Superficial and deep dry needling are two common approach used in treating Myofascial trigger points. But, I wonder any articles published on differentiating those techniques by giving reference value of depth of penetration?
The references given for the Aamir colleague are quiet good.
Nextly I´ll get to publish in Manual Therapy about the evidences of dry needling in cervical muscles at C3 Level regarding to the Deep needling. I´m waiting to the autorization.
I´ve attached the draft paper in advance. I hope it´s interested for you.
