Minimum lumbosacral orthosis tension required to prevent parastomal herniation while supporting the spine

Due to the high frequency of parastomal herniation (PSH) in colostomy patients, as well as general disagreement regarding its prevention, the application of lumbosacral orthoses (hernia belts) is explored as a non-invasive PSH prevention method of late. Five hernia belt materials were tested axially to quantify hyperelastic behaviour under varying strain rates. With the collected data, the recommended amount of tension in each belt material was defined for patient use. From a clinical standpoint, this data highlights minimum tensile requirements for hernia belts under standard loading, such as insufflation due to defecation or coughing. Consequently, patient-specific belt adjustments can be made given abdominal perimeter, physical activity level, and belt material to provide individualized support.
