Resolving Back Pain Effectively

Back pain: a worldwide problem

33%
of the European workforce suffer from Lower Back Pain (LBP).¹

Lower back pain (LBP) is a common health problem that interfaces with both quality of life and work performance. It affects 80% of people at some stage in their lives. LBP also results in a significant cost to the employers and economy:

4.6
of productive hours are lost per week in the U.S due to LBP.⁴

12.5%
of total sick days taken in the U.K. is attributed to back pain.¹

7.6 Million
working days are lost in the U.K. due to work-related back pain.⁵

What causes back pain?

To understand the causes of lower back pain amongst office workers, Zgonic and dorsaVi, a specialist in body sensor technology, found that back pain can be caused by:

What is good & poor sitting posture?

Poor sitting postures exacerbate back pain. The relationship between sitting posture and risk of pain may be understood through the impact that posture has on the disc pressure.

Disc pressure in different anatomical positions

50% increase in pressure (from 100kg to 150kg) is applied to the lumbar spine  when an individual moves from a standing position to a supported seating position. The lumbar spine is able to support this amount of pressure.

100% increase in pressure (from 100kg to 200kg) is applied to the lumbar spine when an individual moves from a standing position to a flexed or hunched seating position. The lumbar spine is unable to support this amount of pressure for extended periods of time.

A 200kg pressure is applied on the lumbar disc when workers adopt a flexed position, as illustrated on the right.

Sitting in a neutral position significantly reduces the risk of back pain.

How can Zgo help to alleviate back pain?

In 2013, Zgonic commissioned the bio-medical research organization dorsaVi Pty Ltd to examine existing and prior research into the incidence and causes for the rising levels of the Lower Bank Pain amongst office workers.

dorsaVi which specializes in the study of human movement, was directed to use its ViSafe technology to examine the effects in the lumbar region of computer operators who deviated from neutral posture seated positions.

After studying individuals and their sitting postures at the workplace, Zgonic and dorsaVi concluded that the primary elements needed to achieve a neutral sitting posture are: i) Zgo monitor arm & ii) Ergonomic chair with a dynamic back rest and adjustable seat depth.

In a research carried out by Research Physiotherapist, Rob Laird at the Back Care Centre in Odense, Denmark, a ‘neutral sitting posture’ occurs when the angle of flexion between the pelvis and the lumbar spine is within the range of 16ᴼ – 36ᴼ.

Monitor Stand

The monitor stand dictates sitting posture. It pulls users forward because users have to lean towards the monitor to see the screen clearly. This forces the users to relinquish the critical benefits provided to them through constant contact with the backrest of even the best ergonomic chair available.

In addition to lower back pain, this can also result in poor head and neck support due to unnecessary and excessive head movements when reading.

Zgo Monitor Arm

The Zgo monitor arm features an easy spring-assisted height adjustment of the screen that combines with its three articulation points – base, elbow and display mount. This allows the user to life, reposition, swivel and tilt the monitor easily to any desired orientation.

The Zgo monitor arm is a multi-directional monitor arm solution that helps users achieve a better sitting posture by allowing them to make easy adjustments to the height and depth of the screen while they remain seated comfortably in a neutral position.
