Many clinical spinal complaints are correlated to diurnal (which means the day-night cycle) influences.
It is well known that the intervertebral discs lose and regain hydraulic fluid over the course of this cycle. Specifically, we know water compresses out of the discs and lying down will re-imbibe the loss. Research has shown approximately 16% of change to the lower lumbar discs. Often, patients will have symptoms related to this as some complain of pain in the mornings when the discs are full of fluid and stretch open the annular tears in the discs. This especially occurs under first get-up and when trying to put socks on. A dynamic intervertebral disc model can help the practitioner in the discussion of these pain generators with a dynamic disc to show height loss.
In the Journal of Biomechanics, other research is now looking at other cartilage in the body and specifically, the knee, to see if there are changes from loading and unloading environments. The intervertebral discs in the spine carry the same cartilage as the knee (hyaline cartilage) and therefore this knee research relates to the spine.
Dynamic Disc Designs models are helpful is education of diurnal influences from a clinical level. For example, when the disc squishes down the hyaline cartilage of the facets at the same spinal level can rub and irritate subchondral nerves. This is a common complaint of the spine and our models help the practitioner bridge the research knowledge to the patient in a platform to motivate changes that will improve outcomes.
