Ultrasound with Shearwave Elastography for Carpal Tunnel Syndrome
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new ultrasound method to detect stiffness issues in the wrist for individuals with carpal tunnel syndrome. The study compares two treatments: surgery to relieve nerve pressure and corticosteroid injections. An FDA-approved ultrasound system with shear wave elastography capability will assess the tissue before and after these treatments. Individuals with wrist pain in only one hand who are already scheduled for either a corticosteroid injection or surgery may be suitable for this trial. Participants will have their wrists scanned before and several weeks after treatment to evaluate progress. As an unphased trial, this study offers participants the chance to contribute to innovative research that could enhance future treatment options for carpal tunnel syndrome.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this ultrasound method is safe for detecting stiffness in wrists?
Research has shown that using ultrasound with shear wave elastography (SWE) is safe for diagnosing and monitoring carpal tunnel syndrome. This non-invasive method does not involve surgery or entering the body. Studies indicate that SWE is highly sensitive and provides detailed information about tissue stiffness without causing discomfort. No reports of negative effects have emerged from using this type of ultrasound.
Corticosteroid injections for carpal tunnel syndrome are also generally well-tolerated. These injections are common and have been used for many years to reduce inflammation and pain. While some individuals might experience temporary soreness or swelling at the injection site, serious side effects are rare.
Both treatments offer safe options for those considering participation in clinical trials.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it explores how shear wave elastography (SWE) can provide detailed insight into tissue stiffness in patients with carpal tunnel syndrome. Unlike traditional diagnostic methods, SWE offers a non-invasive way to visualize changes in the wrist before and after treatments like surgical decompression or corticosteroid injections. This new technique might help doctors monitor recovery more precisely and tailor treatments for better outcomes. By potentially offering quicker and more accurate assessments, SWE could revolutionize how we understand and approach carpal tunnel syndrome.
What evidence suggests that this ultrasound method is effective for detecting stiffness in carpal tunnel syndrome?
Research has shown that a special type of ultrasound called shear wave elastography (SWE) holds promise for examining carpal tunnel syndrome (CTS). This trial will use SWE to assess tissue stiffness in participants receiving different treatments. For instance, participants in the corticosteroid injection arm will undergo SWE measurements to evaluate changes in stiffness six weeks after the injection, indicating treatment effectiveness. Participants undergoing operative treatment will have SWE assessments before surgery and at 3 and 6 months post-surgery. Additionally, combining SWE with other ultrasound methods has resulted in high accuracy for diagnosing CTS. Overall, SWE is becoming a valuable tool for both diagnosing CTS and tracking treatment progress.12567

Experimental Treatment
Shear wave elastography (SWE) will be used to assess the stiffness of tissue. Patients will be revaluated at 3 and 6 months post-operatively. Patient will sit done in a chair. The investigators will scan the wrist area of both arms to acquire SWE map. This imaging will be done before the treatment. We will repeat the imaging study at 3 and 6 months after the treatment. Each ultrasound imaging session will take about less than 10 min. The investigators do not expect any discomfort during the imaging.
