Core stability focuses on maintenance of neutral spinal alignment, optimal trunk position, and the transfer of loads along the kinetic chain. A variety of assessment tools can be utilized to evaluate core stability. A multifaceted approach is recommended utilizing tests for muscle recruitment, endurance, neuromuscular control, and fundamental functional movement patterns. Core stability should be trained in a progressive fashion, beginning with local muscle recruitment, moving to core stabilization in a variety of postures, and then transitioning into total body dynamic movements.
