The Com-Pressor SI Belt is a uniquely designed sacroiliac belt, allowing pelvic support positioning to be customized to the patient’s needs.
The Com-Pressor™ SI belt is a pelvic compression belt that helps promote pelvic and core stability during retraining of impaired core muscles that may develop from pregnancy, surgery, sprains and more.
Developed by Diane Lee, PT, the patented Com-Pressor allows both the location and level of compression to be easily adjusted around the pelvic girdle using individually applied elastic compression bands. The user places the inelastic belt on first and, then, the support bands can be applied exactly where support is needed. For example, Diane Lee performs a test where she compresses the pelvis in different positions and has the patient lift each leg. Once determining which compression positions yielded the best results, the bands can be placed in those exact spots for personalized relief.
The Com-Pressor pelvic belt is ideal for a number of lumbo-pelvic conditions, from postpartum women to those recovering from injuries such as groin strains, lower abdominal strains, sacroiliac joint instability, hernia, osteitis pubis or impaired core muscle function. It helps restore a functional corset of pelvic compression allowing confident and comfortable core muscle re-training and strengthening.
Non-slip comfort assures user compliance and maximum results, and the low profile design allows patients to wear The Com-Pressor under clothing without unsightly bulkiness. Each Com-Pressor includes one inelastic belt, four elastic compression straps and an instruction booklet; replacement straps are available separately. This product contains latex.

Annemarie Fei –
sizing concerns
medium – large is really medium
extra large is really 5X
there is no true large as the extra large is excessively large and the medium large is too small for the average large person
Otherwise the service is great.

I was not able to sleep on my sides previously due to soreness in the lower back. After wearing belt, I would say 90% of the soreness is reduced. It was very unexpected but utterly amazing.
Robert Phillips Phillips –
Com-pressor belt is wonderful! Sacroiliac pain is quite diminished.
Carolyn Reich –
This belt is amazing. Recommend to my by my Physio it is the perfect adjunct to core strengthening exercises. Relieves my SI joint pain while sitting and standing for long hours. But it is not a substitute for exercises necessary to improve pelvic stability. It is perfectly designed to provide support specifically in areas of concern. As an Occupational Therapist I highly recommend this product.
