简要总结
Temporomandibular joint dysfunction (TMD) is a common musculoskeletal disorder affecting the jaw joint and masticatory muscles, leading to pain, limited jaw function, and reduced quality of life. Conservative management includes therapeutic exercises and manual therapy. Rocabado exercises improve jaw mechanics and posture, while the Strain Counterstrain technique reduces muscle tenderness and pain.
This randomized controlled trial aims to evaluate the effectiveness of Rocabado exercises alone versus Rocabado exercises combined with the Strain Counterstrain technique in patients with muscular TMD. The intervention will be conducted over six weeks, with outcomes measured for pain, jaw function, and quality of life. The study seeks to determine whether the combined approach provides superior clinical outcomes.
详细描述
Temporomandibular joint dysfunction (TMD) is a common musculoskeletal condition affecting the jaw joint and muscles of mastication, leading to pain, restricted jaw movement, and reduced quality of life. It is often associated with factors such as muscle spasm, poor posture, stress, and abnormal jaw mechanics. Various conservative treatment approaches are used, including physical therapy, exercises, and manual therapy techniques. Among these, Rocabado exercises aim to restore normal jaw function, improve posture, and enhance neuromuscular control, while the Strain Counterstrain technique focuses on reducing muscle tenderness and pain by positioning the affected muscle in a relaxed state.
This study aims to evaluate the combined effect of Rocabado exercises and the Strain Counterstrain technique on pain, jaw function, and quality of life in patients with muscular TMD. A randomized controlled trial will be conducted on participants divided into two groups: one receiving Rocabado exercises alone and the other receiving a combination of Rocabado exercises and Strain Counterstrain technique. The intervention will be carried out over six weeks, with outcomes measured using standardized tools for pain, functional limitation, and quality of life. The findings of this study may help in identifying a more effective physiotherapy approach for managing TMD and improving patient outcomes.

入选标准
- •Diagnosed patient of muscular TMJ ;According to Fonseca Questionnaire, ranging in the age group of 20 to 50 years, with both male and female were included in the study; Maximum mouth opening (MMO) 40-60mm for diagnosis of muscular TMJ ; Mild to moderate TMJ pain ; Unilateral TMJ ; Diagnostic features of muscular TMJ dysfunction: Pain location: Jaw, temple and masseter region ; Pain Behavior: Increase with chewing, talking and clenching ; Palpation findings: tenderness at masseter and temporal region ; ROM findings: limited and painful mouth opening (<40mm) when measured with maximum mouth opening test ; MMO Test: The test involves measuring the maximum distance between the incisal edges of the upper and lower central incisors when the mouth is opened as wide as possible. This measurement is typically performed using a calibrated ruler, Vernier calipers, or a fiber ruler, with the subject positioned upright and instructed to open their mouth maximally.
排除标准

研究组 & 干预措施
Rocabado Exercises + Strain Counterstrain Technique
Participants will receive Rocabado exercises combined with the Strain Counterstrain technique. A hot pack will be applied for 15 minutes, followed by Rocabado 6×6 exercises and application of Strain Counterstrain to masticatory muscles (masseter, temporalis, pterygoids). Sessions will be 45 minutes, 2-3 times per week for 6 weeks.
干预措施: Rocabado Exercise (Other)

结局指标
主要结局
Jaw Functional Limitation Scale for jaw function (JFLS-8)
时间窗: 6 weeks
Assesses limitations in jaw function in patients with temporomandibular disorders. The JFLS-8 is a short version with 8 items, each rated on a 5-point Likert scale from 0 (no limitation) to 4 (severe limitation). Domains assessed mastication (chewing), jaw mobility (opening/closing), verbal communication (speaking) Scoring as higher scores indicate greater functional limitation. Total score is usually calculated as the sum or average of the 8 items. 0= No jaw functional limitation, 1-3 =Mild functional limitation, 4-6 = Moderate functional limitation, 7-10 = Severe functional limitation. Higher scores indicate greater jaw functional impairment.(20)
Numeric Pain Rating Scale for pain (NPRS)
时间窗: 6 weeks
Measures the intensity of pain. The NPRS is an 11-point scale, ranging from 0 (no pain) to 10 (worst imaginable pain). Patients are asked to rate their current pain, average pain, or worst pain over a specific period (e.g., past 24 hours or week). Interpretation as No pain, 1-3 = Mild pain, 46 weeks-6 = Moderate pain 7-10 = Severe pain
