Not yet recruiting

• Conditions: Forward Head Posture; Temporomandibular Disorder

• Registration Number: NCT06123351
• Lead Sponsor: Shima Abdollah Mohammad Zadeh

Brief Summary

The goal of this clinical trial is to test the effect of nerd neck correction on damaged jaw in people who suffers from jaw problems and nerd neck. The main question it aims to answer:

* whether there are different effects of traditional nerd neck correction exercises, device correction method and dental splints on jaw features of pain and function.

Participants will:

* participants will be given the consent to sign first.

* participants will be assessed to check jaw pain and function.

* participants will be divided randomly into 3 groups.

* Each group will be given the treatment sessions for 6 weeks.

* participants will come back after 6 weeks for one last assessment.

Researchers will compare traditional, new and dental treatment groups to see if there is improvement in jaw characteristics.

Detailed Description

The relationship between the two conditions of forward head posture (FHP) and temporomandibular joint dysfunction (TMD) have been previously stated with comparing the craniocervical angle (CVA) of TMD patients to the healthy individuals, still a clear relationship couldn't be drawn due to different study limitations such as the lack of subdivision in the TMD patients based on their diagnostic subcategories in addition to, patients posture might have been altered while the photo was captured. Ever since, multiple researchers deliberately investigated the two conditions association and inferred the following: 1. FHP can be a risk factor resulting in TMD where any alteration in the head position produces more tension on the masticatory muscles by changing the mandible position 2. TMD origins from muscular component is more significant than articular component yet the correlation between head posture and TMD is still not clear enough, however, if FHP and myogenic TMD were linked preventive measures can be taken. recently, multiple studies established a relation between the occurrence of FHP in TMD patients which supported the hypothesized relation between them.

Till present, no study has investigated the FHP Denneroll cervical traction orthodontic (DCTO) correction impact alone on TMD and this is where the purpose of this study arises from.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: PARALLEL

Primary Outcome Measures

Name	Time	Method
Anamnestic questionnaire by Fonseca	Baseline (pre-treatment) and week 7 (post-treatment)	To evaluate TMD by 10 questions with their corresponding scores from 0 to 1
Craniocervical angle - CVA	Baseline (pre-treatment) and week 7 (post-treatment)	photographic method to evaluate the angle where an angle less than 50 degrees will be considered as forward head posture

Secondary Outcome Measures

Name	Time	Method
Boley Gauge	Baseline (pre-treatment) and week 7 (post-treatment)	Electronic Digital Caliper to assess mouth opening (active/passive)
Numerical Rating Scale (NRS)	Baseline (pre-treatment) and week 7 (post-treatment)	0-10 scale (zero represents no pain and 10 is the worst pain ever) to record orofacial pain
Mandibular Opening	Baseline (pre-treatment) and week 7 (post-treatment)	Tape to measure the distance between the incisal edges of upper and lower teeth
