This article popped up on my newsfeed in Twitter (@BrkwoodPhysio) and it gives us a really nice insight into the use of Dry Needling in dancers.  

Dry needling is a technique used for treating tension within muscles.  The insertion of the needle into the area of tension causes the muscle to twitch, which is followed by relaxation of the tensioned area.  Now, it can be an uncomfortable technique, and there may be a degree of post treatment soreness.  In my opinion, it would not be recommended in a situation where a dancer or anyone needed to perform or compete the next day, due to the post treatment soreness, that may occur.  I would recommend scheduling an appointment up to a week in advance of performance to allow plenty of recovery time and rehearsal time prior to performance.
