Dangers of Forward Head Posture

Neutral posture is observed when a plumb line passes through the center of the ear, shoulder, hip, knee and just in front of the ankle (Illustration - LEFT). Forward Head Posture [FHP] is present when the head at rest is positioned in front of the center of the shoulder. The movement of this much weight (About ten pounds) in front of the plumb line causes a shift in the body's Center of Mass, or balance point.

The good news is that the human body has an exquisite self-balancing system to compensate for shifts of the Center of Mass. The bad news is that these compensatory changes can be quite extreme (Illustration - RIGHT ) and cause severe structural stresses and even changes in organ systems.

There is a predictable pattern of compensation as the body realigns the Center of Mass. This is called the Trinity of Forward Head Posture [FHP].

1. Head moves forward of the shoulders. This changes the body's center of mass and center of gravity, triggering a response in the body's balance system.
2. To counter-balance the mid and upper back drifts backward, the shoulders rotate inward.
3. In response to that movement, the pelvis tilts forward

Several major studies have concluded that FHP is a direct indicator of a person's overall health:

• Spinal pain, headache, mood, blood pressure, pulse, and lung capacity are among the functions most easily influenced by posture; however, many symptoms, including pain, may be moderated or eliminated by improved posture.¹
• Hyperkyphotic (hi-per-kie-fah-tick) posture [excessive curvature of the thoracic spine, commonly referred to as hunchback] predicts increased mortality. Interventions specifically targeted at improving hyperkyphotic posture could result in reduced mortality rates.²

What is Kyphosis?

• Researchers found that even mild forward head carriage is “detrimental” to a person’s “overall health”. They concluded that the farther the head/neck moved in front of the seventh (7^th) cervical vertebrae “all measures of health status showed significantly poorer scores” and that this forward translation increased a person’s pain and decreased their ability to function!³
• Researchers at the University of Leeds in the UK found a direct cellular connection between muscles in the neck and a part of the brainstem - called the nucleus tractus solitarius (NTS) - which plays a essential role in regulating heart rate and blood pressure. This finding quite possibly explains why an injury to the muscles of the neck (i.e. whiplash) can at times change a person’s blood pressure and heart rate. It stands to reason that repetitive use injury to these same muscles (i.e. slouched posture at your desk and/or computer, cell phone, tablet use) may very well adversely alter these vital signs too!

Poor Posture Alters Your Vital Signs

Major Effects of Forward Head Posture

- For every one inch the head sits forward of the shoulders, an additional 15-30 pounds of tension is placed on the muscles in the back of the neck.

The Physics of Forward Head Posture

- It has been estimated that a person with Forward Head Posture uses 30% more body energy to keep the body erect.

- As the body shifts, certain muscle groups get stretched and become weak, and other groups shorten, and become weak. This results in degenerative changes that twist and distort the spine and subsequently shorter stature.

 

<sup>There is nothing good about poor posture and regardless of the activity (work or play) posture affects your overall performance. At least 85% of the back/neck pain related issues that enter my office derive from improper posture. Poor bodily usage directly impacts the biological, psychological, and social aspects of our daily lives leaving us dysfunctional, exhausted, and in pain. Implementing proper body mechanics is simply a mindful adherence to good habits that must be practiced with moment to moment awareness.  

Even though poor posture is not self-correcting it can be reversed. A chiropractor near you utilizing manual therapy, therapeutic exercise, and lifestyle advice can help you overcome upper crossed syndrome [see image above] and return you to a neutral posture in no time</sup>

A Best Evidence Synthesis Regarding the Classification and Treatment of Neck Pain

Endorsed by the United Nations on 30 November 1999 and officially launched on 13 January 2000 at the headquarters of the World Health Organization in Geneva, Switzerland the Bone and Joint Decade (BJD) is an international group of healthcare professionals that address the substantial effect that bone and joint disorders have on society, the healthcare system, and the individual. The goal of the BJD is to “improve the health- related quality of life for people with musculoskeletal disorders throughout the world by raising awareness and promoting positive actions to combat the suffering and costs to society associated with musculoskeletal disorders”.[1] This patient centered organization’s motivation has been the establishment of initiatives capable of delivering best-evidence multi-disciplinary healthcare on a global scale.

This focus was evident with establishment of The Task Force on Neck Pain and Its Associated Disorders in 2000. This fifty (50) member Task Force, with members from nine (9) countries, and representing nineteen (19) clinical and scientific disciplines/specialties was mandated with the task of publishing a report outlining the best current evidence regarding the risk and prognosis of neck pain, its assessment/diagnosis, and the effectiveness and safety of invasive and non-invasive treatment methods for neck pain. During this process they were to also identify problems with the current literature so that future studies could be developed. The goal of this seven year project was to empower the public, especially individuals who suffer from neck pain or at risk of developing it. This collaborative effort that included eight (8) universities in four (4) countries and eleven (11) professional organizations who were nonfinancial sponsors produced a document that has changed approaches and views regarding neck pain as well as its prevention, diagnosis, treatment, and management.[2]

Below is the roster of the 13-member Scientific Secretariat who conducted the screening process of 31,878 research citations on neck pain of which 1,203 articles were found to be relevant. 46% (552) of those were found to be “scientifically admissible” for utilization in this synthesis of best-evidence. Aside from this, various other members of the Task Force also conducted four (4) original research projects during its seven year tenure, two that examined vertebrobasilar stroke, one that compared the outcomes of various forms of neck pain treatment, and another that examined work absenteeism due to neck pain.

As Primary Spine Practitioners, the doctors at Life in Motion Chiropractic and Wellness have found this study to be an invaluable guideline for providing our patients with or triaging them to the most effective treatment available for their neck pain.

More specifically, the fact that not only whiplash and nontraumatic disorders but also headaches, arm pain, and generalized symptoms of cervical origin are included in the review is a major strength of this work. Similarly, it’s very useful having both nonsurgical and surgical treatments in the same publication. Moreover, grading treatments according to the likelihood of helpfulness; reporting on prognostic factors and using “suspected etiology” to evaluate treatments are some other examples of the clinical orientation and practicality of this report.” Federico Balagué MD Department of Rheumatology, Physical Medicine and Rehabilitation, Hôpital Fribourgeois – Freiburger Spital Site de Fribourg – Freiburg, Freiburg, Germany Service de Rhumatologie, Médecine Physique et Rééducation, 1708, Fribourg, Switzerland
