A central tenant of the corrective exercise approach is that strengthening weak muscles and lengthening short muscles will improve posture (Kendal et al 1993). For example Janda (1987) suggested that his lower cross syndrome, anterior pelvic tilt and increased lumbar lordosis, was due to tight erector spinae and hip flexors coupled with weak lower abdominals, gluteals and hamstrings. Hyrsomallis and Goodman (2001) conducted the last significant review on this topic. They concluded that muscular strength was not related to posture based on the research up to that point. However, deeper analysis...
Part 1 discussed why a patient’s sinus tarsi syndrome may have been due to cumulative trauma, driven by over pronation. Then how the patient’s anteriorly rotated pelvis on the same side may have been causing this over pronation. This part will discuss how the upper cervical spine can influence the pelvis and thus the feet.
You will recall from part 1 that this patient had an anteriorly rotated left pelvis. The question then is why? Undoubtedly there was a muscle imbalance holding it in place as shown by his tighter muscles on the front of the left leg and low back. This was coupled...
