Relation Between Cervicogenic Headache and Forward Head Posture

Overview

This study will be designed to determining whether there is a relationship between CGH and cervical posture which may potentially provide physical therapists with evidence supporting the assessment and treatment of abnormal posture in this patient group.

Headaches have been posed to be a common occurring complaint being as frequent as 66% in general population. One the common types of headaches is Cervicogenic Headache which is considered as a secondary headache whereas the symptoms occur due to cervical spine and its bony components, disc or soft tissue structures. Cervicogenic headache is a syndrome described as pain felt on one side of the head, relating same side neck, shoulder and arm pain that is aggravated by neck movements or sustained head posture The prevalence of CGH has been reported 4.1% in general population 17.5% in patients and 41.4% in medical students. The most general cause of cervicogenic headache (CGH) is the alteration of structure in the neck due to bad posture. Proper posture is defined as a musculoskeletal balance which involves a minimal amount of stress and strain on the body , Forward head posture (FHP) is one of the commonly recognized types of poor head postures in the sagittal plane.FHP was defined as 'any alignment in which the external auditory meatus is positioned anterior to the plumbline through the shoulder joint. Sustaining the head in this forward posture for prolonged period of time has been associated with the development of other musculoskeletal disorders such as 'upper crossed syndrome', which leads to reduction of lordosis in lower cervical and kyphosis of upper thoracic vertebra. In the long run, this may cause shortening of muscular fibers muscles involving the atlanto-occipital articulation, overstretching of muscles around joint and leads to chronic neck pain , There are many factors that could contribute to the development of forward head posture such as age, gender frequency of physical activity, occupation, usage of computer and smartphones and others. It is noted that CGHs can often be related to forward neck and head posture, which is accompanied by a high muscular tone of the supporting extensors to keep the head from gravity. Such unstable state causes overstrain of the cervical muscles, and induces headache and neck pain. FHP is a common postural defect among university students. This high prevalence may be related to the prolonged computer use and faulty posture during lectures. Office workers of being sedentary for prolonged periods are liable to adopt forward head posture and thus generating neck strain, sprain and pain. Moreover, forward head posture is commonly found in people spending long periods on computers, mobile phones and game consoles. Cervical dysfunction from abnormal posture has been proposed to aggravate or cause CGH, but there are conflicting reports as to whether there is an association between posture and CGH. Statement of the problem: There is lack of literature concerning the presence of cervicogenic headache among subjects with forward head posture. This study will answer the following question Does forward head Posture is associated with cervicogenic headache? Purpose of the study: This study will be designed to determining whether there is a relationship between CGH and cervical posture which may potentially provide physical therapists with evidence supporting the assessment and treatment of abnormal posture in this patient group. Significance of the study: Ideal posture describes a state of maintaining balance in the body using minimal musculoskeletal activity without causing pain or discomfort. The tendency to stay seated for long periods of time can cause changes in the alignment of the spine, leading to improper posture, such as a rounded shoulder or forward head posture (FHP) .This change in posture can lead to a spatial change between the spine and the line of gravity, causing an overload on muscles and connective tissues . Neck pain or neck dysfunction is a musculoskeletal disorder caused by improper posture with physical impairment or functional limitation. The FHP is known as an internal factor that causes dysfunction with shoulder and neck pain. FHP results in a posture in which the extended head and upper cervical, and the lower cervical vertebrae flex. This increases the length of the external moment (the arm) by moving the gravitational center (the head) ahead of the load bearing axis. The exposure to this constant load on the craniovertebral extension muscles and the noncontractile structures causes a change in the biomechanical movement, and this increased stress can cause musculoskeletal damage or pain. In addition, FHP can also limit the functional movement in the head and neck area. These limitations are caused by irregular rotation and gliding movement inside the articular capsule whilst moving the joint. Moreover, it was reported that extended periods of FHP can result in a decreased number of sarcomere, as well as shortening of the muscle fibers, which can affect muscular contraction. As mentioned above, there are frequent occurrences of functional movement limitations or non-specific pain in the head and neck region in patients with FHP. Therefore, many studies have described the aspects of FHP that lead to functional movement limitations, and the pain in the head and neck area. It is known that the quality of life in people suffering from headache is worse than in healthy subjects, in addition, this high prevalence disorder has negative health consequences in terms of occupational, economic and social factors. The proposed association between abnormal cervical posture and headache has been demonstrated in migraine and tension-type headaches, but there are conflicting results in CGH. Despite this lack of agreement, clinicians routinely assess and treat altered posture for CGH. therefore, it is important to examine possible associations in order to guide treatment. Hypotheses: There will be no significant relationship between cervicogenic headache and forward head posture.
