RLE Massage Therapy Neuromuscular Integration & Structural Alignment (NISA) NISA aims to stretch, loosen, and soften the body's fibrous tissues that surround the muscles and organs in our bodies. NISA is an important technique designed to restore function and to maintain muscle elasticity. NISA aims at affecting the fascia, a broad system of fibrous tissue bands found in the body. The fascia is interconnected throughout the body (nerves, muscles, blood vessels, and organs.) If the fascia contracts the body suffers from lessened energy, blood flow, and motion. NISA helps to improve such detrimental physical conditions.
