The findings from this project may result in pain reduction and improved mobility in pregnant women with pelvic girdle pain in their second and third trimester.


The primary objective of this unblinded randomized controlled trial is to determine whether superficial cryotherapy results in improved Numeric Pain Rating Scale (NPRS) scores among pregnant women with posterior pelvic girdle pain. The investigators hypothesize that superficial cryotherapy, in addition to receipt of an educational pamphlet, will result in improved NPRS scores compared to receipt of an educational pamphlet alone.

This study will include English-speaking pregnant women presenting to Loyola University Medical Center obstetrics or rehabilitation clinics in their second or third trimester with posterior pelvic girdle pain, defined as an NPRS score > 2 onset within the past 3 months and pain experienced between the posterior iliac crest and the gluteal fold, particularly in the vicinity of the sacroiliac joints (SIJ). The pain may radiate in the posterior thigh and can also occur in conjunction with/or separately in the [pubic] symphysis. NPRS scores will be measured as a continuous, numerical integer ranging from a value of 0 (No pain) to a value of 10 (Worst possible pain).
