Research & Statistics Buyer Guides Back and Disc Pressure in Different Positions Chart Sharing is caring! Did you know that pressure on your spine varies greatly among the most common postures we all assume daily? Sitting upright for example exerts up to 40% more pressure on the lumbar spine compared to standing. This is where researchers measure the intradiscal pressure (pressure on the spinal discs) in response to compressive load. You're probably familiar with this chart (below) by Nachemson, where he displays how disc pressure changes (increases and/or decreases) depending on body position.
Back and Disc Pressure in Different Positions Chart Ergonomic Trends
Intravitally-performed measurements of disc pressure over the last 20 years in more than 100 individuals have demonstrated how the load on the lumbar disc varies with the position of the subject's body and during the performance of various tasks, both in standing and in sitting. Disc compression and distraction was verified by disc height in lateral radiographs. The controls (N) showed a level-related range between 0.25 MPa-0.45 MPa. The IVD pressure was highest at level L3/4 (0.42 MPa; range 0.38-0.45) with a decrease in both cranial and caudal adjacent segments. 1.15M subscribers 9.2K views 3 years ago.more.more nabil ebraheim Dr. Ebraheim's educational animated video describes body positions affecting the disc pressure - lumbar spine.Follow me. Under sterile surgical conditions, a pressure transducer with a diameter of 1.5 mm was implanted in the nucleus pulposus of a nondegenerated L4-L5 disc of a male volunteer 45-years-old and weighing 70 kg. Pres-sure was recorded with a telemetry system during a pe-riod of approximately 24 hours for various lying posi-tions; sitting positions.

Lumbar disc herniation frequently poses a diagnostic dilemma. Approximately 80 % of the population sustains an episode of low back pain in their lifetime. Patients with lumbar disc herniation may exhibit non-specific signs and symptoms such as low back pain and muscle spasm. While the physical exam may reveal that the patient may have a lumbar.

Measurements of intradiscal pressures provide the most direct method of measuring loads on the lumbar spine. Following early examinations to measure disc expansions in vitro10,19, Nachemson 12 proved that the disc was hydrostatic by measuring pressures while rotating a needle in the three principal directions of load. Results: The following values and more were measured: lying prone, 0.1 MPa; lying laterally, 0.12 MPa; relaxed standing, 0.5 MPa; standing flexed forward, 1.1 MPa; sitting unsupported, 0.46 MPa; sitting with maximum flexion, 0.83 MPa; nonchalant sitting, 0.3 MPa; and lifting a 20-kg weight with round flexed back, 2.3 MPa; with flexed knees, 1.7.
This graph describes a person's 'inner' style, the type of behavior that can be expected when they feel completely at ease. Conversely, this style can also sometimes be seen when certain people are placed under severe pressure, because such pressure limits their capacity to adapt their style.

How do you react to pressure situations? Your DISC assessment results show you at least two ways you tend react to pressure. The first option (below) shows the behaviors, based on your DISC style, that appear for you in pressure situations. These behaviors vary from person-to-person depending on their DISC Style. By measurement of intradiscal pressure in vitro, the hydrostatic properties of the nucleus pulposus of normal lumbar intervertebral disc were proven. The hydrodynamic properties seem to exist also in the somewhat degenerated disc, but not in the more severely deranged ones. Intravitally-performed measurements of disc pressure over the last 20 years in more than 100 individuals have.
