Effect of Strain-Counterstrain in Combination With Phonophoresis in Patients with Temporomandibular Joint Dysfunction: A Quasi-Experimental Study.

BACKGROUND: Any instability related to the Temporomandibular joint or surrounding structures of the joint results in increasing pain .It is characterized by pain, reduced function, limitation in jaw mobility. It has great impact on quality of life of patients as its functional is directly related to feeding, emotional expression and social health etc.
AIM: This study was focused on determining the effect of strain-counterstrain in combination with phonophoresis on pain and mouth opening in TMJ Dysfunction.
METHOD: The study was included the age of 20-45 years in TMJ Dysfunction to allocate a single treatment group (strain- counterstrain and phonophoresis). Outcome Jaw Functional Limitation Scale-8 was used to measure the jaw disability, Numeric Rating Scale was used for pain . The outcomes were measured performed at baseline and after 3 weeks of treatment. Data was collected, analyzed and elucidate for results.
DISCUSSION: This study to compares the effects of Strain-counterstrain and phonophoresis of pain and orofacial function of patients with TMD dysfunction. Strain-counterstrain and modality are treatment options for lessen the pain and correspondingly function of massters muscles.
.RESULTS: The finding of the study showed that Strain-Counterstrain with Phonophoresis was found to be resulted and effective significant improvement in all the variables (P=<0.05).
CONCLUSION: This study proved Stain-Counterstrain and Phonophoresis as treatment to improve the symptoms in individual with TMJ dysfunction.

背景：任何与颞下颌关节（Temporomandibular joint, TMJ）及其周围组织结构相关的不稳定状态均会导致疼痛加剧。该病以疼痛、功能减退及下颌活动受限为主要特征，因其功能直接关联进食、情感表达与社会健康等方面，故对患者的生活质量影响显著。
目的：本研究旨在探讨张力-反张力疗法（strain-counterstrain）联合超声透入疗法（phonophoresis）对颞下颌关节紊乱病（Temporomandibular Joint Dysfunction, TMD）患者疼痛及张口度的影响。
方法：本研究纳入20~45岁的颞下颌关节紊乱病患者，将其分配至单一治疗组，接受张力-反张力疗法联合超声透入疗法。采用下颌功能受限量表-8（Jaw Functional Limitation Scale-8, JFLS-8）评估下颌功能障碍程度，采用数字疼痛评分量表（Numeric Rating Scale, NRS）评估疼痛水平。分别于基线状态及治疗3周后完成结局指标测评。对收集的数据进行分析并阐明研究结果。
讨论：本研究对比了张力-反张力疗法与超声透入疗法对颞下颌关节紊乱病患者疼痛及口面功能的影响。张力-反张力疗法及该治疗手段可作为缓解咀嚼肌疼痛、改善相应功能的治疗选择。
结果：研究结果显示，联合应用张力-反张力疗法与超声透入疗法可使所有观察指标均得到显著改善（P<0.05）。
结论：本研究证实，张力-反张力疗法联合超声透入疗法可改善颞下颌关节紊乱病患者的相关临床症状。
