I am best fit into the category of Flat Back on my postural findings for the following reasons:
a. I was found to have a forward head carriage, my thorax thus tends to flatten so to balance against forward tilting CoG of my forward head carriage.
b. I was found to have a flat thorax with apex moving up from normally at T8 to be at T 6.
c. I was found to have a flat lumbar as well with CoG being at L3, and pelvic tilt being decreased to be only 5 while normal pelvic tilt is 10-15. With significantly reduced pelvic tilt my lumbar tends to flatten to balance CoG of my body.
d. All the above factors are interrelated. One could affect the other and vice verse.
The reasons are as follows;
a.In Mid-Thoracic Mobility Screen I failed Wall Angle Test. It was found that my head could not reach wall, the muscles of bilateral sub occipitals were tender and my back head could not touch wall, and thoracic spine could not touch wall. I was also found to be restricted at T5-8 These findings all agree with a flat thorax. In addition I was found to have a short Latissimus Dorsi and Pectoral Muscles which agrees with the findings in postural analysis that my Pectoral Muscles are hypertonic, and that I have a hypotonic abdominals. Lattissimus Dorsi is short to compensate hypotonic abdominals.
b. I also failed Hip Extension Pattern which agrees with postural analysis that I have a weak Gluteus Maximus and my Erector Spinae are short and hypertonic, which also agrees with the a flat lumbar.
c. From P-A postural analysis I was found to have hypertonic Levator Scapulae and hypertonic upper Trapezius and Levator scapulae hypetonic on the left which agrees with the findings in the test of Shoulder Abduction
d.I failed Push-Up Test which is line with that in postural analysis (see diagrams), a short left Levator Scapulae is short and hypertonic to compensate for a weak middle Trapezius/Rhomboid, which also brings left should lower than right.
