Forward Head Posture

I pretty much notice this all the time since school... I'm amazed at how I never saw it before. But, then, 90% makes it "normal".
I know this is an old thread (and perhaps I should not be posting in this forum at all), but I wanted to chime in momentarily with a quick perspective along these exact lines to pass along some modern medicine just coming down the pipes in the past few years. I hope people won't mind hearing what I have to say.
Technically, we all know having a perfect standing alignment is ideal. Yet, as mentioned in above posts, incidence of head forward posture, with a hiked shoulder position, and swayback pelvis or hyperlordosis is extraordinarily common. In addition, the percent of people with this posture, yet no significantly greater than average pathology, is even more remarkable.
In other words, to a degree, head forwards posture is normal and people with it CAN and DO live normal lives, maintaining such postures with tremendous stability from puberty to old age.
To clarify, I do not mean that the spine is meant to operate optimally with the curvatures such a posture leads to. What I do mean is that from modern research, it appears that in otherwise healthy and balanced individuals, such standing postures are more the result of foot structure than muscle balance. That is, for some people, a perfect muscle balance means standing in a head forward, hunched shoulder, swayback/lordosed posture.
The most likely factor leading to such physiology seems to be what is termed forefoot varus. This is a condition where when the ankle/hindfoot is in its straight vertical position, the forefoot is on an incline relative to the ground, such that the big toe is elevated by as much as 3 or 4 cm above the ground.
This picture demonstrates it in a bony sense quite well:

As a result of this foot type (which cannot healthily be corrected with orthotics or even surgical approaches), the feet pronate when bearing weight. As they do so, the legs rotate internally, forcing the pelvis to tilt anteriorly to compensate. Such compensation cascades up the axial and appendicular skeleton. In an individual with forefoot varus, this pronation and its domino effects are what is fundamentally responsible for the posture he/she presents with.
In such cases of forefoot varus, the spine will be capable of relaxing into a proper balance while lying or even sitting following treatment, as described above. However, upon standing, it will immediately or shortly re-curve to accommodate the forefoot deficiency.
Individuals who attempt to counter this natural re-curving and 'force' their spine into compliance with the ideal curvatures (despite their flawed skeletal support) will be met with undue postural strain, leading to issues potentially including: headaches, TMJ, TOS, as well as joint malfunction at the knees, hips, and/or shoulders. As a result, it seems likely that any greater incidence of such dysfunctions among people with varus are more likely the result of their attempts to "stand up straight", following (outdated) postural dogma, than the actual head forward posture they adopt when relaxed.
In a body with varus but otherwise well balanced muscles, pathology should exist at no greater incidence than the general population at young ages. At higher ages, vertebral damage and fusion may occur more readily.
To summarize, convention might have a person believe that all individuals, for optimal health, should stand up perfectly straight. However, we do not come with all the same parts. The new truth is, for optimal health, we should stand in the posture that transmits our weight through our skeletal structure to the ground most efficiently and requires the least muscular input to be maintained. In the case of a patient with significant forefoot varus/pronation, this will be a head forward position.
Caveat: Head forward posture may ALSO be caused by the traditionally expected muscle imbalance involving: excess pec minor, levator scapula, suboccipital, sternocleidomastoid, scalene, and intercostal activity. Patients with such an etiology will be symptomatic in any number of ways, and can be distinguished from healthy varus patients by the tightness of these muscle groups and/or the absence of a significant weight-bearing forefoot pronation. Such patients may or may not remain in a head forward posture after treatment and muscle re-balancing, again depending on their foot type.
The next time a patient comes in with a significantly "abnormal" posture (hiked shoulders, head forward, etc.), if you really want to get into it, tell them to take off their shoes and have a look for pronation at their ankle. If it is present, when not weight bearing, rotate/lift their ankle outwards (supinate) until the ankle is perfectly straight. Observe as the forefoot inclines and the big toe comes upwards. You may be quite surprised to see how significant it can be.
