Trial summary

Carpal tunnel syndrome is caused by compression of the median nerve at the wrist. The hypothesis is that ultrasound imaging can be used to visualize nerve compression in carpal tunnel patients during hand activity, and normal subjects will not demonstrate any nerve compression.

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 90 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: Adult patients with upper extremity symptoms of pain, numbness, and tingling; Adult subjects with no upper extremity pain, numbness, or tingling

Who may be able to join

  • Patients must have symptoms consistent with carpal tunnel syndrome and electrodiagnostic testing that demonstrates abnormal median nerve function at the wrist, consistent with carpal tunnel syndrome.
  • Normal subjects must have no upper limb symptoms to support carpal tunnel syndrome and normal nerve testing.

Who cannot join

  • Patients excluded if nerve testing was not consistent with carpal tunnel syndrome.
  • Normals excluded if nerve testing demonstrated any median nerve abnormality.

About this study

Carpal tunnel syndrome is caused by compression of the median nerve at the wrist. The hypothesis is that ultrasound imaging can be used to visualize nerve compression in carpal tunnel patients during hand activity, and normal subjects will not demonstrate any nerve compression.

Read the detailed description

Two patients with carpal tunnel syndrome underwent nerve testing to document that they had median nerve abnormality at the wrist. They subsequently had ultrasound imaging of the wrist at rest and during a stress test using hand activity. Two control subjects had nerve testing to prove that they had no nerve abnormality at the carpal tunnel. The carpal tunnel syndrome patients demonstrated nerve compression on the ultrasound images during the stress tests and the normal subjects showed no nerve compression.

Questions about this trial

What is this clinical trial studying?

An observational study of Carpal Tunnel Syndrome, run by EMG Labs of Arizona Arthritis & Rheumatology Associates.

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 2 inclusion and 2 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: finished, as of the sponsor's last update on 1 Oct 2009. Status can change between updates, so confirm with the study contact before making plans.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Median nerve compressive narrowing on ultrasound imaging in carpal tunnel syndrome patients (time frame: 5 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 1 Oct 2009.
