Why is movement so important?
The spine is designed in a highly adaptive way. It facilitates movement and weight distribution. However, spinal pain is a natural response to sedentary work and lifestyle. Both ergonomic and personal related predisposing factors will be indicative of spinal pain development, but chronicity of the pain is also dependent on psychosocial variables.
Mechanical load plays a significant etiological role in the development of LBP. Prolonged positioning in general leads to increased static load through the joint complex and surrounding soft tissue. I get asked every day if I think someone should buy a standing desk. The truth is standing and sitting both have specific pros and cons for mobility, exertional force, circulatory demands, energy consumption, coordination, and motion control. There are some benefits for standing, with indication for increased cardio-metabolic functioning, and potential engagement and performance in work related tasks. Sitting inevitably encourages inactivity (increased risk for obesity), accumulation of metabolites, and progression towards degenerative changes in the spine with an increased potential for disk herniation later-on. Of course, driving for prolonged periods can be a contributing concern for your neck, lower back, and upper extremities. Vibration from the moving vehicle also adds another layer of stress to your spinal system. Whilst I say all of this, there has been some research to indicate that simply implementing exercise alone proves more effective than modifying your ergonomic environment. The key is to ensure implementation of postural cues, strategies and ensure movement is consistent through your daily activities to offload structures compromised by static load.
Prolonged positioning in general should be avoided where possible and lumbar support should be encouraged with quality seating and/or lumbar support modalities that can be put in place for your work setup and vehicle.
Mitigation of spinal injury in the work environment pertains to due diligence and actively avoiding awkward positioning and heavy lifting. Common sense prevails, just ask your physio!
