Carpal Tunnel Syndrome: Case Reports and Analysis - Ultrasound Imaging and Pathomechanics of Median Nerve Compression

NCT00987571 | Completed

• 1 other identifier: CTS-US Med N JAOA
• Study Type: observational
• Target: 4
• Locations: 0 countries
• Sites: N/A

Brief 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.

Conditions

Carpal Tunnel Syndrome

Keywords

carpal tunnel syndrome; median nerve; ultrasound; electrodiagnosis; Normal subjects

Outcome Measures

Primary Outcomes (1)

• Median nerve compressive narrowing on ultrasound imaging in carpal tunnel syndrome patients

  5 months

Secondary Outcomes (1)

• No median nerve compressive narrowing in normal subjects

  5 months

Study Arms (2)

Carpal Tunnel patients

These patients have documented carpal tunnel syndrome

Normal Subjects

These individuals have no carpal tunnel syndrome

Eligibility Criteria

• Age: 18 Years - 90 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

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

You may qualify if:

• 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.

You may not qualify if:

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