In an age where we can divert most of our attention to our phones, and still be able to walk at the same time, I start to wonder whether our arm swing is still relevant. Is it becoming a less than necessary motor skill in society and hence the need the rehabilitate it?
The answer is no.
Try this – walk at your normal pace and hold your phone up and look at it as if you are reading. Then pick up your walking pace and start breaking into a run. The faster you go, the more you have to let your phone down and swing your arms with your legs.
