One quick Google search and you will learn that posture causes low back pain, neck pain, shoulder pain, headaches, and cardiovascular disease… Amongst many, many other pathologies.

Before we determine the impact of posture on painful conditions, we first need to define what “bad posture” is considered and that starts with the lower and upper crossed syndromes proposed by Dr. Vladimir Janda.

In these models, certain muscles are determined to be “over-active” and “tight”, whereas other muscles are found to be “over-lengthened” and “weak”. These muscular characteristics are then extrapolated to contribute to an individual’s posture, which is then extrapolated to their painful condition.
