I remember in one of our duty hours at the ward, with me being so clueless and empty-headed when it comes to medical equipment before, and being so curious on the stuff connected or being installed to the patients, I never hesitate to ask any who I thought could possibly answer me straight and true.
Thence, I asked my classmate. But it was just on that instance I knew that even she, herself didn’t know what the machine-like stuff rolled at the lower body part of the patient. Just in time, the resident hear us talking about that thing and immediately informed us that it was the patient’s sacroiliac belt or SI belt. But the resident didn’t explained to us more what that sacroiliac or SI belt for.
The Sacroiliac Belt or SI Belt is used to support the sacroiliac joints from any aggravating factors for its pain.
