Corrective medical device worn around a patient's back
A back brace is a device designed to limit the motion of the spine in cases of bone fracture or in post-operative spinal fusiona, as well as a preventative measure against some progressive conditions or to correct patient posture.
Common back braces include:
Rigid (hard) braces : These braces are form-fitting plastic molds (historically leather) and rigid (typically metal) supports that significantly restrict motion by between 50 and 65% while rotation is limited by up to 70%.[1]
Soft braces : Elastic braces that limit the forward motion of the spine and assist in setting spinal fusions or supporting the spine during occasions of stress (for example, employment requiring the lifting of heavy loads)
Semi rigid braces : Semi-rigid braces combine elements of flexible and rigid braces within one overall design. This is done by adding rigid supports or additional stiff padding and straps to the body of a flexible brace. Sometimes these added rigid supports are removable, allowing the patient to customize the level of stability to their unique needs.[citation needed]
