To compare the efficacy of platelet-rich plasma (PRP) injection vs dry needling (DN) for management of trigger points in the masseter muscle in myofascial pain syndrome (MPS) patients.
This randomized controlled trial included 30 clinically confirmed cases of myofascial trigger points (MTrPs) in the masseter muscle who were randomly and equally (1:1) assigned to the test (PRP) and control (DN) groups. Both groups were evaluated for pain (visual analog scale [VAS]), range of functional movements, need for pain medication, patient satisfaction (Likert scale), and sleep (VAS) at baseline and 2-week, 1-month, and 3-month follow-ups. VAS pain and Likert score were also obtained at 6-month intervals.
The use of PRP solution in MTrPs in MPS patients had a better effect on pain and patient satisfaction compared to DN.
PRP appears to be a more effective treatment modality compared to DN in the management of MTrPs in MPS patients.
比较富血小板血浆（PRP）注射与干针（DN）治疗肌筋膜疼痛综合征（MPS）患者咀嚼肌触发点的疗效。
本随机对照试验纳入了 30 例经临床证实的咀嚼肌触发点（MTrPs）患者，将其随机且均等地（1:1）分为试验（PRP）组和对照组（DN）。两组均在基线、2 周、1 个月和 3 个月随访时评估疼痛（视觉模拟评分 [VAS]）、功能运动范围、疼痛药物需求、患者满意度（Likert 量表）和睡眠（VAS），并在 6 个月间隔时获得 VAS 疼痛和 Likert 评分。
在 MPS 患者的 MTrPs 中使用 PRP 溶液在疼痛和患者满意度方面的效果优于 DN。
与 DN 相比，PRP 似乎是治疗 MPS 患者 MTrPs 的更有效治疗方式。
