Effect of Forward Head Posture(FHP)on Temopromandibular Joint (TMJ) Proprioception in Post-pubertal Females

Effect of Forward Head Posture(FHP) on Temopromandibular Joint (TMJ) Proprioception in Post-pubertal Females

No studies up to date has been evaluated the effect of FHP on TMJ proprioception.Therefore, this study will be the first one which aims to investigate the effect of FHP on TMJ proprioception in post-pubertal females

Study Overview

• Status: Unknown
• Conditions: Forward Head Posture
• Intervention / Treatment: Other: female with Forward head posture; Other: healthy female without (FHP)

Detailed Description

Forward head posture and temporomandibular disorder are two common problems in post-pubertal females. They are closely related to each other. Previous studies showed influences of head posture on the mandibular rest position, range of functional movements and the jaw and neck muscles work together during rhythmic movements. They affirm that patients with TMD present more alterations in head positioning than patients with no dysfunction .

However, no studies up to date has been evaluated the effect of FHP on TMJ proprioception. The proprioceptors in the human TMJ play important key role in identification of mandibular position when the teeth are not occluded. TMJ receptors provide the greater afferent activity regarding perceptual awareness of joint position and movement . Proper assessment of TMJ proprioception may be critical for designing not only rehabilitation but also pre-habilitation interventions for patients with FHP aiming to prevent TMD. Therefore, this study will be the first one which aims to investigate the effect of FHP on TMJ proprioception in post-pubertal females. This study may expand the role of physiotherapy in woman's health.

Proper assessment of TMJ proprioception may be critical for designing not only rehabilitation but also pre-habilitation interventions for patients with FHP aiming to prevent TMD. Therefore, this study will be the first one which aims to investigate the effect of FHP on TMJ proprioception in post-pubertal females. This study may expand the role of physiotherapy in woman's health.

Number of groups / cohorts

2

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Female with forward head posture; post-pubertal females suffering from (FHP) with Craniovertebral angle (CVA) less than 49 degrees(study group)	Other: female with Forward head posture; measuring tmj proprioception with open eyes and closed eyes for mouth opening,right deviation,left deviation and protrusion,cranio vertebral angle and shoulder angle
healthy female without (FHP); post-pubertal females expected to exhibit an average normal CVA within 10degrees range from 49 to 59 (control group)	Other: healthy female without (FHP); measuring tmj proprioception with open eyes and closed eyes for mouth opening,right deviation,left deviation and protrusion,cranio vertebral angle and shoulder angle

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Testing TMJ proprioception	TMJ proprioception will be tested through a digital vernier caliper for each female in both groups. Each female will be asked to sit on a stool, feet will be rested on the floor, arms will be supported on armrests, knees and elbow joints will assume right angles, and the chair's back will not exceed suprascapular border. With closed eyes, the female's mouth will be opened passively by 3 cm measured by adigital Vernier caliper, which is considered as functional position of jaw for eating and speech. The procedures will be repeated 3 times and maintained for 3 seconds. Then, each female will be asked to open her mouth actively for the target distance and the distance will bemeasured by the caliper.	one month

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
measuring the shoulder angle	The angle formed at the intersection of the line between the midpoint of the humerus and spinous process of C7 and the horizontal line through the midpoint of the humerus. The investigators considered 52° as the reference angle and will be measure like CVA	one month
