A Comparative Study of Two Dry Needling Interventions for Plantar Heel Pain

Physical therapy approaches continue evolving. During the last years, minimally invasive techniques such as percutaneous needle electrolysis (PNE) was being developed, obtaining promising results for tendon pathology. PNE technique is a minimally invasive treatment that consists of an application of a galvanic electrolytic current that causes a controlled local inflammatory process in the target tissue. This allows for phagocytosis and the subsequent regeneration of the affected tissue. Nowadays, PNE is being used in clinical practice to manage MTrP, but there are no studies supporting that they have an additional beneficial effect over DN. From a biological point of view, it seems reasonable to ascertain that a patient will obtain benefits thanks to the mechanical effects provided by the needle and that patients may benefit more if the electrolysis effect is added to the mechanical stimuli provided by the needle. Therefore, the aim of this randomized controlled study is to compare the effectiveness of DN versus PNE for the level of pain in patients suffering from PHP.
