While the one-handed claw is seemingly the most convenient way to grip your device, over prolonged periods of time, it could be doing damage to your wrist and aggravating your ulnar nerve—among other issues.
In an interview with the National Desk, hand surgeon Dr. Steve Beldner said though everyone wants a small, thin device, “Our hand wasn’t designed to handle small objects.” Ideally, instead of zeroing our thumb in on a thin object, which loads the joint unfavorably, we want to “bring the thumb out into what we call abduction or away from the palm.”
To do this, Beldner said, make the device thicker—by propping a rolled up washcloth or t-shirt behind it—to take the stress off the joint. (Presumably, a PopSocket provides some of the same joint relief.) He also suggests keeping your elbow and wrist as straight as possible to allow for better circulation through the nerve.
