- What it is
- A retrospective review of electrodiagnostic reports from 866 patients with suspected carpal tunnel syndrome or cervical radiculopathy at a Taiwan tertiary hospital, sorted into four groups.
- How much weight it carries
- Peer-reviewed, but retrospective and from one tertiary hospital, where referrals are not typical of all patients. The four groups are a snapshot of a referred population, not a community rate.
Facts taken from this source
- In the same Taiwan hospital review, 26 percent had double crush syndrome, carpal tunnel syndrome and cervical radiculopathy together.
“151 (20%) patients were diagnosed to have sole cases of CTS; 362 (47%) patients were diagnosed to have sole cases of CR; 198 (26%) patients were diagnosed to have DCS, while 54 (7%) patients had mere symptoms.” (Results)
- In the same Taiwan hospital review, 47 percent had cervical radiculopathy alone, without carpal tunnel syndrome.
