A positive Kemp's test is indicated when a patient experiences pain, numbness, or tingling during the test, specifically in the back or lower extremities, and on the side being tested.
Understanding Kemp's Test
Kemp's test is a physical examination maneuver used primarily to assess for the presence of lumbar spinal issues. It is usually performed by a healthcare professional, like a physical therapist or physician. The test involves the patient extending and rotating their spine, thus compressing the facet joints and nerve roots.
How the Test is Performed
The patient is typically asked to stand, and the examiner will then support the patient's trunk while guiding them into:
- Extension (bending backward).
- Rotation (twisting to the side being tested).
- Lateral flexion (bending to the side being tested).
Positive Test Result
According to the provided reference, a positive test result occurs when:
- The patient reports experiencing pain, numbness, or tingling.
- These symptoms are located in the back or lower extremities.
- The pain is felt on the same side of the body as the side being tested.
- For instance, if the patient rotates and bends to the right and feels pain on the right side, this would be considered a positive test for the right side.
What a Positive Test Indicates
The location of pain can suggest different underlying issues:
- Local Pain: If the pain is felt solely in the lower back area, it may indicate a problem with the facet joints, which are small joints between the vertebrae.
- Radiating Pain: If the pain radiates down into the leg, it suggests nerve root irritation or compression which could indicate conditions like a herniated disc or spinal stenosis.
Summary Table
| Symptom | Location | Possible Implication |
|---|---|---|
| Pain, Numbness, or Tingling | Back or lower extremities | Positive Kemp's Test |
| Local Pain | Lower back | Facet Joint Issue |
| Radiating Pain | Leg | Nerve Root Irritation, possible herniated disc |
Importance of Medical Evaluation
A positive Kemp's test is not diagnostic on its own. It's essential to correlate the findings with other clinical information, imaging (like MRI or CT scan), and a patient's history to make an accurate diagnosis and determine an appropriate treatment plan.
