Effect of Neck Retraction Taping on Forward Head Posture in Computer Work (2013)

I wish there were photos to show the tape placement.

Has anyone had luck with this or other techniques for correcting their forward head posture?

Basically- taping your back so that you know when you're leaning fwd.

Here are some other good techniques:

(these have been very helpful in my case)

This is pretty relevant for me, given that in the last two days my hands/arms have gone completely numb. Does anyone have any other links/tips for keeping or correcting good posture?

What was the effect on eye strain?

I would like to know this as well. I stopped having eye strain after I started using f.lux and turning down the brightness on all screens.
