Correcting Sacroiliac Dysfunction: Don't Overlook the Psoas

Dear Editor:

I enjoyed the article by Howard Pettersson, DC, et al., titled "Stabilizing the SI: A Fresh Clinical Approach" [published in two parts in the February 2020 and June 2020 issues].

Correcting SI dysfunction often requires us to look beyond the osseous relationship of the joint itself. However, treating the tight hamstring seems like treating the effect, not the cause. The tight psoas causes flexion deformity, which causes the gluteal weakness, which causes the hamstring tightness.

The muscle that may initiate this cascade is the psoas. When treating the psoas, we should essentially treat the TL spine and femoro-acetabular joints with osseous adjustments, fascial techniques and/or exercises. Integrating the pelvis and TL spine into the treatment of the SI may expand our appreciation and success with an SI lesion.

A Tired, Unsubstantiated Hypothesis

Dear Editor:

I wanted to comment regarding the measles article ["The Measles Vaccine Narrative Is Collapsing" by Dr. Alan Palmer, published in the April 2020 issue]. I am ashamed that the measles article was even included in the Dynamic Chiropractic magazine. Anti-vaccination stances will continue to portray chiropractors as alternative quacks. In light of the current coronavirus pandemic, we should remember how important vaccination is for prevention and treatment of a number of infectious diseases.

I would love to hear the rebuttal of Dr. Palmer's arguments from a reputable epidemiologist. The anti-vax argument is a tired and ultimately unsubstantiated hypothesis that does not stand up to the proven scientific consensus on vaccine safety and efficacy for infectious disease treatment and prevention.
