Dry Needling or Percutaneous Electrolysis for Managing Myofascial Trigger Points?

Dry needling (DN) and percutaneous electrolysis (PE) are minimally invasive physiotherapy techniques commonly used for the management of myofascial trigger points. DN consists of inserting a fine filiform needle into a hyperirritable area within a taut band of skeletal muscle, with the aim of eliciting local twitch responses and reducing myofascial pain. PE follows a similar needle-based approach but combines the mechanical stimulus of the needle with the application of a galvanic electrical current, producing an electrochemical reaction in the targeted tissue. Both techniques have been increasingly used in clinical practice for musculoskeletal pain conditions, including shoulder pain, although the evidence comparing their relative effectiveness remains limited. Shoulder pain is one of the most prevalent musculoskeletal disorders and is frequently associated with the presence of active myofascial trigger points. Among the shoulder muscles, the infraspinatus has been identified as a clinically relevant structure because its trigger points may reproduce referred pain patterns commonly reported by patients with shoulder symptoms and may contribute to pain, reduced strength, altered mobility, and functional disability. Previous studies have suggested that invasive treatment of infraspinatus trigger points may produce short-term improvements in pain sensitivity and shoulder-related symptoms. However, most available research has examined dry needling or percutaneous electrolysis s…
