They found that the joint moments measured at any given motion increased with greater magnitudes of joint displacement, and were significantly larger in the two most caudad facet joints (L4 L5 and L5 S1).62 With lateral bending, strains of the joint capsule tended to be larger in magnitude in the three most caudad joints(L3 S1) during contralateral flexion (i.e., the left facet joints are most strained during right lateral flexion),whereas the two most cephalad joints (L1 L2 and L2 L3)bore the greatest strain during bending to the ipsilateral side.
