Core Tip
Core Tip: Percutaneous electrolysis is a minimally invasive approach frequently used in lower limb musculotendinous pathologies which consists of the application of a galvanic current through a dry needling (DN) or acupuncture needle which acts as a negative electrode, increasing the pH and cellular necrosis by a local electrochemical reaction. However, the current evidence regarding its application in myofascial trigger points (MTrPs) is limited. Therefore, the aim of this study was to assess the efficacy of percutaneous electrolysis compared with DN in patients with unilateral patellofemoral pain syndrome to improve rectus femoris MTrP and patellar tendon pain pressure thresholds, subjective anterior knee pain perception and induced pain during interventions.
