Overview
Brief Summary
This study will be conducted to assess Temporomandibular Joint (TMJ) function across different trimesters of pregnancy.
Detailed Description
Pregnancy is a physiological state that can potentially influence the function and biomechanics of the Temporomandibular Joint (TMJ) due to hormonal changes, weight gain, and other associated factors. TMJ disorders are a common problem affecting a significant proportion of the population, with potential impacts on chewing, speaking, and other daily functions, significantly affecting a pregnant woman's quality of life.
Limited research has been conducted to comprehensively evaluate the changes in TMJ function and proprioception (repositioning accuracy) across different trimesters of pregnancy. By identifying and understanding the specific impacts of different trimesters of pregnancy on TMJ function, this study aims to provide insights that can help in the early detection and effective management of TMJ disorders. This, in turn, can improve the overall well-being and comfort of pregnant women, contributing to a more positive pregnancy experience.
Moreover, physiotherapists currently have limited guidelines specifically tailored for managing TMJ dysfunction in pregnant patients. This study aims to fill this gap by providing evidence-based insights into the mechanisms and risk factors associated with TMJ dysfunction during pregnancy. The findings can inform the development of clinical guidelines and therapeutic protocols that address the unique needs of pregnant women, ensuring safer and more effective care.

Outcomes
Primary Outcomes
Mouth Opening (Eyes Open)
Time Frame: 5 months
The woman opens her mouth maximally. The vertical distance between the upper and lower central incisors is measured using a caliper. One-third of the full temporomandibular joint range of motion (ROM) is used as functional ROM. The caliper is adjusted to this range. The woman practices the motion three times, then performs it actively three times with eyes open. Mean absolute joint position error (JPE) is recorded.
Mouth Opening (Eyes Closed)
Time Frame: 5 months
The woman opens her mouth maximally. The vertical distance between the upper and lower central incisors is measured using a caliper. One-third of the full temporomandibular joint range of motion (ROM) is used as functional ROM. The caliper is adjusted to this range. The woman practices the motion three times, then performs it actively three times with eyes closed. Mean absolute joint position error (JPE) is recorded.
Right Lateral Movement (Eyes Open):
Time Frame: 5 months
From rest, the woman moves her jaw to the right. The horizontal distance between upper and lower incisors is measured. Functional range of motion ROM is calculated (one-third of full ROM). She practices then actively performs the movement three times. Joint position error (JPE) is recorded.
Right Lateral Movement (Eyes Closed)
Time Frame: 5 months
From rest, the woman moves her jaw to the right. The horizontal distance between upper and lower incisors is measured. Functional range of motion (ROM) is calculated (one-third of full ROM). She practices then actively performs the movement three times but with eyes closed. Joint position error (JPE) is recorded.
Left Lateral Movement (Eyes Open)
Time Frame: 5 months
From rest, the woman moves her jaw to the left. The horizontal distance between upper and lower incisors is measured. Functional range of motion (ROM) is calculated (one-third of full ROM). She practices then actively performs the movement three times.Joint position error (JPE) is recorded.
Left Lateral Movement (Eyes Closed)
Time Frame: 5 months
rom rest, the woman moves her jaw to the left. The horizontal distance between upper and lower incisors is measured. Functional range of motion (ROM) is calculated (one-third of full ROM). She practices then actively performs the movement three times but with eye closed. Error of JPE is recorded.
Jaw protrusion (Eyes Open)
Time Frame: 5 months
From rest, the woman moves her jaw forward. Distance between upper and lower incisors is measured. Functional range of motion (ROM) is calculated. Movement is practiced and repeated three times. Joint position error (JPE) is recorded.
Jaw protrusion (Eyes Closed)
Time Frame: 5 months
From rest, the woman moves her jaw forward. Distance between upper and lower incisors is measured. Functional range of motion (ROM) is calculated. Movement is practiced and repeated three times but with closed eyes. Joint position error (JPE) is recorded.
Secondary Outcomes
- Assessment of severity of temporomandibular joint dysfunction(5 months)
- Assessment of temporomandibular joint pain(5 months)
