Unloading spinal and trunk compressions…
A biomechanical model was used to estimate the load on the spine in the different tasks so as to compare those tasks reliably when done with and without the back support orthose. The results indicate that wearing a brace can significantly unload (remove) forces on the trunk in some situations.
Interestingly and highly relevant was that the disc pressure values (the pressures exerted on discs) with the use of a back support was lower in about two-thirds of the exercises.
In conclusion user reviews are a reliable source of information when deciding on which back support to purchase.
