Figure 3 From: Increased multiaxial lumbar motion responses during multiple-impulse mechanical force manually assisted spinal manipulation Mean percent change (maximum multi-impulse value compared to first impulse) in low force, segmental (L1, L2) and intersegmental (L1–L2) acceleration responses for the medial-lateral (ML), posterior-anterior (PA), and axial (AX) axes. Asterisks (*) indicate significant change from first impulse.Back to article page
