Dry needling is a technique used in physical therapy to treat myofascial pain by inserting fine needles especially into myofascial trigger points. These trigger points are hyperirritable areas within tight bands of muscle that cause referred pain and dysfunction. Dry needling treatment seeks to release muscle tension, improve local circulation and reduce pain.In the upper limb, this technique is frequently used in pathologies such as rotator cuff tendinopathies, epicondylitis, carpal tunnel syndrome, among others, achieving a significant improvement in mobility and functionality. The procedure is precise and requires a deep anatomical knowledge to avoid sensitive structures such as nerves or blood vessels. Dry needling is an effective option within a comprehensive physiotherapy approach, complementing other manual techniques and therapeutic exercises.
