 Although dry needling originally utilized only hypodermic needles due to the concern that solid needles had neither the strength or tactile feedback that hypodermic needles provided and that the needle could be deflected by "dense contraction knots", those concerns have proven unfounded and many healthcare practitioners who perform dry needling have found that the acupuncture needles not only provides better tactile feedback but also penetrate the "dense muscle knots" better and are easier to manage and caused less discomfort to patients.For that reason, both the use of hypodermic needles and the use of acupuncture needles are now accepted in dry needling practices.Ofttimes practitioners who use hypodermic needles also provide trigger point injection treatment to patients and therefore find the use of hypodermic needles a better choice.
