Brief Summary

The aim of our study is to investigate the relationship between cervical proprioception and cervical muscle endurance with hand-eye coordination and postural control in individuals with forward head posture (FHP) and to compare them with a control group with normal head posture. After the demographic information and physical characteristics of the individuals are recorded, their craniovertebral angles (CVA) will be measured and they will be assigned to Group 1 (forward head posture) or Group 2 (normal head posture). Then, the individuals' cervical proprioception, hand-eye coordination, postural control and cervical muscle endurance values will be measured respectively. Cervical muscle endurance will be evaluated last, taking into account possible muscle fatigue, in order not to affect other measurement results. The recorded values will be compared between groups and the relationship of cervical proprioception and muscle endurance with hand-eye coordination and postural control will be examined. All evaluations will be made by the same researcher.

Detailed Description

Forward head posture is a malalignment defined as anterior translation of the head. This malalignment causes changes in cervical proprioception, decrease in the strength and endurance of the cervical muscles. A decrease in muscle endurance may cause a decrease in cervical proprioception. The cervical region is very important in terms of proprioceptive sensory input and has reflex connections to the (Central Nervous System) CNS. Therefore, abnormal proprioceptive sensory inputs received from cervical mechanoreceptors affect the CNS, which regulates postural control. It has been stated that FHP is associated with a decrease in static and dynamic balance. Head posture has an important role in the sensory information organization of the upper extremity. Hand-eye coordination allows the eyes to coordinate with hand movements.

Identifying the factors that may affect an individual with FHP is very important in planning the rehabilitation program.

The purpose of this study, investigate the relationship between cervical proprioception and cervical muscle endurance with hand-eye coordination and postural control in individuals with FHP and to compare them with a control group with normal head posture.

Arm && Interventions

Group	Intervention	Description
Group 1	Assessment	Individuals with forward head posture
Group 2	Assessment	Individuals with normal head posture

Primary Outcome Measures

Name	Time	Method
Endurance of Cervical Muscles	Baseline	The endurance of the individuals' flexor and extensor muscles will be evaluated by recording the time in seconds that they can maintain the head position initially positioned by the therapist without changing it.
Modified Sensory Organization Test	Baseline	It evaluates the visual, somatosensory and vestibular sensory systems necessary for postural control.; The test will be performed on firm and soft ground, with eyes open and closed conditions. At the end of the assessment, the sway index scores (SI-Sway Index) of all tested conditions will be obtained.
Postural Stability Test	Baseline	This test measures the participants' ability to keep the center of gravity within the limits of the support surface. Depending on the amount of deviation of the center of gravity from the center of the support surface, total stability index (TSI) scores will be recorded. The tests will be performed with eyes open and closed under the conditions of bipedal and unipedal (right side).
Hand-Eye Coordination	Baseline	Individuals' hand-eye coordination will be evaluated by using the Alternate Wall Toss Test and recording the total number of times the ball is thrown and held against the wall without dropping it for 30 seconds.
Cervical Proprioception	Baseline	Proprioception is the joint position sense. Cervical right and left rotation proprioception of individuals will evaluate with a digital inclinometer.
Stability Limit Test	Baseline	In this test, which measures the dynamic balance control of the participants; movement and control skills are evaluated within the limits of the support surface of the center of gravity. Participants' percentage scores of the stability limit in all directions, total percentage score (overall) and time to complete the test (seconds) will be obtained.
