It is a breakthrough which could help thousands of women who suffer agony during pregnancy every year.
The solution could be on offer thanks to one mother who knows exactly how terrible pelvic girdle pain can be, reported the Daily Mail.
Ruth Roberts, 41, was confined to a wheelchair and felt like she was being "stabbed repeatedly" while expecting her fourth child.
With the aid of her husband Dafydd, she invented a girdle which supports the weight of the bump while holding the hips in a comfortable position.
It is adjustable and made from breathable, latex-free material which can be worn above or beneath clothing.
