A leg stretch test for lower back nerve pain
Part of Brain & nervous system clinical trials.
This study tests a simple leg-stretching test to see if it can help doctors tell which nerve root is causing your leg pain. If the test works, it could make diagnosing and treating nerve pain faster and more accurate.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have pain that comes from one of the L2, L3, or L4 nerve roots in your lower back (your doctor can confirm this).
- You are scheduled to have a steroid injection in your lower back to treat that pain.
- You do not have diabetes or another condition that causes nerve damage.
- Your pain is only from those specific nerve roots, not from other parts of your lower back.
- You are not pregnant and do not have an active infection.

This study checks how well the straight leg raise test can find the exact nerve causing your leg pain by comparing it with a targeted nerve block injection. It may help if you have leg pain from a pinched nerve in your lower back.
This study tests whether combining three physical therapy techniques—spine mobilization, leg movements, and spinal traction—can reduce pain and improve function in people with pinched nerves in the lower back caused by a bulging disc. If it works, it could offer a non-surgical treatment option.
This study tests whether specific leg exercises, called nerve gliding exercises, can reduce leg pain and improve balance and movement in people with a slipped disc in the lower spine that causes pain down one leg. It may be a good option if you haven't had spinal surgery or recent steroid injections.
This trial compares two types of physical therapy for low back pain and leg pain caused by nerve irritation (called lumbar radiculopathy). One group gets standard spinal movement treatment, and the other gets that treatment plus a technique called 'neural flossing' that helps the nerves slide smoothly. The goal is to see if adding neural flossing gives better pain relief and improvement.
This study compares two gentle hand techniques (Maitland and Mulligan) to see which one better relieves leg pain from a pinched nerve in the lower back. If you have chronic sciatica-type pain, these treatments may help without surgery.
This trial tests a new type of treatment (high-voltage pulsed radiofrequency) that uses a special needle to deliver energy to the nerve root in your lower back. The goal is to see if it can reduce chronic leg pain caused by a pinched or irritated nerve.
