El Paso, TX. Chiropractor Dr. Alex Jimenez takes a look at driving and how it effects the spine.
Daily, nearly 90% of journeys and 92% of miles traveled are made in autos or ground transportation (buses, trucks). On average, guys drive 44 miles as well as girls drive 34 miles each day. For many Americans, driving a motorized road vehicle is their job: truck drivers, bus drivers, ambulance and fire trucks, police, taxis etc.
Modern car and truck layouts have come a long way in their own design over the past 20 years, with better fuel efficiency, better features, better styling and better relaxation. But is there any signs that the look of contemporary bus, car or truck seats and driving might play a part in causing a few of the back injuries that plague Americans each year?
Why Is Driving Different To Ordinary Sitting?
In case your own car is not moving, then sitting in a driving seat probably isn’t substantially different to sitting in a chair that is cushioned, but as soon as the vehicle begins moving things change. Additionally, when driving the feet are actively being used, the right foot on the gas (accelerator) pedal, the left on the brake, and in a stick-shift also on the clutch. When the feet are active they can’t be utilized to support and stabilize the reduced body when they’re put on the floor during regular sitting in a chair, as usually occurs. There is evidence the blend of those variables, coupled with the look of the car seat itself, can increase the possibility of back problems for many people.
Is Driving Linked To Back Problems?
Lab studies have examined the effects of whole-body vibration when a person is sitting in a car seat. The lumbar spine has a natural resonant frequency of 4-5 Hz , and results show that this natural frequency can be excited by lab simulated vehicle driving, and this may result in high spinal loadings in the lower back, and also this in turn could result in greater postural distress and an increased hazard of low back pain and injury.
Quite a few research studies have investigated potential associations between back and driving problems, and usually these studies have found significant consequences.
Drivers in the USA and in Sweden found that in each country 50% of those questioned reported low back pain.
Investigation of the potential reasons for this revealed that long term vibration exposure from driving was among the greatest risk factors for neck, back and low back problems.
Gender generally seems to play an important part in the possibility of developing driving-related back problems. A survey of over 7000 Parisians found that even though severity and the prevalence of low back pain was higher in women, driving was just connected with back problems in guys. The need for driving as a risk factor improved with driving time, and was especially important for guys who drove 4 hours or more each day.
A survey of over 1400 urban transportation system motorists showed that issues using the capacity to accurately adjust the seat that was driving have significant effects on the prevalence of low back problems.
Nevertheless, it appears that driving need not consistently raise the chance of back problems.
Is There An Ideal Car Seat Layout?
Based on a comprehensive evaluation of advice from peer-reviewed scientific journals and texts, automotive engineering reports, and also the National Library of Medicine a string of requirements for the best car seat layout have been developed. Ideally, the optimal car seat should have:
1. Adjustable seat back incline (100 degrees from horizontal is ideal)
2. Changeable seat bottom depth (from seat back to front edge)
3. Adjustable seat height
4. Flexible seat bottom incline
5. Seat bottom cushion with solid (dense) foam
6. Adjustable lumbar support (horizontally and vertically adjustable)
7. Depth pulsating lumbar support to lessen static load
8. Flexible bilateral arm rests
9. Flexible seat back incline (100-degrees from horizontal is optimal
10. Flexible head restraint with pad that is lordosis
11. Frequencies between 1- 20 Hz to dampen
12. Linear front-back seat traveling to allow otherwise sized drivers to reach the pedals
13. Seat back damped to reduce bouncing of the torso in rear end impacts
What To Check For In A Great Car Seat Layout When You Buy The Next Car
It is likely that most automobiles available on the market today won’t have the features listed above that are desirable in the optimal car seat all, but some will have more than others pick wisely. Pay close focus on the subsequent 5 guidelines which should help you to protect your back when you drive.
1) Car Seat Comfort
You’ve fixed this to suit your body and when you sit in the car seat does it feel comfortable. Otherwise, you will be most likely caused by then the car seat rear discomfort issues should you drive for any length of time. Rebound up and down in the seat to find out the way that it adapts vibration. Take the automobile on a test drive.
2) Car Seat Adjustments
Can you correct each of the features of the car seat you want to adjust? At a minimum you need to have the ability to adapt:
- Seat space to accommodate different leg lengths
- Seat height to accommodate different leg lengths
- Backrest angle to sit down in either an upright or more reclined posture
You Should Look For Other Adjustments That Are Useful:
- Seat tilt to angle the front of the seat down or up so that this does not press against the back of your knees
- Look for a car seat that supplies you with great low back support that can be corrected for depth (frequently the seat has an inflatable cushion) and is height adjustable
- Headrest for neck support
- Arms rests which are broad, cushioned and comfortable, and preferably height flexible
3) Shift Your Position
Remember to go your position from time to time. Wait until driving conditions are right to enable you to wriggle in the seat to relieve postural fatigue.
4) Take Breaks
Driving is exhausting work and to prevent driver fatigue and minimize postural discomfort it is good move around and take to pretty frequent rest breaks that enable you to stand up.
You can select a number of car seat accessories that will enhance seat comfort for you personally, from fleece covers to soften the seat to bead backrests to provide for some type of back massage while you drive. Select anything you find adds to your driving comfort.
