Clinical Trial Summary

anterior protrusion of head in relation to the trunk; It has a high prevalence among old women as increased age is associated with a reduced cervical range of motion (ROM), greater thoracic kyphosis which is associated with greater cervical flexion and greater forward head posture accompanying with greater deficits in cervical ROM of flexion and rotation. So, the aim of the study is to determine the effect of forward head posture on temporomandibular joint proprioception in postmenopausal women

Description:

A convenient sample of 100 postmenopausal women will be participated in this study; they are divided into 2 groups according to their cranio-vertebral angle (CVA). The FHP group will be consisted of 50 women, suffer from FHP (CVA was less than 48°). The control group will be consisted of 50 women, are free from FHP (CVA more than 48°). The participants will be recruited from Faculty of Physical Therapy, Cairo University and Faculty of Physical Therapy, MUST University. Informed consent will be obtained from each participant after explaining the nature, purpose, and benefits of the study, informing them of their right to refuse or withdraw at any time, and about the confidentiality of any obtained information.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Measurement of cranio-vertebral angle (CVA)	The CVA is angle formed by a horizontal line drawn through the spinous process of seventh cervical vertebra c7 and line connecting spinous process of c7 and tragus of the ear. the markers will be placed on c7 and tragus of the ear and a photo will be captured by using digital camera from lateral view for three times .Then, the photographs of the woman are then transferred to the device to be analyzed by the Surgimap spine programme which by measuring the angle between a horizontal line passing through C7 and a line extending from the tragus of the ear to C7, calculated the positions of the anatomical points on the photographs to calculate the CVA ,the average of 3 times measurement will be taken, the cut-off point for CVA was 48 °; the woman with less than 48 ° CVA is considered having FHP, whereas the woman with more than 48 ° CVA is considered healthy .	up to 3 months
Primary	Measurement of mouth opening angle	The woman will be instructed to open her mouth as much as possible. The calliper then calculated the vertical distance between the incisal edge of the maxillary central incisor and the labioincisal edge of the opposing mandibular incisor.	up to 3 months
Primary	Measurement of mandibular protrusion	The initial position was the physiological resting position (average space of 3 mm between the occlusal surfaces of the maxillary and mandibular teeth) of the mandible . The woman was told from that role to shift her mandible anteriorly without contact with the tooth. The calliper then measured the gap from the incisal edge of the maxillary central incisor to the incisal edge of the mandibular central incisor.	up to 3 months
Primary	Measurement of lateral movements of the mandible	The initial position was the physiological resting position from which the woman was advised to shift her mandible to the right and then to the left as far as possible. Then the calliper assessed the distance between the labioincisal embrasures of the maxillary central incisor to the labioincisal embrasure of the opposing mandibular incisor.Then, to measure the functional ROM of TMJ, the full ROM of TMJ in each direction was divided by three. In each direction, the caliper was adjusted at the functional ROM to train the woman to move her jaw from the starting position to that functional ROM for 3 times. Then for 3 times with open eyes and 3 times with closed eyes, the woman was asked to shift her jaw actively from the star-ting position to the functional ROM of each direction and the therapist assessed the ROM by the digital caliper in each time.	up to 3 months
