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：任何与颞下颌关节及其周围结构相关的稳定性不稳定性均会导致疼痛加剧。其特征为疼痛、功能减退、下颌运动受限。其对患者生活质量的影响极大，其功能与进食、情感表达及社交健康等方面密切相关。
目标：本研究旨在确定肌紧张对抗肌紧张结合声波导入疗法对颞下颌关节功能紊乱中疼痛和开口的影响。
方法：研究纳入了20-45岁的颞下颌关节功能紊乱患者，分配了一个单一的治疗组（肌紧张对抗肌紧张和声波导入疗法）。采用下颌功能限制量表-8评估下颌功能障碍，采用数字评分量表评估疼痛。结果在基线水平和治疗后3周进行测量。数据被收集、分析并阐释以得出结果。
讨论：本研究旨在比较肌紧张对抗肌紧张和声波导入疗法对颞下颌关节功能紊乱患者疼痛和口腔功能的影响。肌紧张对抗肌紧张是减轻疼痛及其相应咀嚼肌功能的治疗方案。
结果：研究结果显示，肌紧张对抗肌紧张结合声波导入疗法在所有变量中均显示出显著且有效的改善（P<0.05）。
结论：本研究证实肌紧张对抗肌紧张和声波导入疗法是改善颞下颌关节功能紊乱个体症状的治疗方法。
