In contrast to non-industrial cultures, sitting is by far the most predominant posture in industrialized societies. From commuting to and from work, sitting at work, and sitting at home, spending 14-16 hours a day sitting is fairly typical. The time spent standing each day is usually a very distant third to sitting and lying down.
Decades before the advances in technology of our current information society, with its even greater prevalence of time spent sitting, posture authorities from the 1920's and 1930's concluded that an individual's standing posture is primarily the result of his/her sitting posture:
"The slumped posture is the natural result of the fact that our house chairs, the seats occupied by children in schools and by adults in churches, theaters, trains, street cars and other public places, are rarely constructed in such a way as to support the body in a normal posture when it is relaxed. The universality of this condition among civilized people, in the opinion of the writer, gives to this question of posture, and especially the sitting posture, great importance as a health factor. The standing posture is in general simply the natural result of the sitting posture. If the habitual sitting posture is such as to hold the body in proper form, the same poise will be maintained in the erect position."
Hawley (1937) also commented upon the effect of prolonged poor sitting postures on the individual's standing attitude:
"... the relaxed sitting posture generally involves an abnormal degree of thoracic kyphosis with abducted scapulae and a forward position of the head.
Furthermore the increased kyphosis of the thoracic spine with depression of the ribs and a forward position of the head tend to become habitual, thereby increasing the difficulties of proper standing posture...
Thus the standing posture commonly seen in sedentary individuals shows a forward head, depressed thorax, round back, forward shoulders and a prominent abdomen."
On a positive note, Rathbone (1934) felt that proper chair design could improve standing posture: "While the chair is holding the trunk in extended (elongated) position, the neuromuscular system is being patterned in a desirable posture which can carry over into standing and into movements."
Rathbone's comments correlate with the patterning of the neuromuscular system from YogaBack's sacral and lower thoracic supports. YogaBack is Posture Therapy: the more time spent driving or sitting at work with YogaBack, the greater patterning of the neuromuscular system in YogaBack's elongated posture for transforming one's sitting posture, standing posture, and movements.
