Tight hip flexor musculature causes excessive anterior tilt of the pelvis… hyperlordosis of the lumbar spine… hyperkyphosis of the thoracic spine… hypolordosis of the lower neck with hyperextension of the head at the atlanto-occipital joint… forward head carriage… tight posterior neck muscles… headache.
Once one joint/structure/tissue is injured, compensation patterns usually occur in which the individual offloads physical stress to other areas of the body. This would logically lead to an increased risk of use/overuse/misuse/abuse to these other areas, likely eventually leading to injury.
Assessment/diagnosis of spinal joint dysfunction, whether it is a hypomobility or a hypermobility, is done via motion palpation.
The primary causes of spinal joint hypomobility can be divided into three types: taut soft tissue, bony obstruction, and jammed meniscoid body.
