Fig. 6From: Co-contraction characteristics of lumbar muscles in patients with lumbar disc herniation during different types of movementAnalysis of agonistic and antagonistic muscle activities between LDH and healthy control during different types of movement. a Forward bending movements, b backward bending movements, c left lateral flexion actions and d right lateral flexion actions. (NB: heights of the agonist and antagonist are the sum of AEMG values for corresponding muscle activities during each type of movement. **Significant at 0.01 level.)Back to article page
