The researcher behind the smartphone “horns” study sells posture pillows
Recently, news coverage of a scientific study has suggested that craning to read a smartphone may even contribute to the growth of “horn-like” bone spurs on the base of the skull.
If you’re skeptical, you have good reason: Scientists and journalists have called out the study for its dubious methods, which examined x-rays for evidence of tilted necks and skull spurs. There’s plenty to dispute in the paper’s design and conclusions. But aside from the science itself, there’s another reason to question the paper’s conclusion: the lead author’s business ventures.
David Shahar, one of the study’s authors, is a chiropractor and biomechanics PhD. So when it came time to find the 1,200 participants for his research, he didn’t look far: Based on the data associated with the paper available on his university’s website, every one came through his own chiropractic practice in Australia. That detail isn’t in his paper, which only refers to participants chosen from a clinician’s database.
That clinician is Shahar, who, along with his spouse and business partner, treat what they call a “poor posture epidemic” with digital posture analyses and on-site x-rays. In an email to Quartz, Shahar declined to comment when asked directly if the participants were coming through his practice. Instead, he said that about half of the young adults in his “original research were asymptomatic participants who were recruited by another researcher for a different project,” but did not elaborate on their specific ages or number of these participants.
If you really wanted to get a look at the effects of smartphone use on neck health, you’d want data from the general population, not people who were already concerned about neck or back pain. The paper acknowledges that issue, and excludes any patients who reported severe neck pain. But it doesn’t state that the patients came from Shahar’s personal practice, who may have skewed the data because they explicitly sought help with their posture.
Shahar is also the creator of Dr. Posture, an online store that advertises information and products related to forward head posture. One section tells users how to “look and feel your best in three easy steps,” which include watching a video by Shahar, downloading at-home exercises, and sleeping with a Thoracic Pillow, which Shahar has trademarked and sold for $195.
