Poor posture while using smartphones may cause neck, upper back pain

April 17, 2017

Poor posture during prolonged use of smartphones and other handheld devices may be related to the increase in patients suffering from neck and upper back pain noticed by spine surgeons, a recent report said.

Some patients, particularly young patients who shouldn’t have back and neck issues yet, are reporting disk hernias and alignment problems, the study authors wrote.

“In an X-ray, the neck typically curves backward, and what we’re seeing is that the curve is being reversed as people look down at their phones for hours each day,” said study coauthor Dr. Todd Lanman, a spinal neurosurgeon at Cedars-Sinai Medical Center in Los Angeles.

By the time patients come to him, Lanman said, they are already in bad pain and have disc issues, he said. “The real concern is that we don’t know what this means down the road for kids today who use phones all day.”

Lanman and co-author Dr. Jason Cuellar, an orthopedic spine surgeon at Cedars-Sinai Medical Center, wrote that people often look down when using their smartphones, particularly when texting as compared to browsing online or watching videos. Previous studies have also found that people hold their necks at around 45 degrees, and it becomes even worse as they sit, versus standing, the study team writes.

The impact on the spine increases at higher flexed postures, they add. While in a neutral position looking forward, the head weighs about 10 to 12 pounds. At a 15-degree flex, it feels like 27 pounds. The stress on the spine increases by degree, and at 60 degrees, it’s 60 pounds.

“For today’s users, will an 8-year-old need surgery at age 28?” Lanman said, adding that they are not sure what to expect or if this issue could change normal anatomies of kids who have spines that are still growing and not developed.

Lanman and Cuellar suggest simple lifestyle changes to relieve the stress from the “text neck” posture. They recommend holding cell phones in front of the face, or near eye level, while texting. They also suggest using two hands and two thumbs to create a more symmetrical and comfortable position for the spine.

Beyond smartphone use, the spinal surgeons recommend that people who work at computers or on tablets use an elevated monitor stand so it sits at a natural horizontal eye level. With laptops, they recommend a similar adaptation by using a separate keyboard and mouse so the laptop can be at eye level and still create a good ergonomic position while typing.

“It is difficult to recommend a proper posture for smartphone users. If we raise the phone at eye level to avoid the look-down posture, it will add new concerns for the shoulder due to the elevated arm posture,” said Gwanseob Shin of the Ulsan National Institute of Science and Technology Ergonomics Lab in South Korea, who wasn’t involved with the study.

He recommends frequent rest breaks or some physical exercise that can strengthen the neck and shoulder muscles. He also said that some apps can give alarming signals to users to avoid prolonged looking-down posture.

Lanman recommends stretches and basic exercises that focus on posture as well. He tells patients to lie on their beds and hang their heads over the edge, extending the neck backward to restore the normal arc in the neck. While sitting, he recommends aligning the neck and spine by checking that the ears are over the shoulders and the shoulders are over the hips.

“Ask your friend to take a photo of your upper body when you’re texting, then use the picture as the background image on your phone,” Shin said. “That will remind you to take breaks frequently. Even a short break of a few seconds – called a micro-break – can help our tissues recover.”
