How long does it take for smartphone use to throw off your posture?

Answer: Quicker than anyone realized

Some researchers out of Korea wanted to see what 20 minutes of gaming on a smartphone did to your neck and upper back muscles and posture. So they had 18 men sit upright in an unsupported chair, playing a game on their smartphone that was known to be an engaging game to play. The game is called Anipang; I’ve never heard of it. But, apparently it’s the kind of game that really takes your mind off of where you are and what your posture is doing. The guys sat in an unsupported chair at 90 degree angles between the thighs, the legs, the back. They measured the posture with a digital camera and markers placed on them, and they measured muscle activity of the neck muscles and the trapezius muscle in the neck and in the upper back.

They did these tests in increments of 0 minute, 5 minutes, 10 minutes, and 15 minutes. They stopped the study at 16 minutes because of excruciating pain. Just kidding–they ran out of cheetos. Actually, they did have pain. At the beginning of the study, the average pain experience was 0/10. No pain. At the end of the study, only 16 minutes into game play, they had an average neck pain of 4.2/10, and an average upper back pain of 2.2/10.

What about posture? Their heads practically fell off.

The rate of neck flexion increase was very sharp among subjects as they played the smartphone game, and a significant increase of neck flexion began as early as 5 minutes after the start of smartphone use.

and,

…the timing of substantial neck flexion increase in this experiement occurred much earlier than in the findings of Lee, Park, and Yoo. In most cases of people typing on desktop and laptop computers, the computers are placed on a standard desk and the arms of users are supported on the desk for typing.

People tend to use their phones and iPads unsupported. Or, they have to position themselves into an awkward position to use them. Who using your phone, your shoulders slump. Your neck flexes. Your head extends. You look horrible.

But that’s not all. Bad posture equals increased muscle activity, and tragically, muscles in the upper back that have given up. Your neck goes really tight, and the bones in your upper back start to sit on the ligaments for passive support. You’re not even trying to use your muscles at this point. Your discs and ligaments are taking up the stress of posture. In this study, the muscle activity of the subject’s neck immediately shot up, while the muscle activity of the thoracic (upper back) paraspinal muscles immediately shut off. Along with that, the lower trapezius, responsible for shoulder posture and stability shuts off–getting worse over time.

When your muscles shut off and you are resting on your ligaments and discs, this is known as a flexion relaxation response. This is the theory behind low back pain and degenerative arthritis with constant bad posture.

So with smartphone use, as you develop “text neck”, and you slouch your real body while you play in a virtual world, you almost certainly will start having neck pain in the short term, and will eventually develop arthritis and low back pain in the long term.

This is a study that is relevant to the patients that we see in our chiropractic office in downtown San Francisco. We see a lot of tech workers who are stuck behind a desk, or a laptop, or a smartphone just to get work done. Our patients tend to be younger workers who haven’t had the time to develop arthritis. Because of this, we see a lot of neck pain cases. The first step in taking care of your neck pain is to develop an awareness of your posture at work and at play. If you are spending 16 minutes at a time on your smartphone without support, then you will statistically develop moderation neck pain, and you will have tight neck muscles. The question is, will you pull yourself away and do something about it, or will you grow complacent and let it go?

Is your shoulder pain coming from your neck?

By | Uncategorized | No Comments

Have you been working long hours behind a desk, seated and hunched over? Then you’ve probably felt pain creeping up in your shoulders, or across your shoulders between your shoulder blades.

But is this truly where the pain starts?

The biggest complaint that our patients present us with involve shoulder pain that is actually referred pain from the lower neck. What many people don’t realize is that the tight muscles and trigger points across the shoulders are signs that there are pain signals coming from the neck.

Your upper back may be getting stiff which makes the neck a little unstable, and this refers pain back to your shoulders.

So what can you do about this? You need to mobilize, strengthen, and straighten.

Mobilize your upper back by being in constant motion, stretching appropriately, and taking ten to fifteen minute micro-breaks frequently from work. Getting adjusted with a chiropractor is also an appropriate way to improve movement and unlock the stiff areas in your back.

Strengthen your muscles that support your neck to make you more resilient to pain and postural problems.

Finally, straighten yourself by watching your posture and ergonomics.
