Are there any articles on how to fish them? I'm assuming you can shake them while the lure is in one place but are there any other ways to successfully fish these?

deadstick and drag are the most productive methods imho.

A shakey head jig is really a new name for an old concept.

Ain 't that the truth !  ;D

Just like D-shot ( hook above sinker ).  

im new to the shakey head myself but im going to try it tomorow whats dead stik

If you sight fish, and don't care about catching a nesting fish, then the shaky head is the way to go.

Agreed

The key purpose of the shaky worm is for finessing negative bass (winter season, spawning season, post frontal, etc).

In that context, I usually impart one or two short, sharp twitches to kick-start the worm tail,

then let the worm rest in place about 5 seconds (a "true" 5 seconds is deceptively looong).

Jiggling a worm in place offers very poor coverage, so I'll intersperse the twitching with slow dragging to change the lure's scenery.

Oddly, we don't get many strikes during the drag phase, and practically no strikes at all during the fall.

With the shaky worm, most of our pickups occur during the pause, usually right after a twitch.
