Overview

Rocabado's 6x6 exercises are designed to improve muscular co-ordination, relax tense muscles, increase temporomandibular joint (TMJ) ROM, alter the jaw closure pattern and muscle strength. These exercises have been found to be beneficial in reducing pain and increasing masticatory muscle function, as well as restoring restricted joint mobility, muscle length limitation, and postural and functional limitations. In addition, low level laser therapy (LLLT) has been reported to reduce inflammation and pain in patients with TMJ dysfunction. Although that to the best of the authors' knowledge the combined effect of Rocabado's approach with LLLT has not been studied. So, the current study is the first double-blind placebo-controlled clinical trial that investigating the effect of adding LLLT to Rocabado's approach for TMJ myogenic disorders.

Conditions

Myogenic Temporomandibular Joint Disorders

Interventions

The patients will recieve Rocabado's non-thrust manipulation: Non-thrust temporo-mandibular joint manipulations consisted of medial glide, lateral glide and anterior glide as described by Rocabado. Each glide was given for 10-15 repetitions for 5-6 times in a session. The grade of mobilization was beginning with Grade-1 or 2 and progressed to Grade-4 depending on subject condition. Total duration of mobilization was lasted for 20 minutes. in addition to low power gallium aluminum arsenide (GaAlAs).

Outcomes

Primary Outcomes

Assessment of Pain pressure threshold of masticatory muscles

The pain pressure threshold over the temporalis and masseter muscles will be assessed using an algometer with a 1 cm2 probe tip (FDIX Digital Force Gage; Wagner Instruments).

Time frame: change from base line at 6 weeks.

Secondary Outcomes

Assessment of Temporomandibular joint ROM

A therabite will be used to measure mandibular opening

Time frame: change from base line at 6 weeks.

Assessment of the function of Temporomandibular Joints

Temporomandibular Disorder Disability Questionnaire will be used for evaluating the temporomandibular joint function. It consists of the following subsections: the Temporomandibular Disorder Disability Index, Temporomandibular Disorder symptom intensity scale, and Temporomandibular Disorder symptom frequency scale.

Time frame: change from base line at 6 weeks.

Assessment of pain intensity using Numerical Rating Scale

in the rating scale the patient will be asked to indicate a number between 0 and 100 on a horizontal line, that best described his/her perceived level of pain intensity when it is at its worst and when it is at is least.

Time frame: change from base line at 6 weeks.
