triggerpoints and tens

As an ATC I am able to use TENS on my athletes, and today I combined tens on the trigger points on the flank (back)with manual therapy to the opposing limb muscles of the posterior leg.  AMAZING releases. I am wondering if anyone else has experienced this, and if there are other modalites you all like to use, (such as hot rocks, and cool rocks and crystals) that they have gotten great results working trigger points and body trains simutaneously?
