The Straight Leg Raise test, also known as the Lasegue test, is a simple diagnostic test used to assess for nerve root irritation or compression in the lower back.
It involves lifting the patient's straightened leg while they are lying on their back to see if it reproduces leg pain.
This test is commonly used to diagnose conditions such as sciatica, herniated discs, and spinal nerve root compression. It can also help assess hip flexibility and identify potential causes of lower back pain.
The main purpose of the Straight Leg Raise test is to identify the presence of nerve root compression in the lumbar spine.
By eliciting pain or discomfort when the leg is raised, healthcare providers can pinpoint the source of the issue and determine the appropriate course of treatment.
This test is particularly beneficial in diagnosing conditions like sciatica, herniated discs, and spinal nerve root compression. It helps healthcare providers understand the extent of the nerve impingement and develop a treatment plan tailored to the patient's needs.
The Straight Leg Raise test can also be used to assess hip flexibility and identify any limitations that may contribute to lower back pain.
By performing this test, healthcare providers can gather valuable information about the patient's musculoskeletal health and overall mobility.
The cost of a Straight Leg Raise test in India can vary depending on the healthcare facility, location, and additional services included in the assessment.
On average, the price range for this test can be between INR 500 to INR 2000.
Factors that can influence the cost of the Straight Leg Raise test include the expertise of the healthcare provider, the complexity of the case, and any additional imaging or diagnostic tests that may be required.
Patients should consult with their healthcare provider to get a clear understanding of the total cost involved.
The Straight Leg Raise test is considered normal when the patient can raise their leg between 30 to 70 degrees without experiencing any pain or discomfort.
If the leg can be raised beyond 70 degrees without pain, it is considered a positive test result.
Here is a table showing the ranges and their meanings:
Range |
Meaning |
0-30 degrees |
Negative test result |
30-70 degrees |
Normal test result |
>70 degrees |
Positive test result |
High Straight Leg Raise test levels, where the leg can be raised beyond 70 degrees without pain, indicate nerve root compression or irritation in the lumbar spine.
Low Straight Leg Raise test levels, where the leg cannot be raised beyond 30 degrees without pain, indicate normal test results. This suggests that there is no nerve root compression or irritation present in the lumbar spine.
The straight leg raise test is used to check for herniated discs or nerve root compression in the lower back. If raising the leg reproduces pain, it suggests nerve irritation or compression, helping to diagnose the cause of back pain.
The straight leg raise test can help detect conditions like sciatica, herniated disc, or spinal stenosis.
During a straight leg raise test, you lie on your back, and a healthcare provider lifts one of your legs while keeping it straight to assess for any signs of nerve irritation or disc herniation in your lower back.
A positive straight leg raise test result typically indicates irritation or compression of the sciatic nerve, suggesting conditions like a herniated disc or sciatica.
During a straight leg raise test, you may experience some discomfort or mild pain in your lower back or legs, but it should not cause any serious risks.
Yes, the straight leg raise test is commonly used to help diagnose sciatica.
The straight leg raise test is a commonly used test to help diagnose lumbar disc herniation. It is a simple and quick test that can provide valuable information to your healthcare provider.
Yes, the straight leg raise test can potentially cause strain in the leg muscles if done too forcefully or aggressively.
The straight leg raise test may not be accurate in diagnosing all causes of lower back or leg pain. It may not provide a complete picture of the underlying issue.
