Contrary to popular belief, spooning is not always the best sex position for those with a bad back.
Using infrared and electromagnetic motion capture systems – like those used in the creation of video games – scientists tracked how 10 couples’ spines moved when attempting five common sex positions.
They found that sex positions that are suitable for one type of back pain aren’t appropriate for another kind of pain, and suggest new positions or techniques based on what movements trigger a patient’s symptoms.
