Dry needling is a minimally invasive therapeutic technique in which fine, sterile needles are inserted into myofascial trigger points, tight muscles, or connective tissue to relieve pain, reduce muscle tension, and restore normal function. By mechanically stimulating these points, the therapy can release muscle knots, improve blood flow, and promote local tissue healing and neuromuscular relaxation. Clinically, dry needling is applied in musculoskeletal rehabilitation to manage conditions such as chronic muscle pain, shoulder or hip dysfunction, tendonitis, and sports-related injuries. It can also support post-surgical recovery and enhance mobility and functional performance in patients undergoing physical therapy programs.
