Abstract
Peripartum posterior pelvic pain is a clinical enigma commonly encountered by physical therapists. It is hypothesized that the release of relaxin hormone during pregnancy may result in ligament laxity, which could lead to sacroiliac instability resulting in pain and decreased function. The purpose of these case reports was to describe the effects of manual physical therapy and therapeutic exercise on a peripartum patient with reports of posterior pelvic pain. Two patients referred to physical therapy by their obstetrician during their pregnancy were recruited for these case reports. During the initial examination, both patients completed a number of self-report measures including the Oswestry Disability Index, a body diagram, and the Numeric Pain Rating Scale. Both patients were treated with muscle energy techniques directed at pelvic and sacral positional faults and therapeutic exercise consisting of transverse abdominis and multifidus neuromuscular re-education; isometric hip abduction and external rotation; and a force closure sacroiliac stabilization program directed at neuromuscular re-education of the anterior and posterior oblique sling systems (hip adductors-contralateral obliques and gluteus maximus-contralateral latissimus dorsi combinations). At the time of discharge, both patients again completed the self-report outcome measures as well as a global rating of change. Both patients demonstrated a clinically meaningful improvement in their pain levels as well as perceived disability. In addition, both rated their global rating of change as "a great deal better." These case reports provide preliminary evidence suggesting that manual physical therapy and therapeutic exercise may be an effective intervention strategy for peripartum patients reporting posterior pelvic pain.
