An international consortium led by researchers in Nantes has developed and studied in real life a new non-invasive method for demyelinating neuropathies such as CMT1A, CIDP and anti-MAG neuropathy:
- shear wave elastography is a non-invasive ultrasound method based on changes in the composition and remodelling of nerve tissue in these degenerative diseases.
- 20 adult patients took part in this study and their data were compared with a control group of 16 people free of these diseases,
- Shear wave velocity (SWV) measurements were taken on several occasions, in different positions of the limb segment analysed, resulting in 32 measurements per individual,
- SWV appears to be markedly increased in demyelinating neuropathies.
Such a method could eventually be used in therapeutic trials.
