About this study

Official title: Treatment Monitoring of Carpal Tunnel Syndrome Using Shear Wave Elastography: A Pilot in Vivo Study

This study is being done to test a new ultrasound method to detect possible stiffness problems within wrist(s). The purpose of this research is to the test the effectiveness of a new ultrasound method to check the nerve and surrounding tissue in both wrist of patient volunteers before and after treatment.

Read the detailed description

The ultrasound system is FDA approved. The risks associated with this research study are not beyond the normal risk of conventional ultrasound and should not cause you any discomfort. Ultrasound at the intensity levels and duration used in this study has not been shown to present risk to humans. The investigators will conduct the SWE study on the set time point when the patient returns for follow-up after the therapy (surgical decompression or corticosteroid injection).

A set of pictures will be taken of patients wrists by the FDA approved ultrasound system. This system uses a special type of ultrasound for imaging your wrists.

The ultrasound study will be repeated after 3 and 6 months after the treatments.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • FDA approved ultrasound system with shear wave elastography capabilityDevice

    The investigators will acquire at least 4 acquisitions for each of 2 locations on the wrist. The objective is to correlate SWE measurements with patient-reported measures of symptom severity and functional status scores and severity of pre-operative electrodiagnostic tests (EDX). Evaluate the treatment response to surgical decompression or corticosteroid injection, using quantitative SWE and correlate the results to repeated patient reported outcomes with Boston CTQ, and objective clinical improvement with Semmes-Weinstein monofilament evaluation for recovery of sensibility, and grip and lateral pinch strength.

Study groups in NCT04804293
Study groupRoleWhat they receive
Operative treatment (surgical decompression) for carpal tunnel syndromeExperimentalShear 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.
Receives: Device: FDA approved ultrasound system with shear wave elastography capability
Corticosteroid injection treatment for carpal tunnel syndromeExperimentalShear wave elastography (SWE) will be used to assess the stiffness of tissue. Patients will be revaluated after 6 weeks following corticosteroid injection. Patient will sit done in a chair. The investigators will scan the wrist area of both arms to acquire SWE map. The investigators do not expect any discomfort during the imaging.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Evaluate the treatment response by shear wave elastography (SWE)

    Evaluate the treatment response to surgical decompression or corticosteroid injection, using quantitative SWE and correlate the results to repeated patient reported outcomes with Boston CTQ, and objective clinical improvement with Semmes-Weinstein monofilament evaluation for recovery of sensibility, and grip and lateral pinch strength.

    Measured: First 3 months

Secondary outcomes (1)
  1. Correlate shear wave elastography (SWE) measurements with patient-reported measures of symptom severity and functional status scores and severity of pre-operative electrodiagnostic tests (EDX) elasticity

    Determine the severity and patient outcome scores in patients with symptoms of CTS and Correlate the symptom severity and functional status assessed by the Boston Carpal tunnel Questionnaire (CTQ)21 validated patient outcome scoring profile) in patients with diagnosis of carpal tunnel syndrome with SWE determined median nerve (MN) stiffness.

    Measured: 3 to 6 months

Questions about this trial

What is this clinical trial studying?

A study testing FDA approved ultrasound system with shear wave elastography capability in people with Carpal Tunnel Syndrome, run by Mayo Clinic at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: enrolling by invitation, as of the sponsor's last update on 21 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Evaluate the treatment response by shear wave elastography (SWE) (time frame: First 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Jan 2026.
