What is the main function of abdominal compression in an LSO?

The main function of abdominal compression in a lumbar sacral orthosis (LSO) is to enhance stabilization and reduce lordosis. When abdominal compression is applied through the use of an LSO, it helps to stabilize the lumbar spine by supporting the abdominal muscles. This support is crucial for maintaining an optimal spine alignment, which can help alleviate excessive lordosis—a curvature of the lumbar spine that can lead to discomfort and instability.

The increase in intra-abdominal pressure generated by the compression not only aids in stabilizing the spine but also helps to provide better load distribution across the spinal segments, potentially reducing the risk of injury or exacerbation of existing conditions. Consequently, this mechanism can be especially beneficial for individuals who suffer from conditions like low back pain or post-operative recovery, as it promotes healing while providing structural support.

While other functions such as improving lung capacity or assisting in abdominal breathing are important components of overall physical health, they are not the primary roles associated with abdominal compression in this context. Similarly, psychological support, though valuable for emotional well-being, does not directly relate to the mechanical functions of an LSO’s abdominal compression. Thus, the enhancement of stabilization and reduction of lordosis stands out as the core objective of this feature in lumbar sacral orthotics
