背景:肌筋膜疼痛综合征(MPS)是颞下颌关节病的一种特殊类型。比较各种治疗方法的研究结果很少且有争议。因此,这项研究旨在比较超声治疗的有效性,稳定夹板,TheraBite装置,和咀嚼肌锻炼可降低MPS患者的疼痛强度并改善下颌骨活动度。
方法:这是单盲的,随机化,平行组,2023年4月至2023年10月在固定修复学系进行的主动对照试验,大马士革大学。包括年龄超过18岁的肌筋膜疼痛患者,伴有有限的下颌张开和持续至少6个月的疼痛。使用在线随机软件将80例患者随机分为四组:超声治疗,稳定夹板,TheraBite装置,和咀嚼肌肉锻炼。只有结果评估人员被掩盖了治疗分配。运动方案是TMD患者的运动计划。在基线(t0)考虑了以下主要结局指标,在第一个(t1),秒(t2),和治疗的第四(t3)周,在随访的第二个(t4)和第五个(t5)月:使用视觉模拟量表进行疼痛强度,最大齿间开口,右侧运动,左横向运动以毫米为单位。
结果:在超声治疗中,疼痛程度在t3时从重度变为轻度,稳定夹板,和TheraBite设备组。在咀嚼肌肉锻炼组中,它变成了适度的,超声治疗(p=0.012)和稳定夹板(p=0.013)组之间存在显着差异。此外,在随后的随访期间(t4和t5),下颌活动度持续改善.
结论:在5个月的随访后,所有疗法都同样有效。然而,超声治疗和稳定夹板有实现快速改善的好处。

BACKGROUND: Myofascial pain syndrome (MPS) is a particular type of temporomandibular joint disorder. Research findings comparing various treatment approaches are scarce and controversial. Therefore, this study aimed to compare the effectiveness of ultrasound therapy, stabilization splint, TheraBite device, and masticatory muscle exercises in reducing pain intensity and improving mandibular mobility in patients with MPS.
METHODS: It was a single-blind, randomized, parallel-group, active-controlled trial that took place between April 2023 and October 2023 at the Department of Fixed Prosthodontics, Damascus University. Patients older than 18 years old with myofascial pain accompanied by limited jaw opening and pain lasting for at least 6 months were included. Eighty patients were randomly assigned into four groups using online randomization software: ultrasound therapy, stabilization splint, TheraBite device, and masticatory muscle exercises. Only outcome assessors were masked to treatment allocation. The exercise regimen was the exercise program for patients with TMD. The following primary outcome measures were considered at the baseline (t0), at the first (t1), second (t2), and fourth (t3) week of treatment, and at the second (t4) and fifth (t5) month of follow-up: pain intensity using the visual analogue scale, maximum interincisal opening, right lateral movement, and left lateral movement measured in millimeters.
RESULTS: The pain level changed from severe to mild at t3 in ultrasound therapy, stabilization splint, and TheraBite device groups. In the masticatory muscle exercises group, it changed to moderate, with a significant difference between ultrasound therapy (p = 0.012) and stabilization splint (p = 0.013) groups. In addition, the mandibular mobility continued to improve at the subsequent follow-up periods (t4 and t5).
CONCLUSIONS: All therapies are equally effective after 5-month follow-up. However, ultrasound therapy and stabilization splints have the benefit of achieving rapid improvement.
