<>Neurologic examination of the lower extremities includes strength, sensation, and reflex testing (Table 3), even in the absence of significant sciatica. A straight leg raise test is positive for L4-S1 nerve root pain if it radiates below the knee. A reverse straight leg raise test (extending hip and flexing knee while in the prone position) is positive for L3 nerve root pain if it radiates into the anterior thigh. A central, paracentral, or lateral disk herniation may affect different nerve roots at the same level. Examination of the lumbosacral, pelvic, and abdominal regions may provide clues to underlying abnormalities relating to back pain (Table 15,6 and 25,6,8). >
<>2010 — Updated: Added a very beefy footnote about some new research showing that muscle imbalance does not result in higher rates of injury. This almost should have been a new section, but I decided to just make it a ginormous footnote — footnotes are there for delving if you want to, that’s the idea! You can read a summary of the research in the bibliography (see Hides et al), but the relevance to back pain is spelled out in detail here. And it’s interesting. [Section: Diagnosis: Your low back is not fragile!] >
<>Some people may need prescription-strength NSAIDs or opioid medications to help with pain. It is important to talk to your doctor or pharmacist if you are taking any other medications -- including over-the-counter medicines -- to avoid overdosing on certain active ingredients. Your doctor may also prescribe muscle relaxants to help ease painful muscle spasms. >
