What happens to disc pressure during decompression?

During decompression, disc pressure decreases in the intervertebral spaces. This reduction in pressure is a fundamental aspect of how decompression therapy works. By creating a negative pressure environment within the disc, decompression allows for the retraction of the herniated or bulging disc material, which can relieve pressure on surrounding nerves and pain in the affected area.

Additionally, as the pressure decreases, it promotes the diffusion of nutrients and healing fluids into the disc, which can aid in the recovery of disc health over time. This mechanism is particularly significant in conditions such as herniated discs or degenerative disc disease, where alleviating pressure can lead to substantial patient relief and recovery.

While other options provide interesting concepts, they do not accurately reflect the physiological changes that occur during decompression therapy. The primary goal and effect of this therapeutic approach is to lower disc pressure.
