The assessment of median nerve elasticity in patients with rheumatoid arthritis by using elastosonography (multicenter clinical study)
- Conditions
- rheumatoid arthritis
- Registration Number
- JPRN-UMIN000015314
- Lead Sponsor
- Osaka city university, Orthopedic surgery
- Brief Summary
The nerve stiffness in patients with RA measured by ultrasound real-time tissue elastography was higher than without RA. Inflammatory condition of the flexor tendon and wrist joint in patients with RA may generate fibrotic changes in the median nerve.
