Let's face it, doing exams is a pain. However, as part of patient care, they are necessary. Following a good consultation, a thorough exam will help you confirm your suspicions and document the patient's condition.
When a patient has no lower back irritation, they will often sit right up after treatment - with no limiting pain or obvious discomfort. Amoss' sign can be noted when the patient has pain rising from a reclined position. If they are lying supine, they may turn to the side and use their arms to push themselves upright. The sign is considered positive if the patient indicates thoracic or thoracolumbar pain with the action of sitting up. This finding may indicate a spinal strain/sprain, intervertebral disc syndrome or ankylosing spondylitis. Obviously, this is not a stand-alone diagnostic test. Other testing should be done before you get to this point, but if you have complaints of pain and other positive tests, this is one more diagnostic finding you can add to your list of findings.
If the patient is in a seated position or has risen from lying down, watch how they rise to a standing position. If the patient has complained of lower back pain or sciatica, they may rise by balancing on the unaffected leg and favoring the side of complaint. Such an observation is considered a positive Minor's sign. They also may use one hand to hold the lower back and the other to push up from the table - also helping to reduce stress on the lower back. Again, this is an observed finding, not a physical test you perform, so watch your patient. This finding should be present with any lower back injury that causes muscular splinting in the lower back, including sacroiliac lesions, lumbosacral strains and sprains, disc syndromes, etc. The degree of restriction will vary depending on the degree of the severity of the pathologic process.
Another way to use these tests is to evaluate for malingering. Some patients may present with acute symptoms such as guarding all motion and screaming in pain during orthopedic testing, but then sit up and rise with no apparent discomfort. Such an observation should be a red flag for a patient that is not being entirely truthful about how they feel. Such a finding warrants further testing, evaluation and possible referral for accurate assessment.
As all you have to do is watch how the patient moves. It should be easy to add these tests into your exam protocol. Certainly, there are other tests, signs and observations to be made in individual cases. The more information you have to confirm your findings, the more secure you are in your diagnosis and treatment protocol. These extra notes help document the severity of your patients' complaints and show the progressive response to care. This extra documentation also can help make the difference if you must justify your diagnosis to an insurer or third party. Take the extra few seconds to add these tests into your exam routine - they will serve you well.
