Foot traveler,
A detailed history and careful physical examination, supplemented if necessary by magnetic resonance imaging, can differentiate a herniated lumbar disc from low back strain and other possible causes of similar symptoms. The first assessment in the physical examination is a search for any external manifestations of pain, including an abnormal stance. The patient's posture and gait is examined for sciatic list, which is indicative of disc herniation. The spinous processes and interspinous ligaments are palpated for tenderness. The range of motion should be evaluated. Pain during lumbar flexion suggests discogenic pain, while pain on lumbar extension suggests facet disease. Ligamentous or muscular strain can cause pain when the patient bends contralaterally. Specific movements and positions that reproduce the symptoms should be investigated during the examination to help determine the source of the pain. For example, the upper lumbar region (L1, L2 and L3) controls the iliopsoas muscles, (Known as the tenderloin in animals!), which can be evaluated by testing resistance to hip flexion. While seated, the patient should attempt to raise each thigh while the physician's hands are placed on the leg to create resistance. Pain and weakness are indicative of upper lumbar nerve root involvement. The L2, L3 and L4 nerve roots control the quadriceps muscle, which can be evaluated by manually trying to flex the actively extended knee. The L4 nerve root also controls the tibialis anterior muscle, which can be tested by heel walking. There is more to this evaluation, but what I have written is just to briefly explain that it is not just
