJS was diagnosed using the Beighton Scale, which confirmed its occurrence in 26 cases. 79 subjects (7 males and 72 females; mean age, 33.9 ± 10.4 years) were selected and divided into two groups: HJS + TMD (n = 26; 2 males and 24 females; mean age, 27.1 ± 9.4 years) and TMD (n = 53; 5 males and 48 females; mean age, 37.4 ± 9.2 years). These patients completed 3-week physiotherapy management. Before and after physiotherapy, the myofascial pain severity on Numeric Pain Rating Scale, linear measurement of maximum mouth opening, and opening pattern, were assessed. To demonstrate differences between the results, the level of significance for statistical analysis was set at α = 0.05. A statistically significant improvement was obtained in decreasing myofascial pain in both groups. Coordination of mandibular movements was achieved in both groups. Generalized joint hypermobility occurred among patients with TMD. Physiotherapy directed to TMD was effective in reducing myofascial pain and restoring TMJ’s coordination also in patients with HJS.

Hypermobility Joint Syndrome (HJS) is a generalized, congenital connective tissue disorder caused by a defect in the collagen ratio and occurs with a frequency of 2–57% [8]
Generalized joint hypermobility is almost twice as common in women and dominates in the young. It manifests in the flaccidity of joint structures, the joint capsule and ligaments, and an increase in the range of joint motion compared to the physiological norm, iations
Summary
Temporomandibular disorders (TMD) affect temporomandibular joints’ (TMJs) structures, masticatory muscles, and surrounding tissues [1]. Symptoms characteristic of these dysfunctions are impaired TMJ mobility and surrounding tissue pain, limitation of joint function, and crepitations [2]. Symptoms are more common in women than men and increase with age [3]. Generalized joint hypermobility is almost twice as common in women and dominates in the young. It manifests in the flaccidity of joint structures, the joint capsule and ligaments, and an increase in the range of joint motion compared to the physiological norm, iations
