How do Electronics Affect Your Posture?

The proliferation and use of PDAs & touchscreen smartphones, and the significant increase in time spent at computer keyboards or engaging in video gaming has created a whole new generation of people of all ages experiencing RSI(Repetitive Stress Injury). More and more, people are depending on these devices to stay in touch with friends and family. However, an increasing number are beginning to pay the price for such ready access to the world.

As mobile phone technology develops, mobiles are getting smaller, with buttons closer together. Small, fine movements tend to aggravate more than larger movements-this coupled with the smaller buttons can lead to injury as smaller buttons are harder to activate.

When you are text messaging, you tend to hold your shoulders and upper arms tense. This cuts down the circulation to the forearm, when in fact it needs a greater than normal blood flow to achieve the fine movements of the thumbs and fingers.

One of the commonest RSIs, popularly called “Blackberry Thumb” occurs because these devices rely almost solely on the use of your thumbs (not all of your fingers) for typing. Any device that relies on the thumbs for typing can cause this type of injury because the thumbs simply weren’t designed for such use. Additionally, there are also other stress injuries reported — wrist, forearm, shoulder, upper back and neck — as a result of constant texting.While it’s hard to use mobiles & tablets in the same way you’d use a computer, the risks of injury are the same – Repeated motion, Unnatural postures and Bright screens, can all cause injury if you aren’t careful.

The problem with smartphones and tablets is that you can literally use them in a million different positions—most of which probably aren’t very good for your body.

Tips to Follow

  • Holding your mobile/tablet flat is bad for your neck, but holding it completely perpendicular is bad for your wrists. As such, you’ll want to compromise by holding it at a 30 degree angle when you’re typing or using the touch screen. If you’re just reading, you can position it more perpendicular, at whatever angle makes it easy to see.
  • Tap lightly on the keyboard. Many people have a tendency to tap very hard on touch screen keyboards because they lack tactile feedback, like real physical keyboards do, and this is bad for your fingers, wrists, and forearms. If you’re typing something longer than just a few sentences at a time, it’s probably worth investing in a Bluetooth keyboard.
  • As you type or use the touch screen, be sure to keep your wrists straight, while keeping your arms and fingers loose and relaxed.
  • Avoid eye strain by making the font larger when possible. If you’re using a program that doesn’t allow you to set the font size, you can buy glasses specifically made for reading tablet displays. If you’re doing a lot of reading, try eye-friendly E-Ink readers like the Kindle or Nook as opposed to the iPad or Kindle Fire.

Its best to…

  • If texting starts to hurt. Stop. Use the other hand or call instead
  • Vary the hand you use
  • Vary the fingers you use
  • Don’t text for more than a few minutes without a break
  • The best option when it comes to touchscreen phones is to use a Stylus while using the phone, as it uses larger muscle groups compared to using only a finger. Hold the stylus like you would hold a pen.

The biggest sufferers are college students and young adults. Plus, there’s not enough attention paid to ergonomics. RSI is preventable. It happens because it’s not taken seriously.

And an increase in miniaturization, and decreased usability–rates of aching thumbs among today’s people is likely…to swell.
